#1 Vortex Optics Crossfire II 3-12×56 AO Hog Hunter Riflescope

Vortex Optics Crossfire II 3-12X56 AO Hog Hunter Riflescope

The first product recommended in this buying guide and review article is the Vortex Optics 3-12×56 Crossfire II. Primarily constructed for serious shooters and hunters, I find this one of the top-rated .308 scopes due to its incredible performance and dependability.

What I am fond of about this riflescope is that it tends to excel in case you need to hunt in situations where there is low light (ex. during the early evening and the first signs of dawn). The overall build quality of this scope is top-notch. I find its V-Brite reticle as well as its huge objective helpful because both promote confidence and ease when taking shots in tough light situations.

I also find its eye relief long enough. The eye box is forgiving, too. Both these benefits can also lead to quick sight picture and target acquisition. I am also happy that I can use it to focus the reticle speedily and easily. I think it is due to the presence of its great-performing fast-focus eyepiece.

The scope comes in a single tube made of the strong aircraft-grade aluminum. This specific construction even boasts of its shockproof performance. This specific scope also boasts of its fog-proofing and waterproofing features. This is made possible with its nitrogen-purged and O-ring sealed design.

Another viable reason to fall in love with this .308 scope is the built-in adjustable objective lens. I find this feature valuable as it works in offering proper image focus while letting you remove or adjust parallax. You can also take advantage of the clear and bright views provided by its fully multi-coated lens.

Moreover, its anti-reflective coating works in boosting light transmission to almost perfect.

One issue I have with this riflescope, though, is its weight because I noticed it is built heavier compared to the others.
Pros
  • Perfect for low-light hunting
  • Long eye relief guaranteed
  • Good fog-proofing and waterproofing features
  • Offers proper image focus and the ability to adjust or remove the parallax
  • Provides clear and bright pictures
Cons
  • Slightly heavy
The Vortex Optics 3-12×56 Crossfire II is surely the best investment that a hunter or shooter like you can make. It has a rugged and tough build while also promoting dual uses – that of being a shooting scope and a hunting or tactical scope.

#2 UTG 3-12X44 30mm Compact Scope

UTG 3-12X44 30mm Compact Scope

If you want to buy a compact scope then I think nothing can beat the quality of the UTG 3-12×44 Riflescope. I instantly detected that this scope works as one of the best pieces of equipment for its price. It is appropriate to use in both long-range and professional hunting and shooting.

One of the traits that make me love this compact and reliable scope from UTG is its amazing optic that is appropriate for AR-10, AR-15, and .308 rifles, among many others. It contains several advanced features that make the process of shooting and hunting easier and more beneficial than before.

One of its key benefits is its ability to support multi-color models and personalized illumination – this is actually all thanks to the built-in innovative illumination-enhancing reticle. It even features a spectrum, which provides up to 36 colors, suiting all your environmental preferences and requirements.

I am also satisfied with its awesome low-light performance. The quality optics incorporated into this scope also has multi-colored lenses that feature an anti-glare angled sunshade. I am also completely happy that this scope lets me make adjustments on the field to promote a highly accurate target aiming experience.

This is made possible by the zero-locking and zero-resetting target turrets. Another reason to love this scope is that it is constructed in a platform with genuine strength and durability. You can even trust it for being fog-proof, waterproof, and shock-proof, promoting uninterrupted performance each time you hunt or shoot.

It also comes with a limitless parallax adjustment, which, I think, contributes a lot in the accuracy of shots no matter what the target distance is.

One issue, though, is that it is quite heavy even with its compact build.
Pros
  • Supports multi-color models and personalized illumination
  • Great low-light performance guaranteed
  • Fog-proof, waterproof, and shockproof, making it strong and sturdy
  • Comes with a limitless parallax adjustment
  • Comes in a compact size
Cons
  • Slightly heavy for its size
All things, features, and benefits considered, I can safely conclude that this is a riflescope with plenty of amazing things to offer despite its compact size and affordable price.

#3 Nikon Buckmasters II 3-9x40mm Riflescope

Nikon Buckmasters II 3-9x40mm BDC 1in Waterproof Matte Riflescope

If you are looking for a budget scope that still delivers an amazing performance then I highly suggest going for the Nikon 3-9x40mm Buckmasters II. I am actually in awe of how great this riflescope is when used together with the .308. It performs well while being offered at a truly affordable cost.

I am impressed with the simple but solid construction of this riflescope. It comes with a BDC reticle, which also features transparent ballistic circles to help long-range shooters and hunters up their ante. You can take advantage of this reticle in retaining highly accurate shots in a wide range of distances.

I am also satisfied with the reticle because it lets you put a range marker into it, preventing you from losing your target in case something bothers you or there is a need for you to reload.

As for the sturdiness of this scope, I can prove that it does not disappoint its users. It is because aside from being nitrogen-purged, it is also O-ring sealed, promoting its fog-proof, waterproof, and shockproof integrity.

With this strong and solid construction, it is built to handle heavy use and abuse no matter what the situation in the hunting or shooting field is. It does not also require parallax correction because it has already been set at a hundred yards.

The optic is fully multi-coated, which optimizes light transmission, resulting in pristine and clear quality of images. This lens also makes use of a bright anti-reflective system, allowing it to offer more than 92% of anti-reflection ability.

However, I discovered that its eye-box is quite limited, although you can easily compensate for this flaw through the built-in quick-focus eyepiece that is known for being user-friendly.
Pros
  • Affordable without losing its quality
  • Sturdy construction, showcased by its fog-proof, waterproof, and shockproof integrity
  • Optimal light transmission, thanks to its multi-coated optics
  • Equipped with a bright anti-reflective system
  • Retains accurate shots with its BDC reticle
Cons
  • Quite limited eye-box
This flaw does not cause that much of a problem, though. In fact, it does exactly what most hunters and shooters wish for while remaining user-friendly, affordable, and accurate.

#4 Primary Arms 4-14×44 FFP Riflescope

Primary Arms 4-14x44 FFP Riflescope

The next .308 rifle optics and scope that I highly advise using is the Primary Arms 4-14x (FFP) Riflescope. I made it a point to include this scope in my buyer’s guide and review article because I am completely aware of how good it is. The first thing caught my interest regarding this riflescope is its ruggedness and durability.

It has both qualities because of the high-quality aluminum utilized in its construction paired with an anodized finish in matte black color. The strength of this scope can also be instantly detected with its nitrogen-purged, shockproof, and waterproof construction.

It has an illuminated reticle, which promotes quick engagement, especially for close-range targets. It is equipped with a side-mounted knob for parallax adjustment, thereby ensuring that the reticle will remain free of parallax while also showcasing sharp target images.

I am also incredibly satisfied with the six brightness settings incorporated into this riflescope. It also features an off-notch that you can see in between every setting. Another remarkable feature is its front focal design, which is known for delivering a consistent BDC regardless of the set magnification.

I also find it incredibly easy to use this scope to hold zero and make the attained zero remain solid. It is also equipped with a ring, which makes it possible for you to match its reticle to your eye. This results in a sharp reticle for each shot.

The only problem that bothers me about this riflescope is that it is quite hard to put the chevron on long-range targets in a more precise manner.
Pros
  • Rugged and durable structure, thanks to the quality aluminum material used in it
  • Shockproof and waterproof
  • Guarantees quick target engagement
  • Allows you to adjust the parallax through the side-mounted knob
  • Equipped with six brightness settings for your convenience
Cons
  • Some difficulties in putting the chevron on long-range targets
If you consider its numerous favorable benefits, it is safe to assume that Primary Arms 4-14x (FFP) Riflescope is a fantastic piece of scope with on-point quality and accuracy, solid structure, and impressive performance on the field.

#5 Vortex Optics Diamondback HP 4-16×42 BDC Riflescope

Vortex Optics Diamondback HP 4-16x42 BDC Riflescope

Another winning product in the .308 scope category is the Vortex Optics 4-16×42 Diamondback HP. I greatly appreciate all the features added into this scope that make the lives of most shooters and hunters easier.

For instance, it has a Dead-Hold BDC reticle, which is actually favorable for shooting or hunting at various ranges, especially if they are concerned about hold-over estimation. It takes pride in its customized dot design, which aids in getting rid of guesswork when it comes to making windage corrections and holdover.

I also witnessed how rugged and sturdy this hunting scope is, especially after I took advantage of its shockproof, fog-proof, and waterproof performance. The nitrogen-purged and O-ring sealed style of this hunting scope actually contributes to the mentioned performance.

I am also glad that I discovered the versatility of this scope’s reticle. Such has more than enough versatility in the sense that you will find it effective to use on various firearms, such as slug shotguns, black powder rifles, rimfire rifles, and high-powered rifles.

It is also equipped with a fast focus eyepiece, which plays a huge role when it comes to focusing the reticle easily and speedily. This scope can also optimize the focus of the image and the removal of parallax through the easy to access side focus.

You can easily access it no matter what shooting position you have.

However, one downside I found out is that the scope’s package does not actually come with extra batteries.
Pros
  • Eliminates guesswork when making windage corrections and holdover
  • Nitrogen-purged and O-ring sealed, making it as shockproof, fog-proof, and waterproof as possible
  • Highly versatile reticle
  • Promotes ease and speed when focusing the reticle, thanks to the fast focus eyepiece

#6 Burris 2-7x32mm Scout Ballistic Plex Reticle Riflescope

Burris 2-7x32mm Scout Ballistic Plex Reticle Riflescope

The next one on my list is the Burris 2-7x32mm 200261 Ballistic Plex. Most people view it as the best scope designed for all their shooting requirements. It is made to deliver excellent accuracy. This is made possible through its posi-lock system with a retractable steel post assisted by a coil spring.

This specific feature works in locking the accuracy firmly and securely into place. I am also glad about the way this scope is constructed as there is an assurance that it is fog-proof, waterproof, and recoil-proof – thanks to it being nitrogen-purged.

Another advantage of this scope is that it features a lens with a diameter greater than the majority of its competition. This results in a sight capable of throwing off clear pictures no matter what the situation or environment is. It also acts as a slim optic capable of offering low to medium magnification.

This makes it possible for you to place it well forward on the .308 rifle, leading to the ability to keep your two eyes locked on field targets whether you are sitting or making movements at full speed. I like the multi-coated lens of this scope too as it delivers amazing brightness and clarity.

It has a coating, which works in getting rid of light glare while offering incredible light transmission up to a max of 95 percent. The way it performs also promotes ease in hunting even if you are in a surrounding with conditions that are not that ideal for you.

It also boasts of its tightly controlled and generous eye relief, providing you with a crisp and full view without dark rings at the edges. This leads to speed target acquisition.

However, it is not equipped with mounting hardware, which is one noticeable flaw.
Pros
  • Promotes a high level of accuracy
  • Known to be fog-proof, waterproof, and recoil-proof
  • Amazing brightness and clarity guaranteed by its multi-coated lens
  • Uses a lens coating, which gets rid of light glare and promotes high light transmission

It is an amazing riflescope, which uses the incredible Duplex reticle, making it perfect for general purposes. It is equipped with a fast focus eyepiece, which can speedily focus your reticle through your eyes and promise to deliver a target acquisition, which is locked on.

I am also pleased that this riflescope is built to be both strong and tough, as you can see in its 100 percent fog-proofing, shock-proofing, and waterproofing properties. I also discovered how amazing the lens coating used in the riflescope is after I discovered how it helps in increasing light transmission and boosting its abrasion-resistance.

It can also withstand the harshest recoil. It is because of its 6061-T6 aircraft-grade aluminum built designed to make the whole scope even tougher and sturdier. This scope also utilizes a system designed to provide additional minutes of shooting light while significantly lessening glare. With this, expect premium image quality.

The ruggedness of this riflescope also makes it ideal for heavy recoil. It is possible to use this one on all ammunition and rifles without losing zero. You can even expect it to handle air guns, slug guns, and muzzleloaders.

The eye relief is also plenty enough, preventing any instance, which can lead to a blacked eye.

In terms of drawbacks, one complaint I have is the slight difficulty in monitoring the turrets revolution.

  • Can significantly lessen glare, improving the quality of images
  • Works for heavy recoil
  • Compatible with various ammunition and rifles without losing zero

Nikon P-Tactical .308 4-12X40 Matte BDC800

For those who are in search of a tactical scope, the Nikon P-Tactical 4-12×40 is perfect for them. I suggest the use of this tactical scope because of its dependability and sturdiness. It is dependable and sturdy as it does not crack nor fog up even after heavy abuse and several ammunition magazines.

The lifetime warranty and advanced optics of this scope are also among its best benefits and features. I am also impressed with the lens used in this scope as it makes it powerful. It features a multi-coated optic, which promotes up to 98% light transmission, giving you a bright and clear image whether using it day or night.

With that, I can confirm that it also works as an amazing night vision scope. The matte black finish also makes this scope look even stronger and sturdier. I also sensed the versatility of this Nikon riflescope upon discovering that it is compatible with a wide range of rifles.

The fact that it is flexible also ensures that this scope can help in promoting ease and convenience during each shooting session. I like the built-in locking and zeroing mechanisms of this scope as they perform really well. It guarantees a higher number of shooting sessions with a lower risk of touching or complicating the zero.

It also makes use of spring-loaded turrets to promote an instant zero capable of holding several ammunition magazines. The flexible zoom range provided by this scope also works in satisfying the majority of hunting and shooting demands by offering the field of view and the detail at the low and high end, respectively.

However, I find its adjustable mag ring a disadvantage because it does not feature a notch that can promote ease in manipulating or adjusting the magnification.
Pros
  • Guarantees an almost instant zero through its spring-loaded turrets
  • Can satisfy most hunting and shooting demands, thanks to the flexible zoom range
  • Compatible with numerous rifles
  • Provides up to 98% light transmission
  • Comes with a lifetime warranty
Cons

FSI Sniper 6-24x50mm Riflescope

Another scope that is perfect for the .308 Sniper is the FSI Sniper 6-24x50mm Scope. I am impressed with its suitability to and compatibility with a wide range of shooting scenarios and situations. This is made possible through its illuminated Mil-Dot reticle, which you can switch from one color to another to suit your environment.

I am greatly amazed at this scope as it is constructed using the T6 aircraft-grade aluminum, which promotes its ruggedness and sturdiness and showcases its ability to handle heavy recoil. It is manufactured in a specific manner that it can take heavy use and beating.

Aside from being fog-proof and waterproof, this scope can also resist reflection, glare, and abrasion, thanks to its O-ring sealed lens, nitrogen-filled barrel, and multi-coated optic system. Note that this scope is more suitable for hunting compared to target shooting.

It has a rugged body and features turrets that promote highly precise adjustments. In other words, you can place highly accurate shots each time you look for a game. The ball-bearing turrets are also easy to control, giving you the best feel when making adjustments.

It also has lockable rings for its windage and elevation turrets. This is a big advantage as it works in making your settings secure. You can also take advantage of the impressive adjustable optics that let you alter the objective lens’ focus to fix any distortion in the parallax.

You can do the adjustment from the front, which is helpful in optimizing accuracy and clarity without any hassle. I also appreciate the suitability of this .308 scope for long-range shooting.

One issue, though, is the low life of its batteries that require immediate and frequent replacement.

I can also say that the Nikon M-308 SF 4-16x42mm Riflescope is a fantastic choice for anyone searching for a good long range scope designed for the .308 offered at a reasonable price. As its name suggests, it is built for the .308 Win round. I discovered that it is appropriate for long-distance engagements.

It also offers shooters with a user-friendly Nikoplex reticle, which is unique and distinctive. This results in a scope that has vital points of aim to certain ranges. Another amazing benefit of using this type of reticle is that it is equipped with an elevation cap with markings in the form of yards. This promotes a clean look overall.

It does not cause dots and hashes to clutter your view. In fact, you can expect it to deliver an undisturbed clear view through the fine crosshairs. I am fond of the variable magnification of around 4-16x delivered by this high-powered optic.

It also boasts of its 42-mm objective lens that makes it possible for this riflescope to be mounted low while still remaining large enough to offer a clear and bright image. The scope uses the aerospace-grade aluminum alloy as the main material for its body. It also has a fog-proof, shockproof, and waterproof interior.

I am satisfied with this scope as it showcases its ruggedness as well as its variable magnification that assures anyone of a wonderful experience on the field.

I like the built-in first focal plane reticle integrated into this riflescope. It is LED-illuminated, allowing it to handle long-distance marksmanship and close quarter battle. The fact that it belongs to the VCOG or the Variable Combat Optical Gunsight category also offers a strong advantage as it promotes easy target engagement.

Buying Guide

What Makes a Great .308 Scope?

best scope for 308 sniper

The .308 Winchester is probably the most popular hunting rifle ammo in the United States, and maybe even the whole world. Not only does it have an excellent range (1000 yards according to the USMC), it is also one of the most consistent performing ammunition out in the market today.

If you want to make the best use of its long effective range, you will need a scope that can give you a good sight picture up to 800 yards. Note that unless you are an army-trained sniper, aiming for 1000 yards is a bit too much to hope for.

The .308 Winchester also does not have that much of recoil, so eye relief is not really a priority. However, you still should not place your face too close to the eyepiece because you might not be able to brace yourself enough to prevent the rifle from kicking back. This means that something with around 3-1/2” to 4” eye relief will be fine.

The magnification power and other aspects of the scope you should get will depend mostly on where you will be using your rifle the most. If you will be using it for deer hunting or any other form of hunting, you need to keep the scope as lightweight as possible.

When you are game hunting, you want to get as close to your target as possible. You will not risk it by shooting at it from 800 yards away. At most, you will be shooting from 150 yards, even when you are using a .308 Winchester, so a scope that maxes out at 9x or 12x is more than enough for your needs.

What Magnification Do You Need?

best scope for 308 AR

In general, the type of scope magnification that you should get depends on what you will be using the rifle the most for. If you will be using the rifle for game, elk, or deer hunts and you will only be shooting up to 150-200 yards, a scope with around 6-9x power will suffice. When you are hunting in the woods, your target will not be waiting for you while you make slight adjustments for windage and bullet drop and of course, you will not be shooting from 800 yards away anyway.

On the other hand, if you will be using the .308 rifle in the shooting range and you will see if you can do the 1000-yard shot that USMC snipers routinely do, then you should get a scope that has a high magnification power, something that at least has 24x magnification range is the minimum that you should strive towards. Also, remember that something that has a BDC reticle will make taking long range shots much easier.

Should you choose a fixed magnification or a variable zoom scope? If you are out hunting, you need something that is convenient to use. Choose a hunting scope that you do not have to tweak to get a good sight picture, so a fixed magnification is the best choice.

You just peek into the scope and place the crosshairs on your target and then pull the trigger; no fuss, no mess. If you will be shooting in a range and you have all the time in the world to line up your shot, then a variable powered optic or variable zoom will work the best.

Factors to Consider when Buying a Scope for 308

best 308 scope

So what are the things and factors to look out for when shopping for a good .308 scope? Here are just some:

Magnification

When you are buying a scope for a .308, the magnification power is the first thing that you should check out. Now, how much magnification you need will depend on your particular use. Note that just because a scope has a higher magnification power than another, this does not instantly mean that it is better all around.

Sometimes, you will not need ultra-high magnification power, especially if you will be using the rifle for deer, game, or elk hunting. On whether or not a fixed zoom or a variable zoom is best, again it is very subjective. For hunting, you need your scope to have the ability to acquire the target easily the moment you peek into it.

Eye relief

For the .308 Winchester, the eye relief is not much of a concern, mainly because it does not have quite as much recoil as other ammunitions with the same effective range. With that said, it does not mean that eye relief should be completely ignored.

If you are a beginner at using a rifle, you might not be able to fully absorb the recoil of the rifle using your shoulder, which means that it, along with the scope, will have a way to go before it stops. If your eye socket is in its way, it will hurt and possibly cause serious injury so get a scope with at least a 3-1/2” to 4” eye relief.

Weight

best compact scope for 308

The weight of the scope can be due to a number of sources. Most of the time, the majority of a rifle scope’s weight comes from the lenses it has inside, so you will need to make a compromise at this point.

For instance, if you want a light scope, then something that has a fixed 9x zoom with a 42mm objective lens is what you should get. Sure, it might not be usable for hitting targets 900 yards or more away, but if you will be using the scope for hunting, you will love having something that will not add any more weight to your gear.

Reticle

The reticle or crosshairs in your scope will depend on how you like to shoot. For instance, if you like shooting long distance, a BDC reticle might be good for you. These reticles have millings so that you can take into consideration the bullet-drop, and windage and elevation adjustments with every shot.

There are many different kinds of reticles you can choose from, and there is no one or two reticles that are actually better than the rest. It will all depend on your shooting style and which reticle you are comfortable using.

Objective lens

The objective lens is the one at the front of the scope, and its job is to allow light to come into the scope and give you a clearer sight picture. The bigger the objective lens is, the more light gets into the tube and the clearer the sight picture you can get. This is great when you are shooting in poor lighting conditions and you need to get a clear shot at your target.

However, as mentioned earlier, the bigger the lens system is, the heavier it is, so you need to find some sort of middle ground so you can get the best image quality but not add quite as much weight to your rifle. For hunting, a 42mm objective lens will do fine, although you could also get away with using 50mm if you can find one with a fixed zoom so it will not be too heavy.

Parallax Adjustment

best scope for 308 long range

In short to mid-range scopes, parallax is not really an issue because those scopes are already parallax-adjusted to those ranges. However, on a long-range scope, parallax is something that you have to deal with constantly.

Parallax happens when the reticle is not in the same focal plane as the target. As a result, the reticle will move about over your target when your eyes move in relation to the scope. If you are looking for a long range scope, find one with parallax adjustment. Those are the ones with a turret at the top of the tube.

Weatherproofing

This is extremely important if you will be using your rifle primarily for hunting. It is quite rare that when a person goes out hunting, it will be a perfectly clear day with nary a dark cloud in sight. Most of the time, you will be hunting in the rain, thick fog, or a combination of both.

You will need a scope that can handle whatever Mother Nature can throw at it. Ideally, you should get a scope that is waterproof, dustproof, fog-proof, and also a bit shock-proof, so you do not have to worry about banging your scope on the trees and rocks while you’re hunting.

Lens Coating

The lens coating of a rifle scope enables the lenses to absorb as much ambient light as possible from low light environments while reducing the amount of glare that will make it hard for you to aim properly. The lens coating also reduces the amount of light reflected by the lenses.

This is important because reflected light does not only add to the glare. It also gives out your location to your target. Lens coating comes in coated (single coat, single external lens only), fully coated (single coat, both external lenses), multi-coated lenses (multiple coats, single external lens), and fully multi-coated optics (multiple coats, both external lenses).

Frequently Asked Questions

What size scope for AR .308?

best scope for 308 hunting

There are many different sizes of scopes that can fit on an AR .308, and there is not one that can be called the “best”. It is purely subjective. You can use any size of scope that you want. You can even use the biggest one available if you want, as long as it does not interfere with the functions of the rifle. However, if the scope that you mount on your rifle does not suit the use that you are planning for it, then it is pretty much worthless.

The objective lens is one of the parts of the scope that dictates how big it will be. For instance, a scope with a 50mm objective lens is much bigger than one that has a 42mm objective. Although the 50mm objective scope can gather in more light, it is much too bulky for most people to use it for serious hunting. Just choose the size of scope that fits your needs.

How to sight in a rifle with a .308 scope?

It does not matter if you have a sophisticated rifle scope mounted on your .308 rifle. If it is not sighted in properly, you will not be able to use it to hit any target at any range. If this is the first you are using a rifle scope, here are the steps on how to sight it in properly.

1. Ensure that the scope is installed properly:

Almost all modern rifles available today already come with built-in mounting systems for scopes. Regardless if your rifle comes with pre-drilled and tapped holes for screwing in scope bases, or if it has a grooved rail system, like the Weaver and Picatinny rail systems, you need to make sure that the scope mounts and rings that you will get actually fits the mounting system of your rifle.

Do keep in mind that there are some scope rings that will only fit in certain types of scope bases, which is why it is of utmost importance that all your components match each other.

2. Adjust the eye relief:

Position your eyepiece so that you can see a clear image when you peek into the scope. You need to fine tune the scope and create the right amount of eye relief, which is the distance between the back end of the scope and your eye.

This is a key component to sighting your scope because you have to be sure that when you fire the rifle, the recoil will not send the scope far enough to smack you in the face and cause serious injury.

3. Set your rifle on a level shooting position:

To sight your scope properly, you need to set it on a stable shooting position. You can either use a bipod, or better, clamp your rifle on a shooting bench with a mount.

The thing about the rifle mount is that it can absorb almost all of the recoil while still holding your rifle securely. There are many different mounts that you can choose from, but if you are going to get one, choose the one specifically designed for scope sighting.

4. Align the reticle:

Most newbie shooters do not take into consideration the alignment of their scope’s reticle when they are sighting in their new scopes. When the reticles are not aligned to the directions of the elevation and windage adjustments, it is called “reticle cant”.

This is important, especially for .308 scopes because they are meant for long range. A reticle cant can result in your shots missing either right or left of the target, especially if the target is beyond 250 yards away.

5. Set the MOA (Minute of Adjustment):

Setting your scope’s zero involves several steps, and it is easiest to do it in an outdoor shooting range, mainly because you will need to set targets at multiple distances that are at least 100 yards away from you. In addition, you need to keep your rifle stable, so you will need a mount for it.

Most rifle scopes allow you to adjust the crosshairs in ¼ MOA increments, which equates to ¼” movement for every click when sighting at 100 yards. Most professional hunters set their MOA to 1/8” and ¼” MOA click value. To make your bullet hit an inch, or one MOA at 100 yards, you need to turn the elevation or windage turret by four clicks. The click value increases by ¼” per 100-yard increase in distance.

6. Fire three shot groups:

Once your rifle is on a level base, fire three shot groups at the target then take note of where your shots land on the target. Depending on your use, you might want to sight in slightly high at 100 yards away then aim at the center of the target at 200 yards. It depends on you how to set your MOA. The important thing is that you are familiar with your MOA settings so you can quickly adjust at different ranges.

7. Keep tweaking until you are satisfied:

You should try different distances and repeat the sighting in process so you can consistently hit grouped shots that are close to the bull’s eye regardless of how far they are. Do keep in mind that you should not just factor in the rifle scope and distance from the target, but also the direction and strength of the wind and other environmental variables.

Nikon M-308 vs. P-308

Between these two riflescopes made by Nikon, the M-308 is the higher-end model. These two riflescopes have very similar sets of features, but the M-308 does have a couple of “premium” features that are not in the P-308, like the parallax setting, higher magnification, and large range of FOV and eye relief.

However, the P-308 sells for just half the price of the M-308. This is also combined with the fact that the additional features of the M-308 are somewhat niche features for long-range shooting. Value-wise, the P-308 is the better choice of these two scopes.

Leupold Mark AR MOD 1 3-9x 40mm vs. Nikon Buckmasters II 3-9x 40mm Riflescope

Again, these two riflescopes from different companies have pretty similar features. The Nikon Buckmasters II and the Leupold Mark AR MOD are both made for short to medium range shooting. The two also have almost identical profiles. However, the Nikon Buckmasters II is selling for just half the price of the Leupold.

Granted, the Leupold Mark AR MOD 1 was made entirely in the United States, if you do not have much in terms of budget, the Nikon Buckmasters II is one of the best scopes for the money.

Leupold VX-2 3-9x40mm Riflescope vs. Leupold VX-3i 3.5-10x40mm Riflescope

These two riflescopes made by Leupold are both good scopes, but one is much better, and that one is the VX-3i. The VX-2 is kind of like the Jack-of-all-trades, in that it does a little bit of everything. It is the kind of hunting scope that you take with you for a regular, fun weekend hunting trip.

The VX-3i, on the other hand, has a little more to offer underneath its matte black exterior. Sure, the VX-3i is a whole lot more expensive than the VX-2, but that is because it has a whole lot more features crammed into it.

If you are looking for a regular, reliable scope, go for the Leupold VX-2. It is also the perfect choice if you want something a bit more special and one that can push the .308 to the test.

Conclusion

The .308 Winchester still holds the title of being the most popular ammunition today because of its long effective range and its consistent reliability. You need to take advantage of the .308 Winchester’s accuracy and consistent performance by pairing it with a long-range scope that will help you make each and every shot hit its mark.

Unlike other rifles, there is little to no contention about using a scope for .308 rifles on the market mainly because you can only shoot accurately up to 250 yards using just the iron sights. If you want to accurately shoot targets that are 500, 700, and up to 1000 yards away then you really need to look for the best scope for .308.
