In fact, it is capable of switching from long-range to short-range viewing or vice versa with ease. The illuminated mil-dot reticle used in this riflescope is one reason behind such capability. This specific reticle also promotes ease in getting a clear view of your aimed target, giving you an idea of what exactly it is.
Alternatively, it also makes use of crosshairs with dots at the center, not a solid line. What is great about the dots is that they promote ease in making visual adjustments on the distance or windage without the need to make adjustments on the actual riflescope.

What Makes a Great 6.5 Grendel Scope?
The 6.5mm Grendel is a low-recoil, high-accuracy ammunition that is specifically designed for use by the AR-15 tactical rifle. It has a maximum effective range of 200 yards (the distance where you do not need to compensate for bullet drop), which means it can benefit from a good medium-range rifle scope.
This also means that a scope with a magnification power of up to 16x will allow you to accurately shoot the Grendel at targets beyond 200 yards. The “best” scope to use with the Grendel will depend on your intended use for it. For instance, if you will be using your AR mostly for target shooting down in your local range, then you might want to use a long-range scope so you can test the limits of your rifle and ammunition.
On the other hand, if you will be using the Grendel ammo for hunting then you will benefit the most from a scope with a magnification of 4x to 12x. A medium-range scope will allow you to get close enough to your target to ensure a solid hit but still far enough that your target will not notice you.
To find a great Grendel scope, you need to take into consideration not just the capabilities of the ammunition but also what you will be using it for most of the time.
What Magnification Do You Need?
The 6.5 Grendel has an effective range of 200 yards but it can still go as far as 300 yards with a bit of bullet drop, so you will need a sufficiently powerful scope to make full use of its capabilities. The Grendel is primarily designed for tactical rifles, specifically the AR-15, and that means it is proficient in close quarters combat, short-range, and medium-range shooting.
It is also appropriate for long-distance shooting up to 600 yards or so but you will need to compensate heavily for bullet drop and windage. For CQB, you will find reflex sights or red dot sights quite beneficial because they allow you to aim at your targets quickly. You just raise the rifle and place the red dot at the targets center of mass, which you can do in just a fraction of a second if you’re good.
Reflex sights are great if you are planning on joining shooting competitions, like shooting galleries, or speed shooting events. For short and medium range shooting, a variable magnification scope is ideal. A rifle scope that has a range of 3-9x or 2-12x magnification is the usual choice as these are best for plinking.
Now, if you will be using the rifle for hunting, a fixed magnification scope might be better as it allows for faster target acquisition and does not need any turret adjustment whatsoever. These scopes are usually raised a bit from the rail, so you can still use the iron sights of the rifle. For hunting, usually a 3x to 9x fixed magnification scope is the popular choice.
It is a bit difficult but you can still use the Grendel to shoot at targets up to 500 yards. You just need the right scope to do so. For that distance, a scope that has a magnification of 16x to 20x will suffice.
In addition, the reticle should have bullet drop compensation and windage because the bullet tends to drop by quite a bit after 400 yards. It is also important to set your rifle on a stable base because when you are shooting that far, every little shake will seem like an earthquake when viewed through the scope.
Factors to Consider when Buying a Scope for 6.5 Grendel
If you are looking for the best optics for 6.5 Grendel rifle, but you do not know what you need to keep an eye out for, the following guide will be of great help. The following items are the main factors that you need to take into consideration when you are out shopping for a new scope for your rifle:
The magnification of the scope that you need to buy will mainly depend on what you will usually be using the rifle for. There is no such thing as a Jack-of-all-trades rifle scope. Some claim that they can do everything but when put to the test, they all come out as average. You need to figure out first what kinds of activities you will be using your rifle for.
If you will be using the rifle mainly for plinking or target shooting in your local gun club’s range, you can use a scope that has variable magnification – either 2-12x or 3-9x will work well. Although not advisable, you can also use the Grendel for long-distance shooting. For that, you can use optics that go up to 18x or 20x.
On the other hand, if you originally bought the gun for home defense or for prepping, then you need something that will allow you to acquire targets quickly, something that you do not have to adjust. For this purpose, a reflex sight or a red dot sight is your best bet. When the enemy is just a few yards away, the last thing that you want to do is close one eye and have the other one look through a scope.
For hunting purposes, you need a scope with a fixed medium-range magnification. If you will be hunting small game, a 9x fixed scope will be fine for your needs. It will allow you to get a good look at your target prey but not so close that you can scare it away.
The eye relief is the minimum distance between your dominant eye and the focal lens that can still result in a clear sight picture. It is important because it prevents the scope from crashing into your eye after a particularly strong kickback from the rifle.
The 6.5 Grendel is actually designed to be low recoil, which means a scope with a short eye relief will work. However, if you still want to play it on the safe side, you should get a scope with an eye relief of at least 4.5 inches or so.
Just like the magnification, when choosing the reticle design of your scope, you need to consider what you will be using it for. For close quarters, you need something that you can use to aim quickly, so a red dot reticle is perfect. You do not have to actually aim properly. Just center the red dot on the target’s center of mass.
For short and medium-range shooting, which means you will most likely be shooting up to 200 yards away, the maximum effective range of the Grendel ammunition, you can use the basic Duplex reticle. This reticle will allow you to center your aim properly and maybe even make some slight flight corrections.
In addition, if you will be using the scope in low-light conditions, then you need to get a scope that has an illuminated reticle. In any case, if you just want good visibility in any lighting condition, then this kind of reticle is your best choice.
Objective lens size
The objective lens is the one in front of the scope. This is the part that lets light into the scope, thus providing you with a brighter sight image. The larger the objective lens, the more light it lets into the scope. However, the caveat is that it also adds quite a lot of weight to the scope.
If you will mainly be using your firearm on the firing range, then there is nothing stopping you from getting a scope with a 50mm objective lens. On the other hand, if you will be using the rifle for hunting, the maximum should be around 30mm, as every gram of weight counts when you are in the wilds.
The lens coating is the film, or layers of film, applied on the objective and focal lenses to make them anti-reflective and prevent glare. The more layers of anti-reflective film there is, the better it performs.
Waterproofing and fog-proofing
These qualities are important if you will be using your scope for hunting purposes. You need to make sure that the scope you get actually has decent waterproofing and fog-proofing.
Usually, what manufacturers do is make sure that the body of the scope is completely air tight then fill it with an inert gas, usually nitrogen, before sealing the ends. This prevents fog from forming inside the lens. The waterproofing comes from the strong seals that prevent the nitrogen from escaping.
The 6.5 Grendel is one of the most popular ammunition for tactical rifles and for good reason. This ammunition is not just extremely accurate. It also has a low recoil, which makes it easy to use, even for beginners. As accurate as the Grendel ammunition is, it can only benefit more if you pair it with a good scope.
With the best scope for 6.5 Grendel rifle, you can effectively increase the range of the Grendel ammo, which means you can hit target that are as far as 500 yards. If you want to make the most use out of your Grendel rifle, you need to get the right scope that fits your needs and intended uses.
