One thousand yards. Ten football fields. Over half a mile. That might sound like a ridiculous distance for any rifle round to be accurate at, but that is exactly what the 6.5 Grendel is capable of. The 6.5 Grendel is a highly accurate and low recoil round that combines with the AR-15 platform to create a weapon capable of extremely long ranges. A high end set of optics is required to fire at those kinds of ranges. Check out the list below to learn more about the ten best scope for 6.5 Grendel rifles.
Invented in 2002, the goal of the 6.5 Grendel was to create an AR-15 round that surpassed the performance of the 5.56/.223 in the 200-800 yard range. By using a shorter and larger diameter case, the creators of the 6.5 Grendel were able to pack in more gunpowder while still having room to utilize bullets with a high ballistic coefficient (BC).
Ballistic Coefficient (BC) is the measure of a body’s ability to overcome air resistance. In the world of shooting sports, the higher the ballistic coefficient of a bullet, the more accurate it will be as the shooting range increases.
The 6.5 Grendel retains a higher terminal energy at 1000 meters than both the 5.56 NATO and 7.62x51 NATO rounds thanks to that high ballistic coefficient. A lighter Grendel bullet even has more armor piercing capability than a heavier 7.62 NATO bullet at 1000 meters. In other words, the 6.5 Grendel packs at a punch at the extreme ranges it can be used at.
Even though it is capable of accurately striking targets in the 1000 yard range, that doesn’t mean that is the 6.5 Grendel’s only purpose. In fact, it makes for an excellent hunting rifle as well. This is especially true for those who want to hunt with an AR-15 in a state that doesn’t allow the common .223 cartridge for deer hunting.

How to Choose 6.5 Grendel Scopes?
It goes without saying that hitting a target at 1000 yards is a challenge. However, that becomes an even bigger challenge if you are using a scope that doesn’t have enough magnification. If long range shooting is your goal, look for a variable power scope that has a high end magnification level of 14x, 18x, or even 24x. This will go a long way towards shooting accurately at those extreme ranges.
For hunting or target shooting at more intermediate ranges, you can get away with a lower magnification level. A variable power scope also makes sense for these purposes, but a high end magnification range of 9x, 12x, or 14x will be sufficient.
Buying a scope with low quality glass is never a good idea. It might seem ok at first, but frustration will soon set in as you try to clearly see your target at long ranges. Do yourself a favor and pay close attention to the quality of the glass in the scopes you are considering. Luckily, glass quality has come a long way and you don’t necessarily have to spend a fortune to get a scope with good glass.
The type of reticle in a 6.5 Grendel scope is another important consideration. The reticle will be the tool that allows you to use your scope and rifle to its full capabilities. It can’t be changed without buying a new scope, so make sure you are satisfied with the style of reticle in the scope you choose. There are a lot of excellent options that help to compensate for holdover and windage and that even help to estimate the range of a target.
Now that you are more familiar with the features to pay attention to, read on to see the list of the top ten best scopes for 6.5 Grendel rifles!
