When you are looking for the best scopes for 6.5 Grendel, it is essential to consider riflescopes that provide the proper combination of quick adjustments and power.

Except for bullet drop, the 6.5 Grendel is ballistically superior to the .223/5.56 in every way. 

Because of the higher BC (i.e. more aerodynamic) 6.5mm bullets, the Grendel will drift less in the wind, lose velocity more slowly, and generally be easier to shoot accurately at long range and in the wind.

6.5mm bullets are famous for flying straight and penetrating deeply.

Common FAQ

Recommended Reticles for 6.5 Grendel

The recommended reticles for 6.5 Grendel would depend on its intended use first.

The 6.5 Grendel is designed explicitly for use by the AR-15 rifle. It has an effective range of 200 yards as an intermediate, mid-range cartridge, but hunters can still go after deer-sized animals between 300-400 yards using the precision rifle for hog hunting or deer hunting.

6.5 grendel vs 223

On the other side, the 6.5 Grendel has superior ability to keep its projectile at supersonic speeds over 1,000 yards, affecting some gun enthusiasts are going for the long-range 1,000-yard recreational shot.

Considering all that above, and if you're going for short to mid-range hunting with the Grendel, you should find the fine duplex reticle, which will allow you even to make some slight flight corrections.

But if you're doing long-range, you will need the BDC or Mil-dot reticle that will enable you to correct for bullet drop and help for accurate aiming and firing at a distant target.

20 MOA base required for extreme long-range shooting with 6.5 Grendel?

The 20 MOA base is required for extreme long-range shooting, particularly if you are going to shoot 1,000-yard targets with 6.5 Grendel.

In longer words, the typical long-range scopes have 17 MRADs (58MOA) of internal elevation adjustment for both upward and downward correction.

Since you need 1.4 Mil to get zeroed at 100 yards, all you have is 7 Mil available in the scope and a typical 20MOA base will give you another 6Mil.
Using an average scope with the canted mount, you will get 14.5Mils in total that should be enough for 1,000 yards distance.

Reasons to use LPVO on a short barrel 6.5 Grendel rifle.

While the AR15 chambered in 6.5 Grendel can approach some really impressive distances, the cartridge is primarily designed for tactical rifles for close-quarters combat and short-range use.

Modern battlefields approved the reflex sights and red dot sights are irreplaceable for that type of engagements. For more information, get to “red dot sight guide” for tactical 6.5 Grendel SBR setup.

As the more effective chambering, the short barrel rifles in 6.5 Grendel get more and more popularity over the SBR chambered in 5.56. Assuming that, you may find an increased offer of low power variable optics (LPVO) appropriate for short barrel 6.5 Grendel rifles.

Today trendy LPVO riflescopes are often used in military and tactical tasks and for hunting because of their wide magnification range (1-4x, 1-6x, 1-8x and even bigger).

On 1 power for CQB, these optics are almost as fast as a red dot sight and with quick zooming to 4, 6, or 8x magnification, you have enough zoom power to be accurate at several hundred yards.

It means that with a 6.5 Grendel AR15 and mounted LPVO optics, you can cover the entire AR's effective range.

Hunting wild boar in Europe is particularly popular with driven hunt type of hunting where LPVO are ideal optics for quick, flash shooting at short ranges.
