The 6.5mm Grendel is an intermediate cartridge manufactured as a low-recoil, high accuracy ammunition to extend the range of AR-15 rifles past 1000 yards at super speeds and magnification level and right scope and good scope for 6.5 Grendel.

Night Vision

The Criteria – How To Identify A Good Scope For 6.5 Grendel?

Intended use

The very first fact to take into consideration is your intended use of the scope for 6.5 Grendel. Choose whether you’ll be using your scope for close quarter hunting, bench-rest shooting, long range hunting, night hunting, or precision shooting competitions. See if it comes with light transmission and if it is waterproof and fog proof. 

Since the use will ultimately decide the combination of light transmission features for the scope for long distance and a fast focus eyepiece, you want to know exactly which features are a great necessity and which you can do without, in order to keep your cost down. This point is not just specific to the 6.5 Grendel windage and elevation but to every calibre that are out there. 

Focal Plane

In a First Focal Plane (FFP) scopes on the market, the reticle zooms in its size as you zoom over the target. Whereas in a Second Focal Plane (SFP) scope, the reticle remains the same size regardless of the zoom/magnification. With the exception of hunters who are shooting, the SFP scope will be sufficient for your needs. You can find more information about FFP vs. SFP on the internet with a great range magnification range. 

The basic difference between the two is that the turret values of its magnification range have to be adjusted for the SFP over long ranges when the magnification is altered. However, in FFP, these values don’t change with magnification. Furthermore, FFP scopes are more adjustable and expensive magnification settings and accuracy. 


 If you plan to shoot for long range targets, with variable ranges, then consider choosing a range finding BDC/mil-dot reticle. If shooting at less than 500 yards, a duplex/German reticle will be accuracy less complex eye box, complicated, and appropriate long range scopes and short range scopes (check the adjustable  magnification setting for best distance shooting experience).  

Easy to Adjust

Make sure the turrets are convenient to adjust, and you don’t need an Allen key or screwdriver every time to alter the windage and elevation. The 6.5 Grendel magnification range can be used for variable long range shooting purposes, so you may have to make quick adjustments to the magnification settings.


 Make sure the scope is properly sealed with nitrogen/argon gasses to avoid any moisture or haze on the scope. Make sure that the scope is of good quality, waterproof, can resist shocks, has proper eye relief, and adjustable retains zero.

Frequently Asked Questions (FAQs) 

What is the best barrel length for a 6.5 Grendel?

The two 6.5 Grendel barrel lengths that are best suited for hunting purposes and application are the 24 inches and 2 inches barrels. Shorter barrels may be applied, however, beyond slightly lighter weight and more handy silhouette, they have no benefit and give up velocity. However, they are great choices for general shooting or a utility rifle.

Which Magnification Is Ideal For Your 6.5 Grendel Scope?

The 6.5 Grendel has an effective range of 200 yards but it can achieve 300 yards with bullet drop. The 6.5 Grendel is a tactical rifle, in particular AR 15 which is effective in short range and mid range shooting. Regardless, the 6.5 Grendel also can hit longer distance, approximately 600 yards but you’d similarly need a bullet drop and windage.

For short and mid range shooting, a variable magnification scope is ideal. A rifle scope that has a range of 3-9x or 2- 12x magnification is the most desired as they are best for plinking. As for hunting applications like deer hunting, a fixed magnification scope is more ideal which are raised from the rail so you can also optimize your iron sights. Hence, a hunting scope should be ideally 3x to 9x fixed magnification.
