Some cartridges deserve to be paired with excellent scopes to really maximize their capabilities. The 6.5 Grendel is one of those cartridges. Developed as an improved version of the 6.5mm PPC, the 6.5 Grendel is an accurate and low recoil cartridge for use with AR 15 rifles. Its accuracy and controllability are legendary; it’s possible to push the effective range of an AR 15 equipped with these rounds out to 1000 yards or more.
Naturally, the best scopes for 6.5 Grendel weapons will make good use of this cartridge’s excellent range and accuracy. In this guide, we’ll go over the top scopes for this exceptional cartridge and its accompanying weapon platform. Let’s get started.
What to Look for in a 6.5 Grendel Scope
The best scope for 6.5 Grendel platforms will have several features or design standards that make it stand out from the pack.
The best 6.5 Grendel scopes will have top-tier reticles to enhance their weapon’s capabilities.
Whether these are BDC reticles, which can compensate for bullet drop and help you land a shot from afar, or illuminated reticles, which can provide you with excellent accuracy during the dusk or dawn hours of the day, you should always try to find scopes with exceptional reticles to improve your odds of success on your next hunt. Naturally, the scopes we provided have great reticles in one way or another.
First or Second Focal Plane Reticle?
Speaking of reticles, you should always consider whether a given 6.5 Grendel scope features a reticle located on the first or second focal plane. Reticles on the first focal plane will slightly change size each time you switch your zoom level, becoming larger as you zoom in and smaller as you zoom out.
This provides you with an advantage in that the estimation holdover points for windage and elevation will remain accurate no matter how far you zoom in or how far you zoom out. This can help you land shots more accurately, particularly when it comes to hitting a moving target.
Second focal plane reticles can also be helpful. They never change size no matter how you change your magnification setting, meaning they are easy to use under a variety of circumstances. However, you do have to compensate for windage and elevation more intuitively in your head or do some quick math since the holdover points are only accurate for one magnification level.
Both types of reticles can be effective, and hunters usually prefer one or the other based on personal experience or their education. We provided scopes for 6.5 Grendel weapons down below with both types of reticles to give you all the options.
Easy to Adjust
Since most hunters who prefer 6.5 Grendel weapons will tend to hunt targets from far away, we found several scopes with easy to adjust windage and elevation turrets. These allow you to perfect your shot and ensure accuracy at a distance. Since the 6.5 Grendel is a high-lethality cartridge, landing the shot practically guarantees a kill, so ensuring ultimate accuracy is a necessity.
We also included several scopes that have parallax turrets which can eliminate this variable from your next shot. You should also look for turrets that have audible and tactile clicking movements, as these allow you to adjust your various settings without removing your eye from the scope.
The best 6.5 Grendel scopes will have excellent lenses that can provide better light transmission to results in a better sight picture overall. They’ll also be durable and coated with a defensive substance that can reduce the chances of them acquiring abrasion damage or collecting dirt or debris.
All of the above upgrades can dramatically impact your overall accuracy, which is why we found scopes with fantastic lenses that have been coated to improve their durability or their efficacy. You never want to pair a 6.5 Grendel with scopes using subpar optics.
What Magnification Settings?
Consider the magnification settings of a given 6.5 Grendel scope before finalizing a purchase. While the 6.5 Grendel cartridge is potentially great for shooting up to 1000 yards, you might be more in the market for something suitable for casual hunting scenarios. In these situations, scopes that have magnification settings around 10x-12x or so are more than fine.
On the other hand, picking scopes with higher magnification settings, such as 18x or 20x or higher, will be better for long-distance hunting or for target practice at extreme ranges. There’s no perfect scope zoom range for every hunter; it all depends on what you’re looking for. As a result, we provided scopes with lots of different ranges below so you can pick the best one for your needs.
