Benefits of Upgrading Your 6.5 Grendel's Muzzle Brake

If you’ve been shooting the Grendel for quite a while, you must be familiar with its accuracy, low recoil, and capability to hit targets over a long range (1000+ yards). But if you’re not, just know that the 6.5 Grendel is a mid-point between the 5.56 and 7.62 calibers.

The 6.5 Grendel is usually and mostly used for long range precision shooting. It’s what the cartridge was designed for. One very big hurdle is the recoil.

The 6.5 Grendel has some extra weight and recoil compared to the 5.56 (due to its size), but also a better ballistic coefficient. This means the round has a flat trajectory over long distances. Reducing the recoil of the rifle, will no doubt add to the accuracy. That’s where the muzzle brake kicks in.

The purpose of the muzzle brake is to reduce the felt recoil of a rifle. Muzzle brakes are known to reduce recoil by almost 50 percent, which will mean a substantial reduction with long-range precision shooting calibers like 6.5 Grendel.

The reduced recoil also helps with the quick realignment of sights after every shot, since the barrel deviates less. This is advantageous for hunting at mid to long ranges.

Note: Please check your local state laws to understand the permitted length of a rifle. A muzzle brake will extend your rifle’s length by a couple of inches.

Features of Great 6.5 Grendel Muzzle Brakes

Quality: The very first feature to look for in a good 6.5 Grendel Muzzle Brake is quality. Or in any product for that matter. A good brake must be made from strong, lightweight, durable material which should be able to stand the test of time, gas impingement, and natural factors.

Proper Vent Placement: A good muzzle brake must have vents aligned in a proper direction so the gasses escape properly without interfering with the recoil or function of the rifle. A vent should not be present on the bottom of the brake, as it will create an upward force when you shoot from a prone position.

Recoil Reduction: A good muzzle brake must actually reduce the recoil of your 6.5 Grendel-based rifle, not only on paper but in reality. Your brake must require little or no tuning for muzzle climb reduction, and should be easy to tune if needed.

Doesn’t Require Gunsmithing: An exceptional muzzle brake should be a plug-n-play device which is easy to install, and doesn’t require a visit to the gunsmith. Fortunately, all the brakes mentioned in this review can be installed with minimum effort. Most do not contain shims or any extra material.

Easy to Maintain: A muzzle brake will collect grime and dirt, just like the barrel does. Hence, it should be easy to clean and preferably rustproof, so you can easily wash it.

Affordable: Finally, a good muzzle brake doesn’t have to cost you an arm and a leg. There are brakes costing more than a couple hundred dollars, without the fee of a gunsmith. But keeping that in mind, our top picks won’t burn a hole through your wallet.
