Muzzle Brakes Are Loud

Those extra ports around the body of a muzzle brake give the expanding gasses multiple paths to vent. Without delving deeper into the acoustics mechanisms, just know that muzzle brakes will be significantly louder. Typically it becomes impossible for noise-sensitive shooters to fire a muzzle brake-equipped rifle without earmuffs. 

Another small issue with using these brakes is that the side venting gasses creates more of a hazard to objects and people to the sides, so take proper precaution.

Does Diameter Matter?

Some people argue that any muzzle brake with a diameter larger than the diameter of the bullet works just fine. Well, then the question is. If it does work fine, why are their specific caliber brakes being manufactured?

Yes, a larger brake will work to a good extent. But getting a brake appropriate in diameter for the 6.5 Grendel will be more effective at controlling the recoil. All the brakes compiled in this review have been specifically designed for the 6.5 Grendel.

Hybrid or Simple Design?

Some basic design muzzle brakes help only with mitigating the recoil. However, hybrid muzzle brakes help with reducing the recoil and also the muzzle jump. Hybrid brakes have more strategically placed vents. However, on the flip side, these brakes are also a tad hectic to clean. 

Check the Thread Specs!

You got to have a barrel with a threaded muzzle to install a brake. It is important to ensure that you have the exact thread pattern as the brake you choose for proper installation. This is small but common important to miss when buying a brake. 

Installation and Regular Maintenance

There are muzzle brakes that require specialized tools for installation. Then there are some which can be mounted or dismounted with bare hands. The ease of installation and speed of changing the brake decides what application it would be put up to. 

It is also important to consider that a brake requires regular cleaning. Just like the barrel. Brakes with smaller ports require even more dedicated cleaning to ensure proper functionality.

What Recent Buyers Report

Users were baffled with the aesthetics, ease of installation and performance of this brake. Some even reported the recoil dipping down to non-existent levels. The zero retention and self-timing capability makes it even more admirable. The price is slightly more than some counterparts, but it offers amazing value for the money considering its features.

Why it Stands Out to Us

The Area 419 brake has an innovative and sturdy design. The self-timing brake doesn’t turn as you torque the collar to lock - simply level the brake and push the brake to lock it into place.

Who Will Use This Most?

The brake is ideal for competitive shooters. Especially snipers. The brake is short, low-maintenance and offers quick switching without the need to adjust zero. That makes it great for tactical applications as well. If you are using a 6.5 grendel rifle, you ought to have this brake for optimal performance. The universal adapter also allows you to easily swap from brake to suppressor in under 30 seconds.

Bottom Line

The Area 419 Hellfire muzzle brake is the exemplar of an ideal brake for a rifle. The universal adapter eliminates the need to worry about thread pitch. Plus the easy installation, zero retention and self-timing capabilities with significant recoil and muzzle rise reduction make it just the perfect package. The price is higher, but definitely worth it.

Benefits of Upgrading Your 6.5 Grendel's Muzzle Brake

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

Let's look at the features that your 6.5 Grendel muzzle brakes should have:


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.


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.


A muzzle brake helps with reducing the felt recoil, and hence the overall accuracy of your rifle. A good muzzle brake for 6.5 Grendel should be of good quality, have proper vent placement, and be easy to install and clean. The 6.5 Grendel is a long-range shooting cartridge with a lesser recoil and is apt for precision shooting. Using a muzzle brake reduces the recoil further to let you shoot accurately.
