The Best .300 Blackout Muzzle Brakes of 2020

Not only does a muzzle brake give you the best practical benefits, but it also provides that tactical appearance to your rifle. The .300 Blackout round was designed for special forces to use in specific tactical conditions anyway, so having a muzzle brake for your .300 Blackout round is almost always a must. 

What Is Muzzle Brake?

Muzzle brakes are essential mounts that thread onto the end of your barrel to redirect the propellant gasses from every shot you take. It mainly serves 2 purposes, first, it reduces your felt recoil, and second, it can be designed to reduce muzzle rise as well. Both these features would make it easier for you to make follow-up shots while increasing your comfort, control, and accuracy.

Buying Considerations for A .300 Blackout Muzzle Brake

Attachment

The main factor of choosing a great .300 Blackout muzzle brake would be the method of attachment. While some have to be installed by a gunsmith, some can be simply threaded or twisted on. Most people would prefer muzzle brakes that are pinned to the barrel as it gives the most secure fixture. Alternatively, clamp-on muzzle brakes are also a great option.

Size and weight

Besides attachment issues, you should always get a .300 Blackout muzzle brake that’s of the appropriate size and weight for the .300 Blackout round and your rifle. Having any unnecessary weight at the end of your .300 Blackout rifle barrel would change the handling and the overall balance of the rifle, which will affect the gun’s accuracy.

Flash suppression and venting

Some muzzle brakes come with flash suppression features as the baffles and vents can be arranged to reduce the muzzle blast so your position won’t be exposed. Many muzzle brakes have no vents at the bottom, which is great as it will prevent the muzzle brake from blowing up dust which in turn, reduces your visibility.
