Through the magic of computerized fluid dynamic design Custom Muzzle Brakes presents their Extreme Duty Low Concussion Rifle Muzzle Brake for .308. The crown of this brake is an extra deep semi-spherical depression that helps it to manage concussive forces like no other 308 muzzle brake we know of. This low concussion muzzle brake uses linear baffles and a large expansion chamber to mitigate recoil forces without using the standard port designs we’re used to. As a result, this brake requires no timing, just place it as desired with a muzzle lock nut to lock it into place.

The punishment and destructive nature of the blast concussion created by the use of many ordinary muzzle devices make this 308 muzzle brake a tactical operator’s dream. If you find yourself in close quarters combat situations with any frequency, this is the muzzle device you want on your rifle. The Extreme Duty Low Concussion Brake will keep you solidly on target without punishing you and the rest of your team with concussive forces that can be more than a distraction. Even if you’re not a tactical operator, you can benefit from the performance of this brake at the range. It’s good enough to be in the scout or sniper’s bag of goodies, yet it’s within reach for the weekend shooter who wants recoil control without the concussion that often comes along with it. 

The Custom Muzzle Brakes Extreme Duty Low Concussion Muzzle Brake is manufactured in the United States on precision machining equipment. Each one begins with quality U.S. steel and is finished in Mil-Spec Black Phosphate coating. The entire outer surface is knurled and fluted, details that let you know that this is a finely crafted firearm accessory, not a generic can off the shelf.
