When you need a muzzle device to handle both muzzle rise and recoil, but you really don’t want a big can sitting out front to get in the way and throw your balance off, the Custom Muzzle Brakes AR-15 Q-Type Extreme Duty Muzzle Brake is the device for you. Since it’s made by the folks at Custom Muzzle Brakes, you know it isn’t just hype. Muzzle blast management is their specialty, not just a sideline they’ve added to generate cash.

The Q-Type Muzzle Brake is the go-to device when you want maximum control over the forces that cause muzzle rise and recoil. This muzzle device started with its roots in the NATO design and under the careful hand of Custom Muzzle Brakes’ design and manufacturing team it has been optimized to perform at an outstanding level with a variety of different cartridges. 

The Q-Type Muzzle Brake uses both standard and subnormal baffle types together to maximize recoil management and blow back like no other brake on the market. This brake features vertical gas ports which manage muzzle rise when set at 12-o’clock. If you choose, you can time the Q-Type Muzzle Brake to mitigate torque, removing excess movement there as well. Less movement after firing gives you better accuracy, faster follow-up shots and better target acquisition. 

This offering from custom muzzle Brakes is no pampered lap dog. This piece will serve you just as well in real-world tactical applications as it does in range-based applications. It’s made of hardened American steel to withstand the harshest conditions as well as exposure to caustic military grade rounds. No matter where you put it to work, the Custom Muzzle Brakes AR-15 Q-Type Extreme Duty Muzzle Brake won’t let you down.
