Extreme Recoil Reduction at an Affordable Price

Taming the recoil of 5.56 tends to be a pretty easy feat – but this muzzle device all but eliminates recoil with an aggressive design to keep you on target.  Similar to more expensive designs on the market, this 3-port muzzle brake/compensator does the same job as many 3-port brakes – dispersing recoil and muzzle blast to either side of the shooter, reducing recoil going into the shooter’s shoulder.  It also compensates through three angled ports in the top of the device, which counteracts recoil by subtly pulling the rifle forward, and pushing it downward.  The result is a device that diminishes muzzle flip and overall force for the shooter, leaving only the momentum of the bolt carrier to deal with.

It’s a great US-made product, includes a crush washer, and is backed by the AT3 Lifetime Warranty.
