Product description
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.

Could I put this on a radical rf-15 that’s multi caliber which shoots 223/556
Da’Shaun Harris · Jun 18, 2026AT3 Support Team — Thanks for reaching out Yes you can
-
Will this work on a 6mm arc with 1/2 x 28 thread?
Mawae · Jun 11, 2026AT3 Support Team — No, a 6mm bullet (.243") is too large to safely pass through the bore of a dedicated 5.56 NATO/.223 (.224") muzzle brake.
-
Will this muzzle break fit the Ruger 556
Vince grippi · Jun 10, 2026AT3 Support Team — Yes, it will fit a standard Ruger AR-556 perfectly since they share the same 1/2x28 thread pitch and 5.56 caliber.
-
Will this work on PSA guardsman
Anthony · Dec 29, 2025AT3 Support Team — Yes, the AT3™ AR-15 3-Port Muzzle Brake with Crush Washer (1/2×28 threads) will work on PSA Guardsman rifles chambered in 5.56/.223, as those models use the standard 1/2×28 muzzle threading.
