Patriot Ordnance Factory 00308 Triple Port Muzzle Brake Black Nitride Steel with 1/2"-28 tpi Threads for 223 Rem, 5.56x45mm NATO AR-Platform

The Patriot Ordnance Factory 00308 Triple Port Muzzle Brake is a black nitride steel brake built to tame recoil and manage muzzle rise on your .223 Rem or 5.56x45mm NATO AR-platform rifle. POF engineered this brake with a triple-port design and nitride heat treatment to handle the abuse of rapid fire while keeping your shots on target. If you run an AR with a 1/2"-28 TPI threaded muzzle, this is a serious upgrade over a standard A2 bird cage.

The nitride finish protects against corrosion and wear, and the brake comes complete with a matching collar—everything you need for installation. The three-port layout directs gas upward and to the sides, which works to counteract both recoil impulse and muzzle climb. That means less time getting back on target between shots, whether you're running drills at the range, pushing steel in competition, or working through a training course.

POF's reputation is built on precision and durability, and this muzzle brake reflects that philosophy. It's a no-frills, no-hype piece of gear that does one job well: make your rifle shoot flatter and faster in rapid-fire strings. Pair it with quality ammo and proper technique, and you'll feel the difference immediately.

Frequently Asked Questions

Will this muzzle brake fit my AR-15 or carbine?

Yes, if your barrel is threaded 1/2"-28 TPI and chambered in .223 Rem or 5.56x45mm NATO. POF designed this brake for standard AR-platform rifles in those calibers.

What comes in the box?

The brake arrives with a black nitride-treated collar for installation. No additional hardware is needed beyond what you likely already have for barrel work.

How much does this brake reduce recoil?

We don't have independent recoil reduction figures, but the triple-port design is engineered to manage muzzle impulse and climb in rapid-fire strings. You'll notice softer felt recoil and faster target reacquisition compared to an open muzzle or standard flash hider.

Is the nitride finish durable for everyday shooting?

Yes. POF's nitride heat treatment protects against corrosion and wear, making it suitable for both range and field use.
