The Patriot Ordnance Factory Triple Port Muzzle Brake (brand part number 00308) controls muzzle impulse on a .223 Remington/5.56x45mm NATO AR-15 for a noticeably softer felt recoil and faster follow-up shots. POF heat treats the brake with a black nitride finish for corrosion resistance and wear durability, then pairs it with a matching nitride-treated collar and five strike prongs that help redirect propellant gas for muzzle control. Threaded 1/2-28 to fit standard 5.56 barrels, it’s a straightforward upgrade for shooters who want to stay on target through rapid strings of fire, whether that’s a competition stage or a follow-up shot on a moving target.
