The Patriot Ordnance Factory Triple Port Muzzle Brake (brand part number 00309) controls muzzle impulse on a .308 Winchester/7.62x51mm NATO AR-10 pattern rifle 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 5/8-24 to fit standard .308 barrels and weighing roughly 0.18 lb, it’s a straightforward upgrade for shooters who want to stay on target through rapid strings of fire on a harder-recoiling caliber than 5.56.
