Patriot Ordnance Factory 3 Port AR-15 Muzzle Brake

The Patriot Ordnance Triple Port Muzzle Brake includes a steel lock nut to ensure accurate timing and a secure fit. This brake uses three large ports on either to mitigate recoil, with smaller ports on top to reduce muzzle rise. The tip features a five-prong impact fact for obstacles. The lock nut provides reverse tension on the back of the brake to ensure a solid fit that won’t come undone under heavy fire.
