The POF-USA Flash Hider was designed in house by the engineering team at Patriot Ordnance Factory. This muzzle device, available in both .223/.308 configurations does an excellent job at eliminating the large majority of muzzle flash without adding a bulky device to your weapon system. Each device is pre-drilled with a pin hole to make permanently attaching this device much easier should your specific situation call for such action.
