Patriot Ordnance Factory, Inc. is an American owned and operated small business. Our Manufacturing and R&D facilities are headquartered in Arizona. We specialize in the design, manufacturing and marketing of AR style rifles, uppers, lowers and miscellaneous gun accessories.

POF-USA, Inc. has engineered, manufactured and tested this system. We are extremely proud of the durability and performance of the P-308 and the P-415/P-416 Gas-Piston uppers. We have eliminated features of the Gas Operating System such as gas-rings, gas tube, gas key. The P-308 and the P-415/P-416 Gas-Piston systems also eliminates Heat, Carbon build up and Gas Leaks which can have an adverse effect on the operating system. The biggest issue being “HEAT”. A weapons first priority, must be “RELIABILITY”.

We first displayed our gas piston uppers at the 2004 Shot Show. We have engineered the entire system using standard “AR15/M16” style parts such as the flat top receiver and bolt. We add only three additional parts to operate our gas piston uppers (gas plug, gas piston, and push rod). All uppers come standard with C.R.O.S™
(Corrosion Resistant Operating System).
