POF-USA is an American owned and operated small business. Our manufacturing and R&D facilities are headquartered in Glendale, Arizona. POF-USA specialize in the design, manufacturing and marketing of AR style rifles, uppers, lowers and miscellaneous gun accessories.
Welcome to POF-USA Patriot Ordnance Factory, Inc. featuring our P308 and the P415/P416 gas piston rifle systems and accessories. This website is dedicated to America’s Law Enforcement and Military Personnel who are preserving freedom around the world.
POF-USA has engineered, manufactured and tested this system. We are extremely proud of the durability and performance of the P308 and the P415/P416 gas-piston uppers. We have eliminated features of the gas operating system such as gas-rings, gas tube, gas key. The P308 and the P415/P416 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 are the first gas piston operated weapon system on the AR-style rifle platform to sell to the market. All of our weapon systems come standard using C.R.O.S.™ (Corrosion Resistant Operating System), which allows our weapon system to operate without the need of lubricant.
Our fluted barrels using NATO chambers are polygonal rifled, using 4150 Mil-B-11595 chrome-moly vanadium alloy (machine gun rated), to reduce heat and weight. All of our barrels are 70 rockwell case hardened heat treated which are corrosion resistant, and 2X harder then Mil-Spec and hammer forged barrels.
Our gas piston operating system has two modes of fire. One for normal mode of operation and the second mode for suppressed. No tools are required to change modes of operation.
Our heat sink barrel nuts, fluted barrels, and free floating rail design help to reduce heat of the barrel around the chamber throat area of the barrel and the overall operating temperature of the weapon system.
All lowers are ambi-controlled, bolt releases, mag releases, and safety selectors. The billet machined lowers all include oversized intergrated trigger guard for use with gloves and large beveled feed ramps on the entrance of the magwell for fast mag loads.
