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.
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.
Frank DeSomma is President and CEO of POF-USA. Frank has 28 years experience in an industry most recognized for precision, quality, and reliability, the Aerospace Industry. His success in the manufacturing business is based on his skill and experience in troubleshooting faulty equipment and design engineering. As a sport shooter and lifelong student of quality and precision, Frank decided to embark on a voyage to improve the traditional gas impingement design for the AR-style rifle. In just four short years, Frank has been able to inject his dedication for perfection into the main stream firearms industry.
We are the first gas piston operated weapon system on the AR-style rifle platform to sell to the market.
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.
