POF USA
Patriot Ordnance Factory (POF-USA) manufactures and distributes law enforcement, military and civilian rifles in Phoenix, Arizona, and was the first manufacturer and seller of gas-piston-operated weapon systems on AR-style rifles in the United States. POF-USA was founded in 2002 by aerospace engineer Frank DeSomma with the intent of solving the most common problems with gas impingement AR15 systems. The company now holds numerous patents and awards for their products.
