Manufacturer's of Quality, "Regulated Short Stroke Gas Piston Weapon Systems" since 2004.
The first M16/AR15 type and AR10 type weapon systems offered on the market being piston driven.
All of our weapon system operate with and without the need of Lube, using C.R.O.S. (Corrosion Resistant Operating System).
We offer "Relentless Reliability" on all our weapon systems.
We believe in "Quality over Quantity".

POF-USA has engineered, manufactured and tested this system. We are extremely proud of the durability and performance of the P308 and 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 P415/P416 Gas-Piston system 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".
POF-USA 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), which allows our weapon system to operate without the need of lubricant.
