We are proud to introduce POF-USA's
3.375" long oversized heat sink barrel nut and a silicon nickel plated upper
receiver as options (patent pending). 
POF-USA's gas piston weapon system operates cooler and does not require
oil or lubricant

POF-USA is the only AR-15/M-16 manufacturer to offer these features!

American Vintage Guns and provide you
with a complete POF-USA upper or lower
configurations of any type.  

As a standard feature on POF gas piston weapon systems, each part of the
operating system is hard chrome plated
which makes it easy to clean and maintain. 



Limited Production Run

True Mid-Length Rail - Extra length less weight

P.O.F-USA has engineered an EXCLUSIVE P-415-16-P11SX-CF-223 manufactured and tested this system. We have been amazed by the durability and performance of the POF P-415 Gas-Piston uppers. POF has eliminated features of the Gas Operating System such as gas-rings, gas tube, gas key. The P-415 / P-416 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".

This NEW combination 16" barrel with 11" Predator rail gives you extra length for your custom accessories without the additional weight of the 11" Predator rail system. Not only do you get the space for tactical equipment it also gives a much shorter look to our weapon.
