Recently received for review is a POF-USA Roller Cam Pin Upgrade kit and modified chrome gas key and fasteners for AR-15/M16 Gas Impingement Rifles. Cost for the kit is $45.

POF-USA

Reduces friction and drag of the bolt carrier.
The roller cam pin rolls as the action moves.
The roller cam pin NP3 coated and the body is Mil-spec hard chrome plated. This allows the pin to operate without the need to lube.


I should have a new bolt carrier arriving shortly and I'll be installing the kit and getting some rounds through it. More information to follow.
