Patriot Ordnance Factory, Roller Cam Pin Assembly, 308, NP3 Coating

POF patented Roller Cam Pin is just one example of how far we will go to reduce friction and drag. Standard AR cam pins feature a square (steel) head that grinds along the inside of the aluminum receiver. Used as a replacement part for our piston Bolt Carrier Groups. This roller cam pin fits the POF P308 (7.62 Model) bolt assembly.
