Patriot Ordnance Factory .223/5.56NATO Roller Cam Pin Assembly - NP3 Coating

Our patented Roller Cam Pin is just one more example of how far we will go to reduce friction and drag. Standard AR cam pins feature a square head that grinds along the inside of the aluminum receiver.

Used as a replacement part for most piston AR bolt carrier groups.

Note: The 5.56 version fits with all Gas Piston 5.56 carriers, all REVOLUTION carriers, and all ROGUE carriers
