POF USA Roller Cam Pin Upgrade Kit
Ratings & Reviews
Outstanding not an AR gimic
These roller cam pins are being used in piston rifles & our special forces units are using them with outstanding results. The gas key is NP3 coated & combined with a nickel boron or fail zero, NP3+ BCG your rifle will fire longer under the worst & most dirty conditions as a roller cam has a lot less friction than a rectangle cam pin. Try it you won't be disappointed.6 years military police investigator 3 years training to guard generals 3 years guarding generals, competitive state & national shooter, been through police academy so I have some experience with firearms.
