Patriot Ordnance Factory Roller Cam Pin Upgrade Kit 223 Rem/5.56x45mm NATO AR-Platform 00393

The Roller Cam Pin Upgrade Kit comes complete with a notched gas key for Mil-Spec direct impingement bolt carriers.

POF’s patented Roller Cam Pin is another example of how far they will go to reduce friction and drag. Standard AR cam pins feature a square head that grinds along the inside of the aluminum receiver. As a result, you will never worry about cam slot wear again.
