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

Our patented Roller Cam Pin is another 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. As a result, you will never worry about cam slot wear again.
