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 (steel) head that grinds along the inside of the aluminum receiver.
Used as a replacement part for our piston Bolt Carrier Groups.
If you want to upgrade to the Roller Cam Pin, you will need to purchase the ROLLER CAM PIN UPGRADE KIT.
