Patriot Ordinance Factory - Roller Cam Pin Kit - For Direct Impingement AR-15
The Roller Cam Pin lowers friction and smooths operation of the cam pin and the bolt carrier within the upper receiver. This is especially helpful with hard running operating systems since the initial movement of the bolt carrier and cam pin can be quite abrupt. It can also protect the upper receiver from excessive wear from the cam pin. Is beneficial to any AR-15 operating system and especially those that run on the fast side. Cam Pin body is hard chrome plated and roller is NP3 coated. This Kit includes a replacement bolt carrier key with bolts to install on any Direct Impingement Bolt Carrier. This Carrier Key is factory cut to accept the POF Roller Cam Pin that is used on their piston guns and hard chrome plated. The Roller Cam Pin will not fit past the carrier key on most DI guns and this kit allows you to build your carrier the way you want it for your DI gun.
