Patriot Ordnance Factory Roller Cam Pin Upgrade Kit AR-15 223/5.56

The Patriot Ordnance Factory Roller Cam Pin Upgrade Kit is a replacement cam pin and gas key set for AR-15 bolt carrier groups chambered in 223 Remington and 5.56x45mm NATO. The kit is designed to reduce friction between the cam pin and the receiver. Standard cam pins have a square head that drags along the inside of the aluminum receiver, while this kit uses a nickel-plated roller that rolls along the receiver surface.

The kit is sold as a bundle and includes a chrome-plated notched gas key. The roller cam pin has a nickel-plated finish, and the gas key is chrome-plated. The kit is intended for Mil-Spec direct impingement AR-15 bolt carrier groups and is not intended for use with other bolt carrier designs.
