LBE Unlimited ARCPN AR Parts Cam Pin AR-15/M16 Silver Steel

The LBE Unlimited ARCPN is a replacement cam pin designed for use in AR-15 and M16 bolt carrier groups. Crafted from steel with a distinctive silver finish, this small but critical component ensures the smooth, accurate cam action required for reliable cycling of the bolt carrier group during every firing cycle.

The cam pin rides within the upper receiver and serves as the rotational key that interfaces the bolt and bolt carrier, allowing them to lock, unlock, and rotate in the proper sequence as the rifle is fired. Proper fit and material strength are essential to dependable function, which is why this LBE Unlimited part is machined from steel for the durability and longevity that AR builders and armorers expect.

The ARCPN fits standard AR-15 and M16 pattern bolt carrier groups, making it an ideal replacement for worn or damaged pins during a build, rebuild, or routine parts swap. Made in the USA, this cam pin is built to the quality standards LBE Unlimited is known for across their line of AR parts and accessories.
