This cam pin, part number INVV-08033, is a standard mil-spec pattern replacement component machined from steel and finished in black, built for AR-15 5.56 NATO and .223 Remington bolt carrier groups. It weighs approximately 0.1 ounces and is supplied with a Phosphate or Nitride finish. Seated through the bolt carrier and into the bolt, the cam pin is the part that links the two together, so it is a worthwhile and inexpensive item to replace when rebuilding a bolt carrier group or refreshing a worn one.
The pin is machined from steel, a durable material for a small part that sees repeated stress with every firing cycle, and it is finished in black for wear and corrosion resistance. Its role is to interface with the bolt and the bolt carrier during cycling, guiding the bolt's movement as the carrier travels rearward and forward. Because it is built to the standard mil-spec pattern, it is intended to drop into a standard AR-15 5.56 bolt carrier group without modification, which makes it a practical choice for builders assembling a new bolt carrier group or replacing a pin that has worn over time.
This cam pin is compatible with standard AR-15 5.56 NATO and .223 Remington bolt carrier groups as a replacement component.
Follow all manufacturer instructions and safe handling practices.
Ensure compliance with all applicable federal, state, and local laws.
