Lantac CP-R360 AR-15 Domed Cam Pin 5.56 NATO

The Lantac CP-R360 is a domed cam pin with no moving parts. A flat on the front of the head lets it go into a bolt carrier without removing the gas key, and two more flats help cut wear inside the cam channel.

The domed head curves away from the upper receiver instead of leaving a sharp corner to wear against it. The polished head keeps its natural hardened copper/brass color. It works on all mil-spec carriers in 5.56 only.
