LANTAC USA SmoothCam Domed Cam Pin .308/7.62 H - AR-10

The LANTAC USA SmoothCam Domed Cam Pin (CP-R360-H) is a precision drop-in upgrade for the AR-10 platform chambered in .308 Winchester / 7.62 NATO. This small but critical part replaces the standard factory cam pin inside the bolt carrier group, smoothing the cam pin's interaction with the upper receiver and gas key for noticeably cleaner cycling and reduced wear.

The cam pin is CNC machined from 17-4 PH stainless steel and heat-treated to H900 hardness (approximately 45 RC), giving it the strength to outlast the factory part. Its signature domed head is polished to a super-smooth finish so it glides against the upper receiver rails and gas key with far less friction than a flat-headed OEM pin, while the brass / copper-toned dome offers a distinctive visual upgrade on the bolt carrier group.

This "H" (Heavy) variant is dimensioned specifically for .308 / 7.62 AR-10 bolt carrier groups and is not interchangeable with the smaller 5.56 cam pin. Proudly made in the USA by LANTAC USA, it is an easy, no-tools swap that shooters and armorers reach for when building or tuning a precision .308 AR-10.
