The Enhanced .308 Bolt Carrier Group is precision machined from 8620 Steel with a 9310 precision hard ground bolt. The entire carrier assembly is electroless nickel boron coated for lubricity and corrosion resistance. The carrier design features forward facing gas ports which offers a smoother energy pulse and a system that runs cooler and cleaner with less pressurization of the upper receiver when running a suppressed barrel. The flared boss at the tail of the carrier provides a more consistent lock position within the upper receiver while its 1 lb 2.1 oz weight helps to increase lock time.

The included Domed Cam Pin is machined from 17-4 PH stainless steel, hardened to H900, polished, and finished in its natural hardened coppery state. The circular head has a flat face machined so that it may be inserted into any bolt carrier without removing the gas key. Two further flats are machined at 90 degrees to the front face, minimizing internal wear to the cam channel.
