The LanTac USA LLC M-SPEC Bolt Carrier Group is a bolt carrier group designed for use in AR10 pattern rifles chambered in 308 Winchester and 7.62 NATO. This bolt carrier group follows M16 style configuration and uses an 8620 steel carrier with a nitride finish for surface hardness and corrosion resistance.

This product is used for cycling and locking the action within compatible large-frame AR platforms.

The LanTac USA LLC M-SPEC Bolt Carrier Group features hard turned and ground components to maintain dimensional consistency under standard operation. In typical setups, the nitride finish provides a uniform black surface with reduced friction characteristics.
