Faxon 5.56 Gunner Lightweight Nitride BCG

The Faxon 5.56 Gunner Lightweight Nitride BCG is a reduced-mass carrier-group option for compatible AR-15 rifles. Its black nitride finish keeps the assembly visually subdued while the Gunner Lightweight carrier reduces mass compared with Faxon's standard M16-profile group. The bolt and carrier arrive as a complete working assembly rather than separate service parts.

Because carrier mass can affect the way a rifle cycles, the Gunner Lightweight configuration should be considered together with the rest of the AR-15 gas and buffer system. The 5.56 NATO bolt face and AR-15 fit should also be matched to the intended barrel and receiver. Headspace and normal cycling should be verified after installation before regular use.

This lightweight Faxon BCG is intended for builders who specifically want the Gunner reduced-mass carrier rather than a standard M16-pattern group. The black nitride finish keeps the visual treatment simple while the carrier profile provides the functional distinction.
