Faxon Firearms 5.56 M16 BCG Black Nitride – AR-15 Platform

The Faxon Firearms 5.56 M16 BCG delivers reliable cycling and extraction for AR-15 pattern rifles chambered in 5.56 NATO and .223 Remington. This full-auto profile bolt carrier group features proper geometry and staking to ensure consistent performance in carbine and mid-length gas systems. The M16 profile carrier provides additional mass for improved reliability with suppressed or short-barreled uppers.

Finished in black nitride for corrosion resistance and reduced friction, this BCG requires less lubrication than phosphate-coated alternatives. Machined from 8620 steel (carrier) and 9310 steel (bolt), it's magnetic particle inspected and shot-peened for durability. Installation is drop-in for any mil-spec AR-15 upper receiver—simply insert, charge, and function check.
