AR-15 BCG and charging handle combo — a black nitride bolt carrier group paired with a standard mil-spec charging handle. Drop-in fit for any 5.56 NATO or 300 BLK AR-15 upper receiver. No fitting, no break-in fuss.

The bolt carrier group runs a 9310 steel bolt with a Parkerized (manganese phosphate) finish and a 9310 steel M16-profile carrier with a salt-bath nitride coat. Magnetic particle inspected at the factory — verified free of surface defects before it ships. Properly staked gas key and shot-peened bolt make it ready for sustained fire without break-in.

BCG specs:

• Caliber: 5.56 NATO / .223 Rem / 300 BLK
• Carrier: 9310 steel, M16 profile, salt-bath nitride
• Bolt: 9310 steel, manganese phosphate, MPI tested
• Staked gas key, properly torqued

Charging handle:

• Mil-spec geometry, 7075-T6 aluminum forging
• Anodized matte black finish
• Standard latch — fits any AR-15 upper

This pairing is the cycling heart of any AR-15 build — stripped-upper completion, replacement of a worn or rattling factory BCG, or a budget combo for a first build. Skip the hassle of buying the pieces separately.
