Complete AR-15 BCG — 5.56 NATO / 300 BLK M16 Profile, Phosphate

$252.00

Complete M16-profile bolt carrier group for AR-15 / M4 rifles in 5.56 NATO (.223 Remington) and 300 Blackout (7.62x35mm). Full-auto carrier profile gives the carrier more mass behind the bolt for a more reliable cycling impulse vs. semi-auto profiles — fine for semi-auto rifles, preferred by most builders for duty / range rifles.

Fit: AR-15 / M4 upper receivers chambered in 5.56 NATO or 300 Blackout. ~11 oz assembled weight.

Carrier:

  • Machined from 8620 steel
  • Heavy-phosphate coated
  • Chrome-lined interior
  • Properly staked gas key with grade-8 screws

Bolt:

  • 9310 steel bolt — MIL-SPEC heat-treat and shot-peening
  • Magnetic Particle Inspected (MPI)
  • Chrome-lined gas rings

Drop-in for any standard AR-15 upper. No tuning required for standard gas systems. Pair with a quality charging handle and you have the foundation of a reliable build.
