❓ FAQs – BCM Bolt Carrier Groups

Q: What’s the difference between an M16 and AR-15 BCG?
The M16 BCG (like BCM’s) has more mass in the rear, which improves durability and recoil impulse. It is 100% compatible with AR-15 rifles.

Q: Is the BCM bolt MPI and HPT tested?
Yes. Each BCM bolt is Magnetic Particle Inspected and High Pressure Tested to meet mil-spec standards.

Q: Will this work in a 5.56 AR pistol?
Absolutely. It’s compatible with all standard AR-15 upper receivers chambered in 5.56/.223.

Q: Can I use this BCG in a suppressed rifle?
Yes. BCM’s chrome-lined carrier interior and staking make it excellent for suppressed setups.

Q: What buffer and spring should I use with this?
For carbine-length systems, a standard H or H2 buffer is recommended for smooth cycling.
