The Faxon 5.56 M16 BCG is a mil-spec bolt carrier group engineered for shooters building or upgrading AR-platform rifles in 5.56 NATO. Built from 9310 tool steel and heat-treated to military specifications, this is a no-compromise internal component designed to pair seamlessly with other mil-spec parts and deliver reliable operation across thousands of rounds. Whether you're assembling a precision rifle, a duty-ready carbine, or a range workhorse, a quality bolt carrier group is the foundation everything else depends on—and Faxon's reputation in the precision firearms space means you're starting with a solid one.
The M16 profile of this BCG is fully compatible with full-auto capable lowers, and the forward assist serrations are cut to work smoothly with your upper receiver. Faxon machines each carrier with care: chamfering is added to the rear of the locking lugs to reduce wear and support reliable feeding and extraction under harsh conditions. The bolt and carrier are salt-bath Nitride treated for corrosion resistance and extended service life, and every unit undergoes magnetic particle inspection to catch defects before they reach your safe. All the ancillary parts come pre-installed—spring, insert, and Crane O-ring—so you can drop this BCG into your upper and get to the range.
If you're the type who takes rifle reliability seriously, the Faxon 5.56 M16 BCG rewards that attention with consistent, predictable performance. It's not the cheapest BCG on the shelf, and it shouldn't be—this is a part that cycles thousands of times and absorbs shock and wear. Faxon built this one right.
| Caliber | 5.56 NATO |
| BCG Profile | M16 |
| Material | 9310 Tool Steel |
| Finish | Salt-Bath Nitride, All-Black |

Yes. The Faxon M16 BCG is mil-spec and will work with standard AR-15 uppers. The forward assist serrations are cut to engage properly with your upper's forward assist.
Yes. The bolt carrier group ships with the spring, insert, and Crane O-ring already installed, so you can drop it directly into your upper receiver.
The M16 profile is compatible with full-auto capable lowers. If you're building on a standard civilian semi-auto lower, this BCG will function normally and reliably.
The salt-bath Nitride finish provides superior corrosion resistance and hardness compared to standard coatings, extending the service life of the carrier and bolt through thousands of firing cycles and across harsh environments.
