ReeceDOA's Review of Faxon Firearms 458/ 450 M16 Bolt Carrier Group
Top-tier machining from the jump. Bolt face, lugs, and carrier interior are cut clean with tight, consistent tolerances — no tooling marks, no slop in the carrier. Everything indexes exactly like it should.
The coating is the real story. Ran 500 rounds through it with a forced-reset trigger driving a high cyclic rate, and the finish has held up to the heat and pressure without a single issue — no flaking, no galling, no discoloration past normal. Wear patterns at 500 are minimal and exactly where you’d expect them: light contact polishing on the lugs and rails, nothing premature or out of place.
Function has been flawless. This thing runs slick straight out of the package and stays that way even when it’s running hot and dirty. Lockup is consistent, extraction is positive, and it doesn’t get sluggish as the round count climbs.
If you want a large-bore BCG that’s machined to a high standard and finished to survive abuse, this is it. No notes. Buy with confidence.
