We just can't help not accepting the status quo. Bolt carrier groups are available aplenty, but few could meet our exacting standards for performance and value. Seeing "MIL-SPEC" as just the starting point, we set out to ensure the best options are available for our demanding customers.
Improvements include using 9310 tool steel for the bolt, which is stronger and nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical chrome and phosphasted bolt carrier groups. All bolts are fully MPI tested to ensure the material is sound and without defects. Bolt lugs are chamfered 45 degrees to ensure reliable action for even the highest pressure hand loads and fast lightweight actions.
Faxon Bolt Carrier Groups are Superfinished to reduce friction, increase smoothness of operation, and reduce fouling. Further, they are full-Auto rated and maintain the trip for full-auto fire control groups and new multi-stage trigger systems. Gas keys use grade 8 fasteners and are fully staked for a lifetime of service.

First build using Faxon products. I am amazed by fit and finish of BCG barrel and gas block. Finished barrel break in today without failure and accuracy was great from the start. Spent cases all landed within 12 inches of each other. Quality surpasses most of more expensive components I have used in past. Most impressed!
Great BCG with all the necessary features, along with added bonuses that makes this BCG an easy choice for future builds. The right materials in the right places and an attention to Detail often missing at this price point by other competitors. Well over 2000 problem free rounds.
Pros: HIGH QUALITY BUILD LAST, WHICH TO LAST FOREVER!!
I matched this BCG to a 16'' match pencil barrel and the preformance is just as goo as the product looks....perfect!
As with everything made by Faxon, this is a quality BCG. Everything appears to be machined and finished properly. Staking is well done. I expect this BCG will provide excellent service for many years to come.
Purchased with barrel, very pleased, excellent quality
Excellent product product, it is equal to all other out but there bar none.
I love this bolt and how perfectly smooth the coating is. Compared to my TiN bolt it isn't quite as wet or slippery but I know it won't get stained like that bolt will. Only used the bolt a little but it ran great surpressed even dry out of the box. I'm impressed!
I am in the process of building 2 Ars atm, I have purchased this BCG and comparing the fit and finish to a griffin armament BCG, they are very similar in fit and finish. The melonite finish is a little flat in color compared to the one pictured, it is not a gloss finished BCG. Will be firing this soon.
