Manufactured by our finest domestic, Mil-Spec contractors these are among the best AR rifle bolts on the market and the same bolt carrier groups we use as the basis of our renowned custom rifles!
The bolt is precision machined from aerospace grade 9310 tool steel, shot peened for increased strength and includes a tool steel extractor and ejector, appropriate extractor spring, and is MPI (Magnetic Particle Inspected) and randomly batch HPT (High Pressure Tested).
The extractor is 4140 gun quality, annealed, cold drawn steel per the Mil-Spec.
With a complete Black Nitride finish, the 8620 steel carrier includes a proper machined Mil-Spec gas key secured to the carrier via Grade 8 fasteners and properly staked in our shop during final inspection.
The super hard Black Nitride Finish is an advanced, lower friction surface treatment that minimizes the need for excessive lubricants and cleaning and will look like new for years and will never peel, flake or chip.
These precisely machined, finished and hardened parts will ensure long term proper gas system functioning and reliability.
All experienced AR shooters know that the best spare parts kit for an AR-15 rifle is a spare complete bolt carrier assembly!
NOTE- The only difference between “semi-auto” and “full-auto” carriers are the carrier weight and external profile. The “full-auto” carrier is slightly heavier to provide more mass and lower cyclic rate that can benefit carbine length and shorter gas systems, short barreled/suppressed rifles and machine guns. The “semi-auto” carrier is slightly lighter to provide the least amount of recoil impulse for rifle length gas systems and it’s design makes reinstalling the firing pin easier after cleaning.
Both carrier types are considered completely interchangeable and there are no restrictions on the ownership of a “full auto” carrier group in a semi-automatic rifle.

- Bolt material is aerospace grade 9310 MPI inspected

Perfect match
Super nice BCG, perfect match for the Wilson barrel I just bought.
USWOW!! This looks AMAZING
I received this BCG expecting just another typical off the shelf BCG. Let me tell you, This thing is Beautiful! I almost don't want to use it and just place it on display. the quality of the workmanship really shows.
USGreat
It was great. The item got here fast. Tried it out and all is good. No problems great service.
USSlick
Wilson Combat has a reputation of being a very high quality company with high quality parts. The machining is great and NicBoron coating makes for super smooth cycling. Only have just under 200rds through it so far but can tell this is a BCG that will last. Only downside is how dirty it gets while running suppressed but that’s any NiCBo coating
USExcellent fit and quality
Clean. Smooth. Very nice and a good deal at AR15discounts. I’ll be buying more.
