Manufactured by our finest domestic Mil-Spec contractors these are among the best 5.56 AR rifle bolts on the market and the same bolts we use as the basis of our renowned custom rifles!
Our bolt is precision machined from Carpenter No. 158 steel, shot peened for increased strength and a 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
Parkerized externally and internally chrome lined the 8620 steel carrier includes a proper machined Mil-Spec gas key that is chrome lined, phosphated and heat treated per GI specifications. It is secured to the carrier via Grade 8 fasteners and properly staked in our shop during final inspection.
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 machineguns. 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.

|Ive been looking for a quality BCA and this is the best Ive found for the price.|
|Great Looking BCG||4/2/2014|
|Received mine in the mail as a spare for my AR-15 and very pleased. First thing I did was to break it down and clean and lube it and do a visual check and was very impressed by the excellent workmanship and extra happy with the sale price Wilson had on it and couldnt pass on that deal. Now I got to go to the range and test it out.|

|The BCG came in yesterday and took it to the range and fired everything from steel to brass and not a single problem. Staking was amazing and head space was right on the money. I would not hesitate to buy from Wilson as you get Wilson guarantee and quality.|

|I was a little weary purchasing this mostly due to the incredible sale price. Upon arrival, i tore it down. I was very impressed. Incredible deal. MPI marked bolt, high quality parts and finish. Do not pass this deal up, you will not regret it.|

|Good to go!||10/22/2013|
|I bought this for my m16A4 clone build. Fit perfectly in a BCM 20 government profile upper. I preferred this over a BCM BCG because I dont like markings/laser engraved logos on my BCGs. So far, Ive shot 100 rounds of .223 55 gr. and it has functioned 100%. After comparing this to my Colt BCG, I can say that the build quality is great. The gas key is properly staked very similar staking to Colts, parkerized finish is done well, Chrome lining in the key and inside the carrier is done well also. The only downside is that theres no MPI mark on the bolt. However, if Wilson Combat says these are MPId and HP tested, i trust them. Good to go!|
