Our bolt carrier groups are made right here in our shop, to milspec M16 dimensions from the correct 8620 steel for the carrier and 9310 for the bolt.  They are deburred, tumbled, heat treated and receive a final grind to ensure they they meet the print exactly.  The QPQ Black Nitride treatment ensures durability and corrosion resistance.  Our house machined 4140 gas key is finished by H&M for a deep black nitride finish and hydraulically staked to ensure that you gas key screws to not come loose.  Extractors are cut from solid stock, not cast or MIM.
