Product Info for Mitchell Defense Enhanced M16 6mm ARC Bolt Carrier Group

It features a nitride-treated 9310 MPI-inspected bolt for strength, paired with a full-mass 8620 M16 carrier for consistent cycling. The billet extractor with O-ring improves case control, while SP4-coated gas rings reduce friction and increase wear resistance. The gas key is properly torqued and OCKS-staked for maximum retention.
