Toward the beginning of this year, Ares Armor released their first NiB Bollt Carrier Group. This Summer they introduced an improved model with the MK1 Mod0 designation for its new NiB Coating that features a proprietary method of perfecting the balance of the Sodium Borohydride reducing agent. They are also individually coating all components of the bolt carrier group prior to assembly.
As with the original Ares Armor NiB BCG, this is a full auto model manufactured with an 8620 heat treated bolt carrier and a 9310 heat treated steel bolt. The bolt and extractor are shot peened and are MP batch tested with 20% of all product examined. The gas key is properly staked. Crane O Rings are utilized to increase tension on the extractor thus improving overall functionality. Our friends at PredatorArmament.com are now offering the new Mk1Mod0 BCG for $99.
