Product Details

Our new BCG is precision machined from 8620 Steel with a shot peened bolt manufactured from Carpenter 158 and Magnetically Particle Inspected. The entire carrier assembly is NiB, Electroless Nickel Boron coated with the patented, advanced UCT EXO process, unlike standard NiB coatings. This offers extreme lubricity with a friction coefficient of .02 and surface hardness of 82-85 Rockwell C. The carriers patented and patent pending design features unique shrouded and forward facing gas ports that have also been re sized so that gas is vented differently to a standard carrier. This results in a system that runs flatter with a smoother energy pulse. In addition the system also runs cooler and cleaner, there is also less pressurization of the upper receiver when running a suppressed barrel. The flared boss at the tail of the carrier enhances the BCG's lock position within the upper and makes it more consistent, resulting in an accuracy improvement. All critical dimensions are hard turned / ground after heat treat and the gas key has been hard chrome lined for the best possible wear resistance. All E-BCG's feature the LANTAC CP-R360 patent pending domed head cam pin that is machined from 17-4PH Stainless Steel and hardened to H900 condition (45RC approx). The ultra smooth head reduces wear within the upper receiver. The BCG's 11.7oz weight helps to increase lock time and smoother operation.Weight 11.7oz Full Auto & Semi-Auto CompatibleForward Porting, enlarged vents.Balanced flared boss.8620 Carrier, Heat Treated, Hard Turned & Ground.MPI Carpenter 158 Bolt, Shot Peened, Hard Turned / Ground.NiB UCT EXO Coating.CP-R360 Domed Cam PinMil-Spec Gas RingsMil-Spec Staked Gas KeyGrade 8 Hardened FastenersAll Hard Chrome surfaces are to MIL-STD-171 1.2.2.2
