Lantac M-Spec BCG 7.62 Nitride Black

LANTAC E-BCG Enhanced Bolt Carrier Group with TiN coating. - M16 Full Auto Style for increased mass and lock time. - Our new TiN E-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 TiN Titanium Nitride coated. - 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
