LANTAC Firing Pin AR-15 6mm ARC Stainless Steel

LANTAC M16 Enhanced Full Auto Style Bolt Carrier Group 6mm Black. M16 Full Auto Style for increased mass and lock time. BCG is precision machined from 8620 steel with a shot peened bolt manufactured from Carpenter 158 or 9310 and Magnetically Particle Inspected. The entire carrier assembly is QPQ (Quench Polish Quench) Nitride coated Black this is a specialized type of Nitrocarbrizing Case Hardening that creates a very hard smooth surface with increased corrosion resistance and low coefficient of friction. The carrier's patented and patent pending design features unique shrouded and forward facing gas ports that have also been resized so that gas is vented differently to a standard carrier. This results in a system that runs flatter with a smoother energy pulse and a softer start to carrier movement. 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. The E-BCG's forward porting and unique shape assist in reducing pressurization inside the upper receiver that can be caused by short barrel rifles running suppressors. However it should be noted that the E-BCG is not a complete solution for this issue and all rifles are different. 'Over Gassed' guns will suffer to a larger extent from this problem.
