LANTAC ENHANCED BCG 308/7.62 BLACK NITRIDE 01UP762NITEBCG 01-UP-762-NIT-EBCG

LANTAC E-BCG� Enhanced Bolt Carrier Group. - M16 Full Auto Style for increased mass and lock time. - Our 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 Blackthis is a specialized type of Nitrocarbrising Case Hardening that creates a very hard smooth surface with increased corrosion resistance and low coefficient of friction. - The carriers 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 with 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� position within the buffer tube at the time of cycling and makes it more consistent resulting in smoother operation. - 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-H 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 1Lb 2.1oz weight helps to increase lock time and smoother operation. - Gas keys are fitted with gasket sealer & are properly staked at four points and only grade 8 fasteners are used in assembly. - 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. - Weight 1lb 2.1oz - DPMS Gen 1 Pattern Only - Full Auto & Semi-Auto Compatible - Forward Porting enlarged vents. - Balanced flared boss. - 8620 Carrier Heat Treated Hard Turned & Ground. - MPI Carpenter 158 or 9310 Bolt Hard Turned / Ground. - QPQ Nitride Coating - CP-R360 Domed Cam Pin - Mil-Spec Gas Rings - Mil-Spec Staked Gas Key - Grade 8 Hardened Fasteners - All Hard Chrome surfaces are to MIL-STD-171 1.2.2.2 - Shot Peening is conducted with S110 shot Established by Almen Gage A-2 strip .006 -.008 - Lifetime Warranty. - Patented - Made in the USA.
