LANTAC ENHANCED BOLT CARRIER GROUP 762 BLK

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.
