Item # 145202 Style LNT-01-UP-556-NIT-EBCG UPC 712038709168 Condition New Manufacturer [Lantac](https://www.kygunco.com/brand/lantac) Weight 3 lb ### Lantac Enhanced BCG Full Auto Style .223/5.56 Blk Nitride M16 Full Auto Style for increased mass and lock time. This 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 QPQ (Quench Polish Quench) Nitride coated Black, this is a specialized type of Nitrocarbrising Case Hardening that creates a vary 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 is 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 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. 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. **SPECIFICATIONS** - Weight 11.7oz - Full Auto & Semi-Auto Compatible - Forward Porting, enlarged vents - Balanced flared boss - 8620 Carrier, Heat Treated, Hard Turned & Ground - MPI Carpenter 158 Bolt, Shot Peened, 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 ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
