Description

The Lantac Black Nitrided .223/5.56 Enhanced Bolt Carrier Group (E-BCG) is M16 full-auto rated for increase mass and and lock time. The entire carrier assembly is QPQ (Quench Polish Quench) Nitride coated Black, this 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.

Additionally, 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 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. The ultra-smooth head reduces wear within the upper receiver while the E-BCG weight helps increase lock time for 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.
