The LANTAC USA E-BCG (Enhanced Bolt Carrier Group) for the 6mm ARC (Advanced Rifle Cartridge) is a precision-engineered upgrade for your AR-platform rifle. Featuring a special 6ARC-specific bolt and firing pin, this BCG is precision machined from 8620 steel with a shot-peened bolt manufactured from Carpenter 158 or 9310 steel, and is Magnetic Particle Inspected (MPI) for quality assurance. The entire carrier assembly receives a QPQ (Quench Polish Quench) Black Nitride coating - a specialized form of Nitrocarburizing Case Hardening - delivering an extremely hard, smooth surface with outstanding corrosion resistance and a low coefficient of friction. LANTAC's patented design incorporates unique shrouded, forward-facing gas ports that have been resized to vent gas differently than a standard carrier. The result is a system that runs flatter, produces a smoother energy pulse, and delivers a softer start to carrier movement. Designed in an M16 Full Auto style for increased mass and improved lock time, this BCG is built for reliability and superior performance.
