LANTAC E-BCG Enhanced Bolt Carrier Group AR-15 223 Remington, 5.56x45mm Titanium Nitride

The LANTAC E-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 treated with a Nitride QPQ process and then TiN coated; Titanium Nitride. This offers extreme lubricity with a friction coefficient of .4 and surface hardness of 80-85 Rockwell C. 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.
