High Performance 308 Bolt Carrier Group is Ideal Upgrade for Your Favorite AR10
The Lantac E-BCG, Enhanced Bolt Carrier Group is M16 Full Auto Style for increased mass and lock time. It 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 very hard, smooth surface with increased corrosion resistance and low coefficient of friction. The carriers patented 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.

All E-BCG's feature the LANTAC CP-R360-H domed head cam pin that is machined from 17-4PH Stainless Steel and hardened to H900 condition. This ultra smooth head reduces wear within the upper receiver.

In addition the system also runs cooler and cleaner with 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.
