Lantac USA Enhanced BCG 308/7.62 Black Nitride AR-10 Bolt Carrier Group

The Lantac USA Enhanced Bolt Carrier Group (E-BCG) is a premium 308 Winchester / 7.62 NATO BCG purpose-built for the AR-10 platform. Designed around the demands of suppressed and high-round-count shooters, the E-BCG delivers a full-auto style carrier with increased mass and unique gas-handling features that set it apart from standard mil-spec offerings.

The carrier is precision machined from 8620 steel and finished in a low-friction Black Nitride coating for excellent wear resistance and lubricity. The bolt is shot peened for fatigue strength and Magnetically Particle Inspected to verify material integrity. Signature E-BCG features include forward-facing gas port vents that help redirect gas away from the shooter when running suppressed, an improved carrier tail for smoother cycling and reduced carrier tilt, and a polished domed cam pin for reduced friction against the upper receiver.

At roughly 11" overall length, the E-BCG drops directly into any standard 308 / 7.62 AR-10 pattern upper receiver. It is engineered as a no-compromise upgrade for builders and end users who want suppressed-friendly performance, durable construction, and the reliability that comes from a properly inspected and finished carrier group.
