Description
The Lantac E-BCG Enhanced LR-308 is a bolt carrier group for AR-10 pattern rifles chambered in 308 Winchester and 7.62x51mm NATO. The body is machined from 8620 steel and the bolt is made from Carpenter 158 steel, with magnetic particle inspection and a nickel boron finish.
The carrier is QPQ nitride coated, a nitrocarburizing case hardening process that produces a hard, smooth surface with added corrosion resistance and a low coefficient of friction. Its shrouded, forward-facing gas ports are resized to vent gas differently from a standard carrier, which the listing describes as a flatter, smoother energy pulse and a softer start to carrier movement.
The flared tail is intended to steady the carrier's position in the buffer tube during cycling. The group is silver in color.
