LBE Unlimited .308 Bolt Carrier Group – AR-10 Platform

The LBE Unlimited .308 Bolt Carrier Group is a replacement or spare BCG for AR-10 pattern rifles chambered in .308 Winchester/7.62x51 NATO. This component handles the critical functions of chambering, firing, extracting, and ejecting cartridges in your large-frame AR platform. Keeping a spare BCG on hand ensures you can maintain your rifle's reliability during high-volume shooting or if your primary BCG requires cleaning, inspection, or replacement.

Constructed from machined steel with a phosphate finish for corrosion resistance and reduced friction, this BCG is designed as a direct replacement for standard AR-10 bolt carrier groups. Installation is straightforward for anyone familiar with AR-pattern rifle maintenance—no gunsmithing required. The carrier includes a properly staked gas key and an assembled bolt with extractor and ejector installed.
