LBE Unlimited AR 308 Barrel Nut – AR-10/LR-308 Pattern Rifles

The LBE Unlimited AR 308 Barrel Nut is a replacement barrel nut designed for AR-10 and LR-308 pattern rifles. This component secures the barrel extension to the upper receiver and provides the mounting surface for free-float handguards. Whether you're replacing a worn nut during a barrel swap or building a custom rifle from scratch, this barrel nut delivers the proper interface for reliable assembly.

Manufactured from steel with a phosphate finish for corrosion resistance, this barrel nut is machined to mil-spec dimensions for consistent fitment. Installation requires a barrel nut wrench, torque wrench, and proper headspace verification—professional installation is recommended if you're not experienced with AR builds. The nut includes standard threads compatible with most aftermarket handguard systems for AR-10 platforms.
