The LBE Unlimited AR .308 Barrel Nut provides a secure foundation for barrel assembly in AR .308/AR10 builds. Constructed from 4130 chromoly steel with a phosphate finish, this material offers excellent weldability and fatigue resistance, making it suitable for firearm components subject to intense mechanical stress and high temperatures.
Designed for AR .308/AR10 rifles, this barrel nut is compatible with DPMS-style upper receivers and works with compatible gas blocks and delta ring assemblies. It ensures secure barrel retention, proper headspacing, and compatibility with standard DPMS-pattern receivers and gas blocks. Installation uses standard AR armorers’ tools.
Made in the USA under strict quality control standards, every part is inspected to meet the standards expected by rifle builders and enthusiasts. Proper torquing of the barrel nut is essential for rifle integrity, accuracy, safety, and reliable function.
