LBE Unlimited AR .308 Barrel Nut 

A critical component in any reliable AR .308/AR10 build, the LBE Unlimited AR .308 Barrel Nut is engineered to provide a rock-solid foundation for your barrel assembly. Designed to exacting specifications and crafted from premium materials, this barrel nut ensures secure barrel retention, proper headspacing, and compatibility with standard DPMS-pattern receivers and gas blocks.

Manufactured from 4130 chromoly steel, this barrel nut offers exceptional strength, toughness, and heat resistance. 4130 steel, known for its excellent weldability and fatigue resistance, is a trusted choice in firearm components that endure intense mechanical stress and high temperatures during prolonged firing sessions. This robust material guarantees your barrel remains firmly secured, even under the harshest conditions.

The barrel nut features a phosphate finish that delivers superior corrosion resistance and durability. This coating not only protects the steel from rust and wear but also provides a matte, non-reflective surface that complements the aesthetic of most tactical and hunting rifles. The phosphate finish enhances lubrication retention, making assembly and future maintenance smoother and easier.

Designed specifically for AR .308/AR10 rifles, this barrel nut fits DPMS-style upper receivers and works seamlessly with compatible gas blocks and delta ring assemblies. Whether you’re building a new rifle or replacing a worn barrel nut on an existing build, this component is engineered for precise threading and tight tolerances to ensure a secure, proper fit every time.

Installation is straightforward and compatible with standard AR armorers’ tools, making it a favorite among professional gunsmiths and home builders alike. A properly torqued barrel nut is essential not only for the integrity and accuracy of your rifle but also for safety and reliable function.

As with all LBE Unlimited products, this barrel nut is proudly made in the USA under strict quality control standards. Every part undergoes rigorous inspection to ensure it meets the demands of high-performance rifle builders and enthusiasts who expect nothing less than dependable quality and craftsmanship.
