LBE Unlimited Mil-Spec Buffer Tube 6-Position AR-15 Gray

The LBE Unlimited Mil-Spec Buffer Tube is a six-position AR-15 carbine receiver extension machined from 7075-T6 aircraft aluminum with a hard-coat anodized Gray finish. Built to mil-spec dimensions with a 1.148 in outer diameter, this buffer tube accepts all standard mil-spec AR-15 buttstocks for a snug, wobble-free fit.

The 6-position design lets the shooter set stock length of pull across six detent positions, accommodating a wide range of body sizes, shooting stances, and gear setups. The Colt Gray anodized finish pairs up well with a factory-style or retro AR-15 build, while the mil-spec diameter ensures broad compatibility across the vast majority of mil-spec carbine stocks on the market.

Manufactured in the USA for an excellent strength-to-weight ratio, the tube threads onto any standard AR-15 lower receiver and is ready for pairing with the appropriate carbine buffer and spring assembly. Whether you are completing a fresh build, replacing a worn tube, or matching a Gray component theme, this is a dependable mil-spec foundation for an AR-15 carbine stock.
