The LBE Ar Milspec Buffer Tube Brn is a mil-spec diameter recoil buffer tube designed for AR-15 builds and customization. Built to accommodate any collapsible AR-15 stock that accepts a mil-spec tube, this extension serves as the backbone of your carbine's receiver assembly—whether you're assembling your first rifle, upgrading an existing platform, or stocking a parts drawer for future projects. LBE Unlimited manufactures this component domestically, and the brown finish delivers a classic look that pairs well with a wide range of furniture and finishes.

A quality buffer tube is one of those foundational parts that deserves attention. This mil-spec diameter extension comes pre-threaded and ready to accept your chosen stock, eliminating guesswork and saving time during assembly. The six-position design gives you adjustability to dial in length of pull for comfort and control, whether you're running a carbine for hunting, competition, home defense, or the range.

LBE Unlimited's reputation for domestic manufacturing and attention to detail makes this a solid choice for builders who value reliability in their components. The brown finish resists wear and maintains appearance through regular use, and the mil-spec standard ensures compatibility with the broadest selection of AR-15 collapsible stocks on the market.
