Timber Creek Outdoors ARBTFDE Mil-Spec Buffer Tube for AR Platform - Flat Dark Earth Cerakote Aluminum

The Timber Creek Outdoors ARBTFDE mil-spec buffer tube is a straightforward, no-nonsense component for AR platform rifle builds and repairs. Built to mil-spec dimensions, this aluminum tube accepts standard mil-spec buffer springs and weights, making it a direct replacement or upgrade part for virtually any AR-15 or AR-10 lower receiver that runs a traditional tube-style stock setup. Whether you're assembling a rifle from the ground up, replacing a worn tube, or swapping to a new buttstock, this is the foundation that makes it all work.

Finished in flat dark earth Cerakote, the ARBTFDE delivers durability and corrosion resistance in a color that plays well with modern tactical and hunting builds. Cerakote is a ceramic-based coating that stands up to hard use, solvents, and the elements far better than painted finishes, so you can trust this tube to last through range sessions, field days, and years of maintenance cycles. The flat dark earth hue blends naturally with most handguards, grips, and furniture choices, giving you a cohesive look without fuss.

If you're upgrading an older rifle, replacing a damaged tube, or building an AR from a stripped lower, the Timber Creek ARBTFDE is a reliable, mil-spec choice that doesn't require any special tools or gunsmithing knowledge to install. Pair it with your choice of mil-spec stock, buffer, and spring to complete your setup.
