Timber Creek Outdoors ARBTKFDE AR-15 Mil-Spec Buffer Tube Kit Flat Dark Earth

The Timber Creek Outdoors ARBTKFDE Buffer Tube Kit is a complete drop-in Mil-Spec carbine buffer tube assembly for the AR-15 platform, finished in Flat Dark Earth aluminum.

• Mil-Spec Carbine Buffer Tube - machined to standard carbine length and diameter for drop-in fit on any Mil-Spec AR-15 lower receiver
• Quick Disconnect End Plate - accepts QD sling swivels for fast, push-button sling attachment and removal
• Castle Nut - locks the buffer tube securely into the receiver extension
• Buffer Spring & Pin - completes the assembly so the kit is ready to install out of the box

This kit bundles every component needed to mount a standard carbine stock on a Mil-Spec AR-15 lower receiver, eliminating the need to source parts individually for a new build. The included quick-disconnect end plate gives the builder a built-in mounting point for any QD sling swivel, and the buffer tube itself is machined to standard carbine dimensions for full compatibility with the vast majority of carbine-length stocks on the market.

The Flat Dark Earth finish is matched to the rest of the Timber Creek Outdoors Enforcer and AR accessory line, letting builders maintain a consistent color across a complete build. Whether you're finishing out a stripped lower, replacing worn components, or upgrading an existing carbine, the ARBTKFDE delivers a coordinated, ready-to-install buffer tube assembly for your AR-15.
