The Timber Creek Outdoors Buffer Tube Kit (brand part no. ARBTKRE) gives an AR-15 build everything needed to finish the stock end of the lower in one color-matched package, finished in Timber Creek’s eye-catching Robin’s Egg Blue. Rather than sourcing a buffer tube, end plate, castle nut, buffer, spring, and retaining pin separately, this kit bundles the complete assembly so the rear of the rifle installs in one pass. The quick-disconnect end plate adds a QD sling mounting point at the receiver, a detail that’s easy to miss when building piece by piece.
