Timber Creek Outdoors AR-15 Mil-Spec Carbine Buffer Tube Kit

Everything that goes on behind the lower receiver, in one box. The kit brings a mil-spec carbine buffer tube, a castle nut, a quick disconnect end plate, the buffer spring, and the pin needed for installation.

The end plate is the part worth noting. It has a QD socket built into it, so a push button sling swivel goes right there instead of needing a separate adapter or a clamp on the tube. The tube is mil-spec diameter, which is what the great majority of aftermarket stocks are cut for, so you can bolt on furniture from just about any maker afterward. Finished in black to match a standard AR-15 build.
