Luth-AR M4 Buttstock with Rear Sling Swivel

A replacement M4 pattern carbine stock with the rear sling swivel already in place, so a rear sling point does not have to be added later. It slides onto mil-spec carbine buffer tubes and moves through the usual length positions with the release lever underneath.

The body is molded nylon and weighs about 6.9 ounces, which keeps weight off the back end of the rifle. Luth-AR builds it with the waffle sides of the standard M4 stock, so it looks right on a carbine and gives the same cheek weld a shooter already knows. Note that it will not fit commercial diameter tubes.
