The Luth-AR MBA-3 adjustable carbine stock fits both mil-spec and commercial-diameter carbine buffer tubes on AR-15 and AR-10 rifles. It fits all .223 and most .308 AR carbine-style rifles, and an included anti-rattle screw locks it tight on either tube diameter.
The MBA-3 is built from glass-filled nylon in black and ships with a medium soft rubber recoil pad. Length of pull, cheek height and butt plate position all adjust, so one stock can be set up for a bench gun, a scoped carbine or a shooter wearing armor.
Features:
Before you order, check whether your buffer tube is mil-spec or commercial. The MBA-3 fits both, but you should set the anti-rattle screw for the tube you have. Install is quick and needs no permanent changes to the rifle.
