Luth-AR MBA-4F Skullaton Carbine Stock Assembly – Flat Dark Earth

The Luth-AR MBA-4F Skullaton is a carbine buttstock assembly offered in Flat Dark Earth. It is constructed from glass-filled nylon and weighs 9.5 ounces.

The MBA-4F is designed to mount on mil-spec or commercial buffer tubes and uses 4 of the 6 available positions on the tube. It is compatible with commercial and mil-spec buffer tubes; however, after-market commercial buffer tubes exceeding 1.1172 inches in diameter may not fit. This stock is not compatible with the A2 standard buffer tube.

The MBA-4F fits .223 and most .308 AR carbine-style rifles. It is not designed for large-bore calibers such as .338 Lapua or .50 BMG. For those applications, Luth-AR recommends the MBA-1 or MBA-2 rifle buttstocks.
