Luth-AR MBA-4 Carbine Stock Kit

MBA-4 + Cheek Piece is the newest revolutionary designed stock from Luth-AR! This stock is to be paired with Carbine AR rifles to allow shooters to have comfortable and simple adjustability in a light weight package. Not only is it the lightest and most affordable on the market, but it includes several stand-out features. This stock is designed to work with both carbine Commercial and Mil-Spec tubes/assemblies on both the AR-15 and AR-10/.308 platforms as well as any other rifle platform designed to accept a mil-spec or commercial adjustable stock.
