Luth-AR MBA-1 Standard .223 Adjustable Stock Kit, Black

The Luth-AR MBA-1 Standard .223 Stock Assembly Kit (brand part no. MBA-1K) is a complete, Mil-Spec adjustable stock package built for .223/5.56 AR-15 builds. Rather than a bare buttstock alone, this kit bundles what’s needed to get a functional, adjustable stock onto a Mil-Spec receiver extension, saving builders from tracking down individual small parts. The black finish is a clean match for most factory and aftermarket AR-15 furniture, and the adjustable design lets shooters dial in length of pull for their stance, body armor, or optic setup.
