Luth-AR MBA-1 Rifle-Length Fixed Stock, Black

The Luth-AR MBA-1 is a rifle-length, fixed buttstock assembly designed for AR-style rifles using a rifle-length A2 buffer tube. It provides fully ambidextrous operation and an adjustable cheek piece that moves both vertically and fore/aft for shooter fit. Length of pull is user-adjustable via a thumbscrew, and the assembly incorporates a receiver end plate along with a castle nut and lock ring. The stock is molded from durable glass-filled nylon and is supplied as a fixed rifle-length unit rather than a carbine-style collapsible stock.
