Luth-Ar MBA-3 Carbine Stock FDE Adjustable Cheek Rest AR-15 AR-10

The Luth-Ar MBA-3 Carbine Stock in Flat Dark Earth delivers a fully adjustable, ergonomic carbine buttstock assembly designed to mount to a carbine rifle with a 6-position mil-spec or commercial tube, offering compatibility with AR-15/AR-10 platforms and a total weight of about 18.5 ounces for a lighter, responsive feel. This stock features an added height cheek rest and a three-axis adjustable butt plate assembly that extends the length of pull by 1 1/16 inch, with horizontal, vertical, and lateral adjustments to fine-tune the fit to your shoulder and shooting stance, while the fixed vertical struts preserve a reliable cheek piece for left-handed use. The MBA-3 also includes a Picatinny rail along the bottom rear of the stock body to attach your choice of accessories and a flat bottom index set screw (10-24) to eliminate rattle and lock the stock securely in your preferred position. Constructed from super-strong glass-filled nylon, it is designed to adapt to existing commercial and mil-spec buffer tubes and is compatible with most .223 AR carbines and many .308 AR variants, though certain aftermarket tubes exceeding 1.172 inches in diameter may not fit. The Black model comes with a medium soft rubber recoil pad, while the FDE version uses a hard butt plate as a pad; both options balance comfort and control, and the MBA-3 is interoperable with the MBA-1 family for continued versatility.
