The Luth-Ar MBA-2 Skullaton Rifle Stock in Black delivers a lightweight, ergonomic upgrade for AR-15/AR-10 platforms, crafted from super-strong glass-filled nylon and designed to mount on a standard A2 round tube. This Skullaton fixed stock is compatible with all .223 and most .308 AR style rifles, and it interchanges with standard A2 or A1 buttstocks or any aftermarket stock with an overall length of roughly 10.5 inches, providing a clean, 21st century look and solid feel in the shoulder. It includes an A2 buttstock screw to connect to the A2 standard buffer tube and integrates a castle nut and lock ring for secure, reliable installation, plus easy-to-add enhancements such as a cheek piece that adds 1 inch of cheek-rest height and butt plate assemblies that extend the length of pull by 1 1/16 inches. This stock weighs only 0.7 pounds, is easy to replace, and quick to install, delivering a streamlined silhouette and dependable performance for field, range, or hunting use. Note that carbine/telescoping tube configurations require MBA-3 or MBA-4 solutions.
