AR MBA-1 Modular Buttstock Assembly for A2 Rifle Buffer Tube – Adjustable LOP & Cheek Riser – Luth-AR

The Luth-AR MBA-1 Modular Buttstock Assembly is a precision-engineered fixed stock designed for AR-15 and AR-10 platforms using a standard A2 rifle-length buffer tube. Lightweight yet rugged, the MBA-1 delivers superior ergonomics and shooter customization with adjustable cheek rise and length of pull (LOP), making it ideal for long-range precision setups.

Constructed from super strong glass-filled nylon, the MBA-1 maintains structural integrity while reducing overall weight. The cheek rest offers an extra 1" of rise, and the extended buttplate gives an additional 1 1/16" of LOP for optimal fit.

This fixed stock integrates seamlessly with .223 and .308 AR-style rifles and includes a compatible A1 buttstock screw for A2 buffer tubes.
