Luth-AR MBA-1 Buttstock AR-15/AR-10 Black 10.50" OAL Ambidextrous

The Luth-AR MBA-1 is a fixed, modular buttstock assembly purpose-built for the AR-15 and AR-10 platforms. It mounts directly to a standard A1 or A2 rifle-length buffer tube, making it a drop-in replacement for factory A1/A2 stocks as well as most aftermarket options sharing the same overall length. The MBA-1 is molded from glass-filled nylon for a lightweight yet exceptionally strong build, with an assembly weight of just 1.26 lbs.

While the stock fixes solidly to the buffer tube, the MBA-1 incorporates fully adjustable cheek rise and Length-of-Pull adjustment, allowing the shooter to dial in a comfortable, repeatable cheek weld and stock extension for a variety of shooting positions. An ambidextrous design accommodates both right- and left-handed users without modification. The overall length of the assembly is 10.50 inches and the unit ships in a durable black finish.

The MBA-1 fits all .223 Remington / 5.56mm NATO AR-pattern rifles and most .308 Winchester / 7.62mm NATO AR-10-pattern rifles, making it a versatile upgrade for both platforms. Whether you're replacing a worn factory stock or adding ergonomic adjustability to a classic fixed-stock build, the MBA-1 brings modular AR ergonomics to a familiar footprint.
