Luth-AR MCA 22 Chassis

The new Luth-AR MCA 22 (Modular Chassis Assembly) is manufactured with high-strength, glass-filled nylon polymer, steel and 6061 series aluminum. Its design makes use of a fully adjustable target style stock which is adjustable for both length of pull and comb height in order to optimize the shooter’s alignment with their chosen optical sights and/or riflescopes. 

As a modular chassis, the new Luth-AR MCA 22 fits traditional 10/22-pattern receivers, whether original Ruger parts or aftermarket options. This chassis also has a wide barrel channel that accommodates standard or bull profile barrels without hassle. In addition to the fully adjustable stock, the Luth-AR MCA 22 has a vertical, gooseneck-style pistol grip conducive to prone and positional rifle shooting.
