Luth-AR MBA-4 Carbine Buttstock w/ Cheek Riser - Black Glass Filled Nylon AR-15/AR-10

The Luth-AR MBA-4 Carbine Buttstock with Cheek Riser is a direct replacement for the standard adjustable stock on AR-15 and AR-10 platform carbines chambered in .223 Remington and .308 Winchester. The MBA-4-CHP variant adds an integrated adjustable cheek rest for a more comfortable and consistent cheek weld behind the optic.

Built around a strong, skeletonized glass-filled nylon body in a matte black finish, the MBA-4 keeps weight low while holding up to hard field use. The stock slides onto any 6-position Mil-Spec or Commercial-spec carbine buffer tube with no extra hardware, making installation a true drop-in affair.

Designed to give AR-platform shooters a more refined fit, better cheek contact, and a cleaner overall look, the MBA-4 is a cost-effective upgrade over a factory adjustable carbine stock and an easy way to modernize any AR build.
