Luth-AR MBA-3F Carbine Buttstock - Flat Dark Earth Glass-Filled Nylon - Fits AR-15/AR-10

The Luth-AR MBA-3F is a fully adjustable carbine buttstock assembly built for AR-15 and AR-10 platforms. Finished in Flat Dark Earth, the MBA-3 replaces a standard carbine-style stock and drops onto both Mil-Spec and Commercial six-position buffer tubes, making it an easy upgrade for any AR carbine in .223/5.56 or .308/7.62x51 NATO.

The MBA-3F body is molded from super-strong glass-filled nylon, keeping the assembly light at 18.5 oz while delivering the rigidity expected from a premium upgrade stock. Overall length is 8.75". The defining feature is the 3-axis adjustable buttplate, which lets the shooter independently dial in length of pull, buttplate height, and lateral offset to match their body geometry and shooting position. The integrated cheek rest offers vertical adjustment to establish a proper cheek weld behind any optic, and an anti-rattle screw locks the stock tight against the buffer tube to eliminate play.

A short Picatinny rail on the underside of the stock provides a clean mounting point for a monopod, sling stud, or other accessories. Installation is straightforward and uses four of the existing carbine buffer tube detent positions, so no additional hardware is required. Whether you are running a patrol AR-15 carbine, a precision AR-10, or a general-purpose AR build, the Luth-AR MBA-3F in FDE delivers the adjustability, durability, and modular fit to dial in any shooter.
