Luth-AR MBA-3 Carbine Buttstock Flat Dark Earth$150.35
Availability: In Stock
The Luth-AR MBA-4 Carbine Buttstock with Cheek Rest is a practical upgrade for any AR-15 or AR-pattern carbine running a standard buffer tube. If you're running irons, a red dot, or a magnified scope on your carbine, a proper cheek weld matters—and the MBA-4's adjustable cheek rise lets you dial in the height that works for your setup and your shooting position. It's a direct swap for a factory adjustable stock, designed to be lightweight, durable, and strong without the premium price tag of boutique options.
The MBA-4 works with both Mil-Spec and Commercial carbine buffer tubes, so you don't need to replace your buffer assembly. The modular design means you can configure sling attachments, add a monopod via the built-in rail, and lock everything down with the anti-rattle set screw to keep your setup quiet on the move or at the bench. Multiple sling attachment points—including molded pockets sized for Grovtec QD cups (sold separately)—give you real flexibility for hunting, tactical training, or range use.
Whether you're fine-tuning a precision rifle build or just tired of your factory stock feeling wrong behind your optic, the MBA-4 delivers solid ergonomics and modularity at a price that won't break the budget.

The MBA-4 features an anti-rattle set screw that locks the stock securely in place, minimizing movement and noise.
