Luth-Ar
The Luth-Ar MBA-1 buttstock with .223/5.56 buffer assembly is a complete, ready-to-install fixed stock solution for AR-15 builds running .223 Remington or 5.56 NATO. Built around an A2-pattern buffer system, the MBA-1 arrives as a full kit—buttstock, extension tube, standard buffer, and caliber-matched spring—so you're not hunting down parts across multiple suppliers. If you're building or upgrading an AR lower and want a lightweight, practical buttstock without the premium price tag, this is a no-nonsense choice.
What sets the MBA-1 apart is its adjustability. Length-of-pull and cheek rise both dial in to fit your frame and shooting position, which matters whether you're running a carbine at the range, hunting in layers, or setting up a duty rifle. The modular design means you're not locked into one configuration—tweak it as your kit evolves. The Flat Dark Earth (FDE) finish blends naturally with most modern builds and holds up to field use.
Sling attachment flexibility is built in: molded pockets on the buttstock accommodate Grovtec QD cups (sold separately), and a rail attachment option is available for those who want accessory real estate. It's the kind of practical thinking that separates a good stock from a frustrating one. Assemble it once, dial it in, and move on to actually shooting.
