AR MBA-3 Fully Adjustable Carbine Buttstock – 6-Position Tube Compatible – Luth-AR

The Luth-AR MBA-3 Carbine Buttstock offers rugged adjustability and tactical functionality for AR-15 and AR-10 carbines using either mil-spec or commercial 6-position buffer tubes. Designed with precision and ergonomics in mind, the MBA-3 delivers 1″ of cheek rise adjustment and 3-axis buttplate movement for total shooter comfort and control.

The MBA-3 stock uses 4 of the 6 positions on your buffer tube and includes a built-in Picatinny rail for monopods or sling mounts. A set screw eliminates the rattle common with collapsible stocks, allowing you to lock it in your preferred shooting position. Whether you're running a .223 or .308 AR platform, this stock brings modularity and durability without the weight.

For A2 rifle-length setups, check out the Luth-AR MBA-1 Modular Buttstock Assembly.
