MBA-3 Adjustable Carbine Buttstock

MBA-3 Adjustable Carbine Buttstock

The Luth-AR Modular Buttstock Assembly (MBA) for AR style carbines is designed to replace the standard buttstock on your AR. It fits onto the standard 6-position buffer tube (Mil-Spec or Commercial). The MBA-3 features a 3-Axis Buttplate with Length-of-Pull adjustment as well as height and lateral adjustments, and an adjustable cheek rise in a low-cost, lightweight, strong and high-quality design.

The MBA-3 requires a Carbine buffer tube, either Mil-Spec or Commercial. This stock works with both carbine Commercial and Mil-Spec tubes/assemblies.

The MBA-3 also features an anti-rattle set screw. The modular design of the MBA Buttstock allows you to configure your buttstock to your specific and personal needs. Includes a rail attachment for attaching a monopod. The MBA features multiple attachment points for a sling, including molded pockets that will accept Grovtec QD cups, sold separately.

Fits Commercial OR Milspec Buffer Tubes: Either one will work with your MBA-3 Carbine buttstock, however Commercial buffer tubes are typically larger in diameter than Mil-Spec buffer tubes. The MBA Carbine Buttstocks will have more free-play on the Mil-Spec tubes than Commercial tubes. There is an anti-rattle set screw designed to tighten up the buttstock when used with a Mil-Spec buffer tube. The anti-rattle set screw should only be snugged up just enough to remove the free-play. Do not over tighten as that will damage the buttstock.
