The Luth-AR Modular Buttstock Assembly (MBA) for AR style carbines is designed to replace the standard buttstock on your AR. The MBA-3 is designed to work with a 6-position Mil-Spec or Commercial buffer tube. 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.
- Ergonomic Design
- Adapts To Existing Commercial and Mil-Spec Buffer Tubes
- Certain after Market Commercial Buffer Tubes that exceed 1.172″ diameter, may not fit
- The vertical struts for the MBA-3 are fixed, therefore the cheek piece is not reversible like the MBA-1 however the cheek piece itself is designed with a cheek pad for left-handed use
- Caution: the MBA-3 Carbine buttstocks are not designed to be used with Large Bore Calibers such as .338 Lapua or .50 BMG applications. See our MBA-1 and MBA-2 Rifle buttstocks as alternatives.
- The MBA-3 Carbine buttstock is NOT interchangeable with A2 standard buffer tube. You will need to purchase an MBA-1 or MBA-2 Rifle buttstock to fit A2 tubes.
