Luth Ar Mba-2 Stock Kit 308

The Luth-AR MBA-2 Stock Kit for .308/7.62 is a complete buttstock assembly designed to retrofit AR-10 lower receivers with a functional A2-style buffer system. This fixed stock kit delivers a field-proven alternative to adjustable stocks, offering shooters a lightweight, cost-effective solution for building or upgrading .308 AR platforms. The MBA-2 combines simplicity with reliability—essential attributes for duty rifles, competition builds, and training carbines where stock performance directly impacts recoil management and shooter control.

This complete kit includes everything required for assembly: the MBA-2 fixed buttstock itself, a standard A2-style buffer extension tube, a .308/7.62-caliber buffer, and the corresponding buffer spring matched to the larger cartridge's recoil impulse. The fixed design eliminates the wobble and rattle associated with loose collapsible stocks and removes a potential mechanical failure point. Weighing 1.69 lbs for the entire assembly, the MBA-2 adds minimal weight to the platform while maintaining the structural rigidity operators depend on during sustained fire or duty transitions. The straightforward design means faster assembly, easier maintenance, and no adjustability learning curve—particularly valuable in high-stress environments where consistency matters.

The MBA-2 .308 kit suits AR-10 builders seeking reliable stock functionality without premium pricing. Law enforcement and military units evaluating fixed-stock configurations for standardization, private security teams managing fleet rifles, and precision rifle enthusiasts prioritizing recoil stability all benefit from this complete, ready-to-assemble package. The fixed stock design also appeals to shooters in restricted jurisdictions where adjustable stocks face regulatory scrutiny, making the MBA-2 a straightforward compliance-friendly option. Installation is straightforward for anyone with basic gunsmithing familiarity—no specialized tools or advanced technical knowledge required.
