Who This Is For
The Luth-AR MBA-2 is ideal for competitive shooters, precision rifle enthusiasts, and AR-10 builders who prefer a solid, fixed-length stock over an adjustable design.

Frequently Asked Questions
Will the MBA-2 kit work on a standard AR-15 lower receiver as well?
The Luth-AR MBA-2 stock itself is compatible with both AR-15 and AR-10 rifle-length A2 buffer tubes. However, this specific kit is configured for .308/AR-10 builds and includes a .308 rifle recoil buffer and corresponding spring. If you are building on a standard 5.56 AR-15 lower, you would need the appropriate AR-15 buffer and spring instead — the MBA-2K308 kit is optimized for the heavier .308 recoil impulse.
How does the MBA-2 differ from the Luth-AR MBA-1 stock?
The MBA-1 is Luth-AR's fully modular, adjustable stock system that allows shooters to customize length of pull, comb height, and butt pad configuration. The MBA-2 is a simplified, fixed-length version that retains the same durable glass-filled nylon construction and sling attachment options but removes the adjustability for shooters who prefer a solid, non-moving stock. The MBA-2 is typically lighter and less complex, making it a great choice for those who have already dialed in their preferred stock position.
Is any gunsmithing or special tooling required to install this stock kit?
The MBA-2 kit is designed for straightforward installation on a standard AR-10 lower receiver with basic armorer's tools. You will need a castle nut wrench to properly torque and stake the A2 buffer tube, and it is recommended to use a receiver vise block for safe handling during assembly. No special gunsmithing skills are required, but familiarity with AR-platform lower assembly is helpful. The kit includes all the internal components — buffer tube, recoil buffer, and spring — so no additional parts are needed to complete the buffer system.
