Frequently Asked Questions
Will the MBA-1 Kit fit my standard AR-10 or .308 AR lower receiver?
Yes. The Luth-AR MBA-1 .308 Kit is designed to fit most standard AR-10 and .308 AR-style lower receivers. The included A2 rifle-length buffer tube and integrated receiver end plate are specifically sized for large-frame .308 lowers, and the kit includes all necessary hardware for installation without additional parts.
Can I use this stock if I shoot left-handed?
Absolutely. The MBA-1 is fully ambidextrous. The cheek piece comes pre-installed on the right side for right-handed shooters, but it can be easily repositioned to the left side of the stock to accommodate left-handed shooters — no gunsmithing required.
Is this stock compatible with mil-spec AR-15 buffer tubes or carbine-length setups?
No — the MBA-1 .308 Kit is specifically designed for use with a rifle-length A2 buffer tube (included in the kit) on large-frame .308 AR-10 platforms. It is not intended for mil-spec carbine buffer tubes or standard AR-15 receivers. If you need an MBA-1 for an AR-15, Luth-AR offers a separate AR-15 version of this stock.
