The Luth-AR Modular Buttstock Assembly (MBA) for AR-style rifles replaces the standard buttstock on your AR. The MBA-2 is intended for use with a standard A2 rifle-style buffer tube, offering a low-cost, lightweight, strong, and high-quality option. Unlike MBA-1, MBA-2 does not include extra adjustability. It does not include sling swivels, buffer tube, buffer body, or spring. The MBA-2 is not compatible with carbine/collapsible rifles with telescoping assemblies—use MBA-3 or MBA-4 for those setups.
