The MBA-1 Fixed Rifle Modular Stock Assembly for AR-style rifles replaces the standard A2 buttstock with a lightweight, durable option. It is compatible with standard A2 rifle-style buffer tubes and includes Length-of-Pull (LOP) and cheek rise adjustments. It features multiple sling attachment points, including molded pockets that accept Grovtec QD cups (sold separately, part# 593-000-038), and offers optional rail attachment compatibility. It is interchangeable with standard A1 or A2 buttstocks and most aftermarket buttstocks approximately 10.5 in overall length. However, it is not compatible with carbine/collapsible rifles using 6-position buffer tubes; MBA-3 or MBA-4 are required for those platforms. Fully ambidextrous, the MBA-1 allows the cheek piece to be installed on either side and adjusted both vertically and horizontally for a tailored fit. Weight 18.4 oz, and it provides a Length-of-Pull range from 10.5 to 11.5 in.
