LUTH-AR MBA-1 Modular Stock – Black
The LUTH-AR MBA-1 Modular Buttstock Assembly is engineered for shooters who demand precision, comfort, and adjustability from their AR platform. Designed to replace standard fixed A1 or A2 rifle buttstocks, the MBA-1 fits any AR-style rifle equipped with a rifle-length A2 buffer tube. With an advanced modular design and tool-less adjustability, the MBA-1 allows users to fine-tune both the cheek rest height and length of pull to suit their individual shooting style and body mechanics.
Crafted from high-strength, glass-filled nylon, the MBA-1 offers excellent rigidity without excessive weight. The design is fully ambidextrous, allowing it to be used comfortably by both left hand and right hand shooters. The cheek riser is factory-installed for right-hand use but can easily be repositioned for left-hand users, making it ideal for versatile range use or competition setups.
For additional convenience, the MBA-1 features multiple sling attachment points, including molded-in Grovtec QD sling mount pockets (QD cups sold separately). A bottom rail attachment is also available for installing mono-pods or other accessories to further increase stability in prone or benchrest positions. The MBA-1 is available in multiple color options, including Black, Flat Dark Earth, and an optional patriotic Freedom Flag cheek rest.
