Luth-AR MBA-3 Carbine Buttstock Assembly Black, Adjustable Cheek Rest & 3-Axis Buttplate

The Luth-AR MBA-3 is a black, adjustable carbine buttstock assembly for AR-style rifles, designed to mount on a 6-position carbine buffer tube. It is made from strong, lightweight glass-filled nylon and is intended to replace standard adjustable carbine stocks on AR-15 and AR-10/.308 carbine platforms. The MBA-3 provides an adjustable cheek rest adding up to 1 inch of height, a 3-axis buttplate that offers an additional 1-1/16 inch of length-of-pull plus vertical and lateral adjustment, and a medium rubber recoil pad installed on the buttplate. The stock includes a bottom Picatinny rail for attaching a monopod, multiple sling attachment points with molded pockets that accept Grovtec QD cups (sold separately), and a flat-bottom index set screw designed to reduce rattle and secure the stock in a preferred position. Overall weight is approximately 18.5 ounces.
