Luth-AR MBA-4 Carbine Stock with Cheek Riser

The Luth-AR MBA-4 Carbine Stock with Cheek Riser (brand part no. MBA-4-CHP) is a simplified version of Luth-AR’s modular MBA-3 stock for AR-15 and AR-10 shooters who don’t need full adjustability but still want a proper cheek weld. It’s compatible with both Commercial and Mil-Spec diameter carbine buffer tubes, and length of pull adjusts through an anti-rattle screw that engages one of the positions on the buffer tube. This model adds an adjustable cheek rest for a consistent sight picture with a mounted optic, and it keeps the multiple sling attachment points and rear monopod Picatinny rail found on the rest of the MBA lineup.
