Luth-AR MBA-3 Modular Stock for Mil-Spec or Commercial AR-15 Buffer Tubes

Fully Adjustable AR-15 Buttstock for Mil-Spec or Commercial Buffer Tubes

The MBA-3 Buttstock replaces the standard stock on your AR, with complete adjustment for cheek weld, length of pull, and features a 3-axis buttplate. This stock fits onto carbine buffer tubes, whether using the mil-spec or commercial diameter – meaning it fits on basically any AR rifle with a six position tube. This stock is also rattle free, with adjustable tension on top of getting perfect alignment with your optics.

If you’re starting a new build, be sure to pick up a mil-spec buffer tube kit with everything your recoil system needs!

Features
