When you need an adjustable AR stock for your next build, the Luth-AR MBA-5 AR buttstock may be the piece of your dreams. This is just the latest in the Luth-AR MBA series. The MBA series brings you quality features that you might expect in a much more expensive buttstock, making it a great addition to the Wing Tactical catalog.

Easy Adjustment

The Luth-AR MBA-5 AR buttstock is simple to use. The paddle lever that operates the stock length adjustment is easy to move and operates intuitively, keeping you engaged with your environment even as you make crucial adjustments.

Functional Features At A Great Value

The Luth-AR MBA-5 AR stock features a nice broad cheek rest for a solid cheek weld. That gives the shooter great stability whether he chooses to use the integrated Picatinny rail to add on a rear monopod. It’s QD ready so you can make the changes you want on the fly.
