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.

    This stock does not properly fit a milspec buffer tube it is super loose and rattles worse then any stock I’ve ever used of course I didn’t know until after I installed it so I guess I’m stuck with it the adjustment lever is cheap feeling and makes a ton of noise a $40 magpul is much better

  • Excellent stock

    The reason for the 3 star is because I ordered a commercial stock but instead received a mil spec stock. Was very disappointed and did not bother to reach out because I can use it with my other firearms. This stock was suppose to be for my RIA VR80 shotgun. Was very excited to receive the stock but only to find out it did not fit properly. Disappointing....
