The new Luth-AR MBA-5 brings more features for AR builds.

Randy Luth continues to cast a big shadow in the world of AR-type rifles and accessories. The DPMS founder, after selling the famed rifle company, launched Luth-AR, which has quickly become a leader in rifle components and accessories. Now the Luth-AR MBA-5 buttstock continues that legacy, expanding the company’s extremely popular line of modular buttstocks.

Luth-AR MBA-5 Buttstock

The redesigned MBA-5 buttstock utilizes Luth-AR’s Anti-Rattle set-screw design. It also comes on the original MBA-3 and MBA-4 carbine buttstocks.

The MBA-5 comprises the latest model in the series. It serves as an affordable, lightweight, adjustable carbine buttstock. It comes with a paddle-style adjustment lever, enabling rapid positioning. Meanwhile, a wide, flared cheek rest provides a comfortable cheek weld. Finally, the integrated Picatinny rails allows attachment of a mono-pod or other accessories.

The MBA-5 fits both Mil-Spec or commercial carbine buffer tubes. It accommodates Grovtec Quick Detach sling cup, and works well with Luth-AR’s Chubby rip and Palm Handguard, to complete your build.

The MBA-5 retails for $49.95. For even more info, please visit
