The Luth-AR MBA-5 Buttstock & Chubby Grip Black package brings together a lightweight, adjustable carbine buttstock and an ergonomic pistol grip for AR-15 platforms. The MBA-5 buttstock uses a paddle-style adjustment lever for quick length-of-pull changes, a wide flared cheek rest for a stable cheek weld, and an integrated Picatinny rail for mounting a monopod or other accessories. An anti-rattle set screw lets you fine-tune the fit on Mil-Spec or commercial carbine buffer tubes, while the Chubby Grip is shaped with a full palm swell, thumb rest, and palm shelf to lock the hand in place and improve trigger control.

This combination is well suited for AR-15 owners looking to refine comfort and control for range use, training, or competition-focused shooting. The fixed flared cheek rest and contoured grip help promote consistent head position and repeatable hand placement, supporting more precise shot-to-shot performance. With thoughtful ergonomics and practical adjustability, this Luth-AR set reflects the manufacturer’s focus on shooter-friendly design and functional innovation.
