MBA-5 Buttstock

The Luth-AR MBA-5 Buttstock is the latest in the MBA Series. Designed as an affordable, lightweight, adjustable carbine buttstock with a paddle-style adjustment lever allowing rapid positioning. The wide flared cheek rest provides a comfortable cheek weld and the integrated Picatinny rail allows for attaching a mono-pod or other accessories.

The MBA-5 requires a Carbine buffer tube, either Mil-Spec or Commercial. Please review the information provided in the Requirements tab below.

The MBA-5 is Grovtec™ Quick Detach sling cup ready*. Paired with our Chubby Grip® and Palm Handguard® the New MBA-5 is just the right choice for your AR.

Note: The MBA-5 is designed with a non-adjustable, flared cheek rest and is not intended to provide vertical adjustment. Order an MBA-3 or add a Cheek Rest Assembly to your MBA-4 for full cheek rest adjust ability on a Carbine buttstock.

Note: Please be advised that Vista Outdoor, LLC – Blackhawk, issued a cease and desist letter to Luth-AR earlier this year. They claim that our clamp mechanism on the MBA-5 violates their patent. It seems rather petty but after review with attorneys and consultation, we decided that it wasn’t worth a battle. Later this year we hope to have the issue resolved with a new design. In the meantime we apologize for any confusion.

Buffer Tube Requirements

The MBA-5 is a Carbine Buttstock and requires the use of a Carbine buffer tube. The MBA-5 will fit either a Mil-Spec or a Commercial buffer tube. (Note: Some commercial buffer tubes may be oversized from industry norms and may not fit. All commercial buffer tubes sold by Luth-AR will fit the MBA-5).

Carbine buffer tubes typically have 6 positions of adjustability, and can be distinguished from an A2 style Rifle buffer tube that offers no adjustment positions. Carbine buffer tubes also differ from the A2 by their shape, the A2 Rifle buffer tube is completely round in shape while the carbine buffer tubes have a rectangular appendage to the tube that encloses six position holes. An A2 Rifle buffer tube is substantially longer than a carbine buffer tube.

Carbine buffer tubes typically are offered in two types, Mil-Spec or Commercial. The Mil-Spec carbine buffer tube is visually identified by the 90 degree “cut” at the closed end of the tube. The Commercial carbine buffer tube is visually identified by the 6 degree slant “cut” at the closed end of the tube. A Mil-Spec tube should meet Military Specifications while Commercial tube dimensions are determined by the manufacturer and are typically made from an extrusion. As long as a Commercial buffer tube does not exceed 1.172″ in diameter the MBA-5 should fit the buffer tube. Using a Commercial buffer tube with an MBA-5 will typically provide a more “snug” fit due to the slightly larger diameter of Commercial buffer tubes.

If you need to purchase a Carbine Buffer tube we offer buffer tubes individually as well as complete kits. We also offer a Scalloped Commercial Buffer tube for that added custom touch for your AR build.
