Available in Black or Flat Dark Earth
Includes:
The Luth-AR Modular Buttstock Assembly (MBA) for AR style carbines is designed to replace the standard buttstock on your AR. The MBA-4 is designed to work with a 6-position Mil-Spec or Commercial buffer tube. The MBA-4 is a direct replacement a standard adjustable carbine buttstock without additional Length-of-Pull or Cheek rise in a low-cost, lightweight, strong and high-quality design.
The MBA-4 requires a Carbine buffer tube, either Mil-Spec or Commercial. Please review the information provided in the Requirements tab. This stock works with both carbine Commercial and Mil-Spec tubes/assemblies.
The MBA-4 also features an anti-rattle set screw. The modular design of the MBA Buttstock allows you to configure your buttstock to your specific and personal needs. The MBA features multiple attachment points for a sling, including molded pockets that will accept Grovtec QD cups, sold separately. Available in Black or Flat Dark Earth.
The Wing Grip™ is our ambidextrous grip that is designed with shooter ergonomics in mind. The full palm swells fill the hand, providing a consistent and rapid grip, properly positioned to promote accurate and repeatable shots on target. The thumb rests and palm shelfs work together to lock the hand in place shot after shot, while the raised trigger finger surface, forces the finger into the proper curved position for better trigger control and comfort. Available in either Black or Flat Dark Earth.

The MBA-3, MBA-4 and MBA-5 Buttstocks require the use of a Carbine buffer tube. Use the diagram below to determine if you currently have an Carbine buffer tube. If you have an A2 Rifle buffer tube you may want to look at the MBA-1 or MBA-2 buttstock. If you are ordering an MBA buttstock kit, the proper buffer tube is included.

Further you will want to determine whether your buffer tube is a Mil-Spec or Commercial buffer tube.
Either one will work with your MBA Carbine buttstock, however Commercial buffer tubes are typically larger in diameter than Mil-Spec buffer tubes. The MBA Carbine Buttstocks will have more free-play on the Mil-Spec tubes than Commercial tubes. There is an anti-rattle set screw designed to tighten up the buttstock when used with a Mil-Spec buffer tube. The anti-rattle set screw should only be snugged up to remove the free-play, over tightening will damage the buttstock.

The differences between an A2 Rifle Buffer Tube and a Carbine Buffer Tube.
All MBA Buttstocks are Sling Swivel Ready.
This means that the buttstocks have molded pockets that accept Grovtec Sling Swivel Cups for use with Quick Detach swivels. The Sling Swivels and cups are NOT included with the buttstocks and must be ordered separately. This is to keep the cost of the MBA buttstocks down. Not every customer needs sling swivels and including them would raise the price of the buttstocks. The sling swivels are available separately. See the videos below for installation instructions using the install kit, or using a 1/4″ Allen wrench.
