Luth-AR MBA-4



If you'd like an entry-level option to the brand-new MBA-3 buttstock just released by LUTH-AR, consider the Luth-AR MBA-4 collapsible stock. This stock is extremely ergonomic and easy to install, making it the ideal replacement for your current carbine stock. The unique design of the stock gives it a “tacticool” 21st century appeal that will not be found lacking on your rifle.

If at any time you want to take advantage of the functionality of the MBA-3, no problem! The Luth-AR MBA-4 is completely modular and can very easily be upgraded to the same look and functionality as the more expensive MBA-3 with the addition of a cheek riser and a butt plate. Compared to other adjustable buttstocks on the market, the MBA family by LUTH-AR is by far the most adjustable AR rifle stock available. This collapsible stock is also extremely lightweight at 10 ounces.

The glass-filled nylon used in the construction of this Luth-AR MBA-4 carbine buttstock enables it to withstand the most rigorous tactical operations with ease. New features include a bottom picatinny rail, and a set screw for rattle elimination. The stock will fit securely on most existing commercial and Mil-Spec buffer tubes for AR-15 type rifles. The product will also fit most .308 AR-style rifles.

When purchasing parts for your AR rifle, it is important to ensure that you are investing in a product of the highest possible quality. Your rifle will only be as reliable as the parts and accessories used with it. Be sure you purchase the best.

  1. High Speed, Low Drag 4 Star Review

    Posted by on 11th Nov 2016

    This is my second attempt with marrying a minimalist buttstock to the AR I recently built, and I am happy to say that it was almost exactly what I wanted. There was a little bit of slop, but nothing more than to be expected. The rifle has an RRG Upper with a Diamondhead VRS free-float handguard and an Aero Precision Lower. The Luth-AR Skullaton Collapsible Carbine Stock finished the look I was trying to create by adding the final touch to make a sleek, aggressive-looking AR.
