LUTH-AR Introduces Two New AR-15/AR-10 Carbine Stocks

Posted on October 8th, 2015 by ar15news

After using the LUTH-AR MBA-1 on one of my favorite precision AR-15s and absolutely loving it, I was really excited to hear they were introducing two new models of the MBA (Modular Buttstock Assembly). The original MBA-1 and MBA-2 stocks mounted to an A1/A2 buffer tube. The new MBA-3 and MBA-4 are Carbine stocks meaning that they will mount directly to your standard AR-15 buffer tube for collapsible stocks. 

The MBA-3 Carbine Stock is fully decked out with an adjustable height cheek rest, 3-axis adjustable buttplate, 1913 picatinny rail section on the bottom of the stock and more. 


The MBA-4 Carbine Stock is more of a stripped down version of the MBA-3 letting you add the accessories you want. It does use the same frame as the MBA-3 including the 1913 rail section on the bottom. 


– Fits .223 & .308 AR platform

– Easy to replace & quick to install
– Strong fiberglass-filled nylon
– Features a picatinny rail 
– Adjusts to 15.75″ length-of-pull
– New 3-axis adjustable buttplate
– Revolutionary anti-rattle set screw
– Available in black, FDE & pink.
– MBA-3 weighs 18 oz.
– MBA-4 weighs 11 oz.

Both of these stocks look really great. Whether you are looking for a more basic setup or the fully loaded, these are sure to fill the need. All LUTH-AR MBA stocks are available for purchase now at
