MBA Buttstocks

The MBA Buttstock Family is the original Modular Buttstock Assembly designed for the AR-15 platform. The MBA allows you to setup your butt stock in the best possible configuration for you. The MBA-1 and MBA-2 are fixed “rifle” butt stocks while the MBA-3, MBA-4 and MBA-5 are adjustable “carbine” butt stocks.

MBA-1 FAQ

The “A2” buffer tube is the standard AR buffer tube. Originally, the M16 was designed for use as an infantry rifle with a “fixed” butt stock. The MBA-1 and MBA-2 are direct replacements for the standard fixed stock.

As needs evolved, the ability to collapse the butt stock to operate in tighter spaces found in urban areas or getting in and out of vehicles resulted in the adjustable “carbine” design.

All of the MBA Buttstocks come with molded pockets that will accept self-threading QD Cups, we sell Grovtec QD Cups and Sling Swivels separately. There are several reasons why they are not included.

  1. Cost, if we included the QD cups and/or QD swivels we would have to raise the price of the butt stocks $15 – $25.

  3. We don’t know which side the customer prefers to attach their sling swivel.
  4. The customer might want the QD cups installed on both sides.
