JL Billet Modular Billet AR-15 Stock (MBS™) Black

JL Billet's MBS™ (Modular Billet Stock) is a patented all aluminum modular buttstock designed to fit AR15 & AR10 Mil-Spec collapsible buffer tubes.

We start with chunks of 6061 T6 aircraft grade aluminum and precision CNC machine each piece to ensure an exact fit and perfect function. The MBS™ is a modular design that allows all components of the stock to be replaced if damaged, you can also change up the color and design to set your AR15 apart from the rest. We don't use any plastic on this stock other than the rubber base and cheek pads, this allows you to Ceracoat or anodize whatever color you like to accessorize and customize to your specific needs.

The MBS™ is skeletonized to reduce weight while maintaining strength and giving a look like nothing else on the market. Weight without a buffer tube installed is only 16 oz. It's not for the weak guys who can't handle a few extra oz in their rifle.

US Patent #8,984,791 B1
