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 Cerakote or anodize whatever color you like to accessorize and customize to your specific needs. RAW STOCKS WILL SHIP UN-ASSEMBLED UNLESS REQUESTED OTHERWISE.
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.
**For those of you in California, the MBS can be used as fixed stock as well with the use of a longer trigger set screw**

Love It!!
The pictures of the raw one does not do it justice, this thing is beautiful, it has some weight to it but not too much. It fit my buffer tube pefectly and feels good against your shoulder. I wanted something different and this far exceeded my expectations. It is a quality made piece and well worth the extra money.

Not of this world
This unit is such a work of art I almost didn't want to use it...almost. It's a robust piece that adds a little bit of weight to the rifle and reduces felt recoil. Perfect fit to my buffer tube with no slop. Comes with the limiter for the adjuster trigger to prevent accidental removal. I'm extremely happy.

Modular Billet Stock
This stock is excellent! Only complaint is the Burnt Bronze stock is much darker than my burnt bronze lower receiver.

Top quality
This stock was the cornerstone for my build. I do not think the pictures does this stock any credit it is a work of art. With the glass smasher and the pistol grip from JL has a unique quality from all the other AR's out there. I would recommend it for anyone that wants a robust stock and not some cheaply made polymer.

Work of art
I ordered this buttstock in raw and let me tell you it is gorgeous. The functionality is perfect, I love it. The only bad part is it doesn't come with the buffer tube or lock nut for the price.

Pretty and Precise
I was hoping to find a straightforward stock with a minimalist aesthetic yet still possess some cutting edge charm. This is that. Well done.
