B&T MBT Stock with Haga Defense aluminum adapter for mounting to 1913 rails/endcaps.

Worry free mount fits rock solid without locking tabs allowing for infinite height adjustment so that you can get the stock looking just how you want it no matter what platform you're using.

This stock assembly is roughly 2.5/8" tall where it meets the back of the firearm. Using it on firearms with shorter backends may look silly so measure first! Some examples of firearms NOT to use this on: SIG MPX/MCX, Ruger PC Charger, B&T GHM9, etc. Measure first!

WARNING: When the stock is locked in the folded position, lift the stock upward on the hinge to unlock it before unfolding. Failure to do so can result in damage to the hinge. Haga Defense will not accept returns due to damaged hinges.

This is NOT a pistol brace. Attaching a stock to a pistol makes it an SBR and requires NFA approval. You are responsible for knowing and following your local/state/federal laws!


Curious about how B&T's "Coyote Tan" looks compared to your standard "FDE"? See the image below. The "Coyote Tan" MBT stock is shown next to parts colored in "Magpul FDE". As you can see the Coyote Tan is a little lighter than FDE and may not be a perfect match to other FDE components if that's what you're hoping for.
