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!
