There is no store. BrickArms is based in WA Redmond, they ship, but they rarely sell in person, except in conventions by Will, Badger, or a re-seller.

BrickArms was created in 2006.
why did brickarms stop selling to the public
LEGO and brickarms are not connected, but brickarms makes their own LEGO guns that are compatible with LEGO especially the minifigures.
There is no set date. Brickarms does not have a festival, but attends and sponsor conventions. You have to check the date of those conventions, not Brickarms.
