gingersnapples me and mc hammer time were both refering to the BT TM-7 paintball marker, not the nerf gun, but I do agree the nerf gun could be made into a nice shotgun,
if you did that magazine with the tube, (i forget exactly) but its kinda like a shotgun mag for the air powered ones.
That way it could fire, and the mag would be on the side, in the correct place.
