I made this one a while back as a prototype but decided after making it the design needs work. It is too heavy to carry around I leave it on a roll around cart which works fine for me because I don;t travel from home to shoot at least not yet. I make things for the boating crowd from this marine plastic. I may make another version that holds a couple guns but does not incorporate the tank. Or if I do make one for a tank it will be made with a dolly like the old folks use with their oxy tanks.
