Thanks! Your only 250 miles east of me, practically neighbors. For now my plastic tanks work great for what I do with them. I put all the metal on the Tiger I just because I couldn't resist having at least one with some metal on it. I do want to replace the gear box because from what I've read it will fail at some point from the extra load, which is the best currently? I have been thinking of replacing the main gun on a couple of them but after lots of searching I can't seem to find anything but stock replacements. I may have to go the modify it route. I ran the Abrams gun through my chronograph and through 5 shots it was from 99 to 101fps, pretty slow. Is there a good replacement gun or is modifying the stock gun the only option?
