Nerf = Fun. Yep, that's about it.
Very interested in how your going to get the turret to barrel seal. I look forward to seeing more of this!
The current plan is to put an o-ring around each barrel - I replaced the stock tank with one from an original Panther. Coincidentally, I had to remove enough excess plastic off the barrel end of the tank that I ended up with only the flat tank wall - so it's at least going to be a smooth surface :)
