Aha, I see i have some competition... Did you also adapt this from the existing RBG turret on the site? I have a 2 barrel version in the works :D Yours is a lot cleaner design though...
When i saw the lego turrets on youtube i found out the mechanism, and also I have built knex_pls's Knex rubber band gun turret, then I made this one cause it is more portable and more non-wobly.
