This is my ics g33. Gearbox is the ics v3 and is well shimmed. I run this with a 6.05 barrel and src hop up chamber and ics stock bucking/nub. Gearbox gets 19 rps with 9.6v battery and is really nice for a g36c. Range is great for the 248mm barrel and is most effective at medium engagement ranges. My sweet spot with burst is 125-150 ft. Max range is 175ft. This is my kit and am really liking it so far. Its a g36 so its not the most popular gun and the futuristic furniture isn't really found everywhere. I like it because its uncommon but to its advantage.
