I recently got a KP II and love having tons of spare parts around for repairs (I have 15-20 rebuild kits for my DM9 along with 3-4 extra detents and 2-3 eye pipes, solenoid gaskets, etc etc) So I am itching to get parts for my KP II. What spare parts are most needed? (ie cup seals) and what other parts should I invest in for possible trouble down the road? (ie, replacement valve)
Iv been looking around ANSgear and there are a lot of extra parts, but which ones would serve me the best?

Im looking at the rebuild kit x3 (or x5) and the Overhaul kit. What other things should I add to my list? Any input or ideas would be much appreciated.

I would say the X5 Overhaul and complete oring kit. They tend to eat the one inside the reg and cup seal. Detents with the whole kit.
