I want to pick up a rebuild kit for my Smartmag (post magic box) for the day it finally fails. 6-7 years under my ownership and the only thing I have done to it mechanically aside from disassembly and oiling is installing a Level 10 kit about a year ago. I have not replaced any orings not associated with the Level 10 and still no leaks. Now to the question, does a standard Classic mag rebuild kit... Attachment 35135
contain all the necessary orings for a classic valve and
a level 10?, or will I need additional orings for the level 10?
