Who else owns a J2 and a S5 or S6 - do they have the same valve, valve stem, hammer, VRA, IVG and the like?
If so - then yes - but NONE of the pneumatics are mentioned - although I know that CCM has them.
The J2, J2L, S5, and S6 have the same lower tube kit - valve stem, hammer, IV, etc. CCM moved from the blue aluminum valve body to the hardened brass body in their recent runs.
