Hello AGN:
I sold some of these FX Impact o-ring reseal kits awhile back and they were pretty popular but they didn't include the M3 so I just spent way more time than I care to admit very carefully reviewing the following FX schematics to update the kits to include every o-ring you'll ever likely need to service your beloved Impact:
Each one of these kits will now allow you to fully reseal every o-ring in the action, power plenum, factory regulator(s), barrels and, yes, even the air bottle at least once (with some o-rings to spare) FOR EVERY FX IMPACT MODEL FROM THE MKI (after serial #183534), IMPACT X, MKII (with or without Power Plenum) AND M3 IN 0.22, 0.25 AND 0.30 CALIBERS!!! Please note that most other o-ring kits are model/caliber specific or are only for a specific part of the rifle (action, regulator or barrel) - whereas my kit will include all the o-rings you'll need to reseal the entire rifle (except for some of the older shrouds - but those don't really ever need to be replaced). Here's what's included in each kit (o-rings will be separated by sizes into ziploc bags and properly labeled):
