[12.06.2020 Update: NEW & IMPROVED - I've updated these kits to include the C3 bumper as well as the x-barrel liner lock and outsider liner o-rings for the 0.22, 0.25 and 0.30 x-barrels...newly added o-ring sizes are listed in italics below.]
Hey AGN:
I recently had to get some A27 x-rings to fix a leak under the air gauge on my 0.25 caliber Impact MkII so ended up ordering all the relevant o-rings I could find from http://www.oringsandmore.com using this thread:
https://www.airgunnation.com/topic/impact-o-ring-list-corrected-with-links/
The minimum orders for each size is way more than I'll ever need (hopefully) so I have a ton of extras for other Impact owners and can hopefully save them the time and effort. I don't think this is a comprehensive set but it should cover most of the common o-rings that you'll need to replace over time. Based on the above thread, these should fit the original Impact, Impact X and also the MkII – but please review sizes listed below and do your own research to make sure you're getting the specific sizes you're looking for (some o-rings are for specific calibers, production dates, etc).
Here's what's included in each kit (o-rings will be separated into ziploc bags and properly labeled):
