Air Venturi Has anyone put new prints in an air venture avenge-X?

Here is a YouTube link that will give you a good step by step to follow when doing a reseal to your Avenge-X. The video is not in English but you can just turn off the volume and pay attention to the process:

The only O-ring kit for the Avenge-X that I know of is from PyramidAir ( https://www.pyramydair.com/search-results-ext?keyword=avenge-x seal kit ) and here is their schematic page for the X : https://www.pyramydair.com/model-schematic/m/air-venturi-avenge-x-classic-synthetic-stock/5773

I just did a reseal to my X following the video above. It went without any issues except the O-rings I was replacing had failed by becoming hard and frozen in place. I suggest you go as far as you are comfortable to replace the original seals and then maybe shop for aftermarket O-rings from Internet vendors because the factory O-rings are not all that.
 
I've posted previously about the o-rings in the Avenge-X
I was quite frustrated with mine at first and had leaks at several locations

Some of the factory o-rings were almost square and hard enough they shattered when removed.

After braving a complete tear down and replacing all the o-rings, I learned a LOT about the gun and where things go.

The only repetitive replacement has been the two o-rings in the regulator (one inside and one on the tip)
These are fortunately easy to access and relatively east to replace.

The only other significant learning was that using thin silicone oil on the regulator o-rings has been lasting a lot longer then when I tried silicone grease.

When the seals are all in good shape, my gun holds 4,300 PSI for weeks on the rack but I struggled to hold air overnight at times.
