Impact barrel sleeve oring

.22 liner internals and assembly video 😎

Correction on the liner OD orings they are 4.42X2.62mm I recommend 3 oring or more.

Note: .25 .30 cal there is no internal oring on the jam sleeve— wall thickness doesn’t support oring groove.

Hi, Impact newby here. I new gun and had to install a CF sleeve on my M3 ofcourse :(. So long story short that adapter O-ring came out with the 3 barrel o-rings. To fix it from what I read here I'm looking at taking the barrel apart or do I leave it as is (no sure what that oring does).
What is needed to get the barrel and the stainless piece apart? What kind of glue is in there? would a heatgun be enough or is a torch needed?
any help is welcome here. Thanks in advance.
