I know this is a super narrow post in the help ii might provide. This has to do with specifically the wildcat vp bt. Changed mine to a CF bottle today and at first couldn’t figure out why it was hitting the stock before I could get it screwed in all the way. In my defense I had an extra fx valve and never really looked at the one in the aluminum bottle. I should have taken pics I apologize. If you plan to do this you will have to remove the valve from your aluminum bottle even if you have an extra. This is because there will be a spacer on that valve needed to space the bottle out from the stock. Took me a few minutes to notice this. Hope it will help someone.
