I have 2 Predator actions. I’ve owned both from new. One is 11 years old and the other is 6 years old.

Both are on their 3rd barrel. Great actions and nothing to report apart from them being great actions. The smiths I’ve used haven’t had to make any adjustments to them (one of the main reasons for using a custom action in the first place). Nothing else to report. I know several of my shooting friends that also have them and nothing to report from them other than great actions.
