The email issued mentioned earlier this week is now fixed! You may also have received previous emails that were meant to be sent over the last few days - apologies, this was a one time issue and shouldn't happen again!
Edit: Actually, that chart is clear as mud. Your 452 should be a 452 European (vs. 452 American). As such, it will have a 11mm dovetail. The Talley rings you linked are for the 11mm dovetail. So still yes.
when you get it scoped I would like to hear how you like the 12 groove barrel,,,some claim they shoot better and others say they cant tell any difference..
