I have the CTR. I went to their website looking for a “Tactical“ model. Other than the Tac A1 and the CTR which is “compact tactical rifle”, I can’t find anything. If they have a new rifle that’s called just the “Tactical” that doesn’t appear on their website, then it’s possible this is incorrect information. Love when manufacturers do that to us. I’ll concede it is highly possible that such a model exists that I’m not aware of, so perhaps the information I provided is in fact incorrect. In which case you’re no further ahead.
EDIT: I did see in the Tikka Old Models section of their website is a gun they call the T3 TAC. But this is pre-T3X, and so shouldn't be what the OP was asking about.(T3X Tactical) So, is there a T3X Tactical they don't list on their site? If so, why?
