Not sure I understand. Will a Defiance action drop on the Bergara stock? Probably but I wouldn't be surprised if you have to cut a relieve for the bolt handle and ejection ports (they are bigger in the Defiance Deviant actions). Otherwise, quality wise, you cannot even begin to compare a Defiance w a Bergara (even the premium action). Defiance is in a whole different level.
If you're going custom I think Defiance is excellent. I have 4 of them, but instead of a Bergara stock I would look at a Manners mini chassis stock (if looking traditional stock feeling). Again different price point but absolutely outstanding product (and a good bunch of guys in that company)
