Opening the chokes wouldn't hurt the value anywhere near as much as having Briley attempt to install thinwall mobile chokes. I've seen examples of Briley's attempt on thin barrel walls end up in complete failure and a ruined set of barrels. On the other hand, it would be easy and safe to just open up to .005 and .010 constriction.
