I've bent barrels. Pretty simple, but probably not for the faint of heart. Any hydraulic arbor press makes a fine barrel bender. A pile of soft 2x4's and 4x4's and some 1/4" rubber sheet for the thin barrels, will keep you from putting a flat in your barrels. Randy's problem could be fixed in a few minutes this way. ...or countless hrs of messing with the stock.

Bending the stock up would raise it as well. It probably would take an 1/8th inch to make a noticeable change in POI.
