Due to the low cost of Wheeler action wrenches, I simply carved out a place in the wrench for the picatinny rail to fit. So I don't need to remove it to swap barrels. I also do things a little different... I don't need to use a barrel vise, except for that first removal of a shouldered barrel from a receiver. Otherwise, I clamp the handle of the action wrench into the vise with the barrel pointing straight up. (Pardon the Remington 700 in the picture... it's a Remage conversion that goes together the same way a Savage does.)
