You guys are nuts to even consider bending the barrels. For under $250 any competent stock bender can bend the stock up to correct the low shooting. Before you send it to a bender, use a consistent aim and shoot at a single point for many shots until a definite hole develops where the pattern centers. You can then determine how much the stock needs to be bent. If you shoot at 20 yards the pattern will develop quicker and will be more visible. Then use the ratios of the shooting distance (720 inches for 20 yards) and the adjustment needed, say 6 inches, to the disance from the front sight to your eye, about 36 inches for me, and solve for the adjustment of the stock at the point directly below your eye. For a gun that shoots 6 inches low at 20 yards, the correction would require you to raise the stock (6X36)/720 = .3 inches directly below your eye. That's probably easily achievable with an RBL. Remember that the adjustment is made at the point below the eye rather than the heel of the stock.
