One More time, If you bend the bbl the impact is going to move in the direction you bend the muzzle. If you want to raise the impact bend it up, if you want to lower the impact bend it down.
When woirking with sights you move a rear sight in the direction you want to move the impact, but you move the front sight opposite. "BUT" in bending a bbl we are not working so much with the sight line but changing the exit Direction from the bore. It will thus change the direction of the projectile in the direction you move the muzzle.
Simply visulize the bbl is shapped like Granny's rocker. Put the two ends level & it should be quite obvious to any one both Ends are pointing "UP". If the line of sight were thus level the projectile would be launched upward at a substantial angle dependent upon the bend. Of course nowhere near that much is needed here, just a gentle bend Upward to raise the impact.
