Disappointed in BSA Bore Sight
Bought and tried out a BSA bore sight. It's the type holds a grid above the barrel and you sight in on the grid. Well, the shaft that you mount the grid device on was so poorly designed that the grid device swings around to underneath the gun. Plus, when the grid is up top, it's really high and only a scope mounted on tall rings gets anywhere close to the grid. Took it back and bought one of the type the sticks to the end of the barrel with a strong magnet. Worked much better.
Live well, be safe
