I have tried many solutions, but the crossover stock is the ultimate solution. My left eye dot is permanently installed when I shoot a straight gun and a right eye dot is permanently installed on the glasses I use with the crossover gun to reinforce my use of the left eye when using that gun. Remember, as one poster emphasized, the dot should only block the front sight and the front end of the rib, leaving the view of the target unobscured. Some coaches just don't understand the proper use of the dot. The dot is not meant to make you a one eye shooter. The dot is meant to make you a two eye shooter who does not look at the gun with the off eye. The placement of the dot is a careful procedure when done correctly.
