Just for future reference, Olympic Arms selectors are ambidextrous and can be reversed to accommodate left handed shooters.
And I'm certain are far less than $40. Sorry I was too late to the topic to have helped in time.
Sounds like it may be possible that you are right handed but left eye dominant?
If you point your finger straight ahead like you're aiming a pistol at a distant target and close one eye at a time, and then you can see which eye you are using when looking at the target. One finger will be looking beside your finger and the target, while the dominant eye will be looking down the sights (over your finger).
Whichever eye is looking at the target when the other is closed will be your dominant eye.
Just for the record, my oldest son is this way.
