don't mess with it yourself, first send it back to Ruger and tell them to fix it.
I'm sorry, but some funny sheet right there! Have Ruger fix it. Good one!
Why do you think its funny?
Ruger May, I said "may" be able and willing to repair the rear site, but they will NOT repair, straighten, properly align and torque the gas block and screws. A properly adjusted gas block is a must for any kind of acceptable accuracy out of a Mini. As a mater of fact the gas block screws used to be staked so they could NOT be adjusted correctly.
