Had my AK apart for cleaning and when I put the selector lever back on I couldn't get it to go forward, forgot to pull the trigger while doing this and instead took a screw drive and tried to push the hammer to the side a bit so the selector lever would clear it.

Put a bit of force on the receiver from the angle I was using the screwdriver and noticed the right side of the AK receiver flexing as I was doing this, ie I could see the sheet metal actually move outward and flex back inward a little bit (under quarter inch)

Could I have damaged the receiver??? Would this cause the receiver to fail or anything like that?

I can't take it to the range at the moment but I put a mag in it and cycled to see if it chambered and ejects and it does.

Anything to worry about???
