Piston was scored bad on the exhaust.Even had a little on the intake
Ring wasn't intact.
Honestly, knowing this saw & the fact you have scoring on the exhaust side (only? not sure) it does sounds like Gas: Either bad gas, bad mix or improperly adjusted carb (to compensate for difference in gas).
Have you opened up the saw to see if the cylinder is salvageable?
