During a trip to gun shop saw garand that had rust on the op rod near the piston and also heard gun guy state the oprod could be bent.

Always looking to learn more about weapons especially great rifles like the garand, How do you inspect the oprod? Was there corrosive ammo made for the garand that could have caused the rust? What does a bent oprod look like?

Anyone with a garand or two who can answer these questions, I appreciate it!

As long as the piston is OK, it doesn't really matter if the op-rod has rust on it. Just remove it. There was corrosive ammo issued and it may have caused the rust, or just general lack of care from any of the previous owners over the last 60 years.

That said, it is SUPPOSED to be bent. There is a gage that could be used to check if the bend in it is within spec, but do not try and straighten it.
