Hey everyone. Looking to see if anyone can impart some of their experience regarding what I hope to be a small problem.

I just picked up a century Yugo and for the most part it looks to be in good condition. Finish is good, rivets look solid, cheek weld uncomfortable as ever. The only issue I saw is on the gas piston.

There's a fair amount of pitting / general badness going on and I won't be able to take her to the range for another week or two. I'm curious if this is going to affect it's ability to cycle or if it's just cosmetic.

Additionally, since the integrity of the piston has now been compromised, what steps should I take to prevent this issue from getting worse (is that even possible at this point)? Would it be worth it to simply replace the part?
