Along with the firing pin I want to order eventually, I want a stainless gas valve, as I heard a lot of the Yugo SKSs have corroded valves from the get go. I haven't taken mine apart yet, but I would at least like a spare if mine should ever go bad, but the stainless is more resistant to corrosion correct? I use the modern commercial non corrosive, but I do have a case of Yugo surplus that is my back up supply. My questions are;
1. Normally the firing pin should be free, as lube could gather residue and gunk. With the Murrays firing pin since it is spring loaded, do you recommend any lube?
2. Should there be any anti-corrosion application to the new gas valve?
