I am currently in the process of rebuilding my Crosman Mark I in .22 caliber. I ordered an O-ring set off eBay and it just came in a couple days ago. Now to clean and put back together. I will reach out if I have any questions.

Crosman Mark I .22

Ok, this was quick - someone else's thread got me thinking. On this Mark I, should I coat the O-rings in anything? And also, there is a brass piston, should I coat it with any lubricant? Anything else that I should do while putting it back together? Or maybe as important - anything I shouldn't do?

I always lube o-rings with silicone grease to enable them to slide in easily with less chance of damaging them.
A thin coat of the same silicone grease will prevent oxidation on the surface of other metal parts.
This is an odd category to post your question in, I think it would be seen by more people if it were posted in the General section.

Ya, I belong to a couple of other gun forums and there seem to have a gunsmith or maintenance section for these type of questions.

Got it put back together and it is working marvelous - pretty darn accurate at 15-yrds freehand too.
