Take it apart and clean and moly lube. Deburr internals and replace the piston and breech seals. I think the MP 512 is based on your rifle and the seals would be the same. 15 years is a long time for her to be sitting but she may surprise you and be in relatively good shape. Any rust on the barrel etc? Let me know and I can try to get you info should a new spring be in order. Enjoy tuning her up....
I fired three shots just to see if she would hold air and everything seemed fine. My dad helped me cut 1.5" off the buttstock so my 10-year old son could use it, but other than that it looks like new. Even the trigger was as smooth and crisp as I remembered it. I just don't want to get carried away without some maintenance.
I found the manual and it has the usual exploded parts drawing so I could take it apart to replace seals and lube it but I don't have the tools to deburr parts, unless there's a wheel or something for my Dremel. I also don't know what lube to buy, so please keep the advice coming. I'll take some pictures when Canada Post delivers it.
