RE: disassembling an optima
That is a real shame you have to send the rifle in...
I would think if a part gets rusty, fowled or dirty, there must be a way to keep it clean. On my triggers, I spray them with brake cleaner (after I remove them from the barrel/stock of course), then pour some alcohol over them, and finally hit them with a air compressor until they are dry. It seems to work. Then a shot of oil. So far no more crud build up, and I never saw rust yet. I see no reason why that would not work in the assembly you have unless of course it does not come out of the stock.
If I had to have a rifle I could not break down completely, and clean all the parts myself.. it would be on the auction site real fast. Whether it was a CVA, a Thompson Center Arms, or what. In fact I traded off a Jukar pistol for that very reason.That and I got a heck of a trade for it. Maybe that's why I like the older technology rifles.. less moving parts, all parts can be cleaned, and put back together..
