I was given a non working 180 a couple years ago. I put a new valve in it and it shoots great. I would like to refinish the stock. Any suggestions? It's in good shape. No gouges or anything, it just needs a refinish. What should I use?

IIRC correctly, they came with some sort of varnish finish. Personally, I would strip that shit off with a citrus based paint stripper and then go with a hand-rubbed oil finish -- either Birchwood Casey Tru-Oil or simple boiled linseed oil.

I've always liked the 180. It's the little brother to the classic 160, but one powerlet only. They're simple to convert to bulk-fill, btw. I've got one sitting around that I need to reseal.

Mine is the older cross bolt safety one. I'm not sure what the finish is on it now. It just looks like wood, not shiny at all. I've been looking at some custom bullpup conversions that look neat but I'm not sure if I could get the trigger mechanism right.
