Are you looking for a stripped action (receiver, bolt, and bolt stop) only or do you want a complete ADL or BDL setup?
I have several used R/H blued long actions (no J-locks) in matte or gloss with the standard bolt face. I typically get $285, plus shipping/insurance for the stripped actions. I have all the parts for complete actions and the price depends on what you need. I think I also have a magnum bolt face R/H long action but would have to check for sure.
Let me know if you're interested.
