You may have more luck if you post in the classified section.
I buy donor actions from places like Walmart or Dick's sporting goods. They usually have them on sale a cheaper than normal gunshops. Then you can sell the barrel and stock and get a couple of bucks back. Dick's had sale this past summer on Rem700 Sps varmint at around $550
I'm looking for just the bolt, the action came to me boltless and thought someone may have one before I order one from PTG. I mag give the other forum a try as well.
