I have never purchased from either of these companies myself, but haven't hard bad things about them either. Samco has barreled receivers (who needs a stock if you're going to spoterize it?)

http://www.simpsonltd.com/index.php?cPa ... 4a6027c80eI check the "Mauser" and "Husqvarna" sections one a week. If you call them they will pull the rifle and go over it with you on the phone—very helpful sales people. I've bought from them before and was very please. I would get a gun with a “very good" bore however, as their "good" bores are strong, but the groves are quite dark.
Hope that helps
