I had a RPR, with a bunch of mods, and 2 spare custom barrels up on another site for a while. I think it is just that the RPR isn't selling well. There seem to be a fair number available used, and new prices if you watch sales can be crazy low. I wish you luck. I ended up deciding to keep mine and shoot it some. It has some benefits, and I used it almost exclusively for a season. I just don't like it as much as my "nicer" and more traditional rifles.
