You can make anything that shoots a cartridge based on the 223 case with what you have. Rem 700 bbls thread right in. Stocks are different, but not that tough to get (and you already have a couple). I've done a couple of these (still have a multi bbl, multi bolt version coming together) and they turn out pretty decent. Only downside is that the CFC circus doesn't want to reclassify them as rifles anymore (they did my first one, refused my second). As to worth, less then a 700, more then a Stevens. - dan
