I have an older flat back 110 that is chambered in .308. It a true long action screw spacing but the "action" is only milled for the short action rounds. I would like to put a bottom metal in it to utilize 5/10 round mags. I have heard that there was CDI precision that made some for that setup but I can't find much information about it since they closed. Does anybody know of any others that may have any leads to a set up like this. Thanks.
