Hi guys, haven't posted in a while do to being in school, but a few buddies and I are all looking to build similar rifles. What we are wanting is an AICS magazine fed, Savage actioned 6.5 SAUM. Since being in school it appears there are lots of variations available for Savage actions, as well as the Axis line, etc. Should I be looking for a specific type of action? If we use a bottom metal meant for AICS mags, will a short action be ok?
