Hello, I have been browsing the forum for some time now. I am going to build a 6.5x55 for long range. I have 2 of the M96 swedes and I know the modern pressures aren't good for these awesome mil rifles. I found a 110 in 3006 used. The guy said it is a closed bottom (hidden magazine) and the first part of the SN is F0983xx. Am I correct in assuming this is pre accu trigger and accustock? Also, can I put different bottom metal on this when I build to have an external mag. Thanks in advance, I am looking forward to building this thing!! --Cole
