That certainly appears to be a M/70 bolt, I don't understand how it works with the M/54's bolt stop as it is quite a bit different than the M/70's. I would like to see a pic of how the M/54's stamped trigger guard/floorplate fits the inletting of the M/70 stock. The rifle is a unique combination of modifications to allow the use of a scope on a rifle that was never designed for scope use.
