Got the mag box cut off the bottom metal and shaped as intended. I thought I was going to have to weld some of the sling hole but when I filed the bow to the desired shape it dissapared so that is one thing to tick off the list and then it was simple matter to inlet it into the stock. I fitted the altered trigger from my 7x57 so I could comfirm it was all going to work untill I can get the two into one welded for this rifle. I still have to file the slot in the trigger bow base to allow the fingerpiece to travel to the rear further because of the change in its position.
