Working on a M40A1 clone. Somebody mentioned that the armorers in Quantico would tack weld the BDL magazine box directly to the action. Is this true? If so, what locations around the box did they weld them? My action has the screw hole for the ADL retention screw, but I cannot find a BDL box with the tab on it to screw it on.
