I have recently acquired an Anschutz 1532 and went to adjust the tension on the action bedding screws. The trigger guard seems to be a separate piece from the bottom metal and one of the action bedding screws at the rear is underneath the trigger guard in such a way that it can't be adjusted without removing the trigger guard. The front of the trigger guard seems somehow locked into the bottom metal but I can't figure out how to put pressure or which way to put or pull pressure to get it loose from the bottom metal and I don't want to damage or break it....Any ideas please????
