Childers Guns - Trigger Guard Rivet Layout Guide (AKM, AKMS, AK-74)
This jig will allow you to use a 1/4" Transfer punch to center punch all the holes for the trigger guard rivets (bottom of a Polish blank).
It will work for a 47 or a 74 blank.
These are made of machinable plastic, they are not a drill guide. They are designed to be a layout guide.
Use a 1/4" Transfer punch, not a standard / tapered center punch.
