AK-BUILDER Receiver Blank Drilling Fixture
This tool is made specifically for the Polish 7.62 x 39 and 5.45 x 39 1mm receiver blanks that were just imported. This will not work for a Polish Tantal since the selector hole is in a different spot. The fixture is machined and heat treated to last through the drilling of several blanks.
Drills Hammer Pin, Trigger Pin, Selector Lever, Center Support & Trigger Guard Holes
Drill Bits Included: 5/32", 7/32", 5mm, 7mm, 10mm
Look at the pictures above and the description of each shows how to use it. The stop pin for the rear of the trigger opening is the key to getting it aligned in the fixture. After that it's just as simple as putting in the receiver support and setting the fixture on the aluminum plate on your drill press.
