This receiver blank drilling fixture is made specifically for the Polish 7.62x39 and 5.45x39 receiver blanks. Helps drill out the hammer pin, trigger pin, selector lever, center support and trigger guard holes. Includes a 5/32", 7/32", 5mm, 7mm and 10mm drill bit. The stop pin for the rear of the trigger opening is the key to getting the receiver aligned in the fixture. Heat treated to last through the drilling of several blanks. MADE IN THE USA
NOTE: Will NOT work on a Polish Tantal since the selector hole is in a different spot.
