The AK-BUILDER milled receivers have a 1/4" hole center of where the trigger hole is cut out on the bottom of the receiver. This hole lines up with the 1/4" hole of the drilling jig. Use the 1/4"-20 bolt and nut through these holes to hold the receiver in place. After that it's just as simple as using the correct drill that fits each hole. When drilling on it's side, use the aluminum plate to level the drilling jig on your drill press. If your receiver does not have the 1/4" hole you can align the receiver using the trigger guard rivet holes, clamp into place, use the drilling jig to drill a 1/4" hole into the bottom of the receiver, then proceed as mentioned above starting with the 1/4"-20 bolt and nut.
