This is a jig designed for drilling the rear trunnion holes on an AK74 receiver bent blank. The holes are threaded to use the stock screws that should have been included in your parts kit. Place your rear trunnion on the jig and screw it down. After it is secured, you can clamp the lower jig portion in a vise with the trunnion holes normal to the drill bit in your drill press. Align the jig so the trunnion holes are inline with your drill bit, secure your drill vise and drill press table and slide the receiver over the trunnion and clamp it with a C-clamp or something similar. Drill through your receiver so you can then rivet the trunnion to it.
