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.

You must select weather you want the 1mm drilling fixture or the 1.5mm drilling fixture.
