No D/T necessary - If you check the rifle's left receiver wall, high and near the rear, you should see two small screw heads about 1/2" horizontally apart. They are headless plud screws, that temporarily fill/plug the factory prep D/T'd holes for a reveiver peep sight sttachment.
Winchester's been prepping the Model 94 for a lotta years, and has only stopped in 1983 with the 94AE angle-eject models, which can take a peep sight in the rear scope mount prep holes.
