Okay, cool. Kinda hard to find reference on the screenused screw. The photos of the resin cast stunt props are a bit murky.
I’ve only been hardcore-researching this prop for a few weeks, so I don’t know all the ins and outs of it.
I also gave the film a rewatch, the other night. A few observations:
* Slotted screw only, no Weaver knob in sight.
* I think a good number of shots—even some close-ups—actually feature the rubber stunts, despite some people using those shots as reference for hero prop details. For example, the close-up of the blaster hitting the ground when Deckard drops it during the final chase with Roy. Looks like a stunt, to me. Literally so, since the prop falls to the floor and bounces. The hero only seems to appear for live-fire moments and non-action close-ups (Deckard stalking along the rain-soaked wall during the final chase, Deckard slowly reaching down to remove the blanket from Rachael at the end, etc,).
*I didn’t notice the green LEDs illuminated at any point. Also, the (definitely cut) white wires coming from the sight seem only visible in that one close-up of Deckard stalking along the rain-soaked wall. The rest of the time, they appear either absent entirely, or covered with black tape. Either way, no lit LEDs the movie that I could see.
