BUT... the round detent part that should drop/ride/drop/ride/drop/ride on the threads, is simply not there. I even pushed on the back of the spring to try to push the detent through to the inside but nothing is clearing the threads of the GB. It's very hard to pus that spring. In fact, and I know this is not actually possible, but imagine if the spring were made to spring the other way and always hold the detnet up instead of push it towards the screw. That's sort of what it feels like. Which I know can't be the case. Like I said, I operated this thing before I ever installed it. I know what the clicks feel like. I can see the parts. I get what's supposed to be happening now, but that detent is simply not pressing through the side wall of the GB and I can't even force it. Which seems really bizarre for just those three parts. There is no damage on the screw, it looks perfectly fine. Still nice and black, no rough threads, no gouging, no nothing.
I can look up inside the GB and see the tip of the detent. It's just above the inner surface where the threads are cut in. It -seems like- I should just be able to take a screw drive blade and tap it lightly from outside and it would just pop right into place. But it doesn't seem to want to do that. It's like it rode up on the screw threads once and got stuck inside the GB wall.
ETA: Ok, man, this is really crazy. I just wedged a screw driver on top of the spring. flat to flat. put a t-handle ball driver in the adjustment screw. Turn the screw and the screw driver will bounce up and down as it detents. Remove the screw driver and nothing. you can turn the screw by hand, no detenting. It's like its sprung backwards. Is that even possible?
Could the front of the detent be sheared off? Again, no sign of anything like that happening by condition of screw.
