Update on this matter:
After almost a month GAT's finally got the sight back from Sightmark.
No work done on it. None. They shipped it back broken. They didn't even bother looking at it and simply did a return. Right now GATs is calling them about it to figure out what the deal is. GAT's would have swapped the sight with one of their but they ran out, after I suggested they do this in the first place so I can stop coming back there and not have to deal with this anymore, but no, Greg had to screw me over on that one. I was so fuming pissed when I left that the employee's started feeling bad that Greg screwed me over about this.
Oh, and if you need any gun smith work done, the head gunsmith quit for medical reasons. So if it's pretty in depth besides cleaning and sight work done, need to go somewhere else.
