I ordered a Millett TRS-1 from US Armorment. It had a problem where the windage knob had a cant to it due to a crooked screw. Called the guy, he said it was a warranty issue and to call bushnell. Called bushnell, they said to return it back to the place where I purchased it. Called USArmorment again, he called (so he said but I suspect that he didn't because he got through right away where as i had to wait on hold for a while) bushnell while I was on hold and said for me to call bushnell right away they were going to take care of it. Called bushnell and talked to Jacob after arguing with them for 30 minutes he sent me a new one very quickly. Now when I mount this scope on my rifle and bore sight it I have to unscrew the elevation knob all the way to the top to get it on the paper. So, I change to a one piece base, lap the scope rings, still the same. I mount another scope and it works fine. I'm at my wits end here. Is there something obvious that I am missing? Burris XTR rings, Savage Mod 10, Burris two piece or EWG one piece picatinny rail.
