[QUOTE="DMCI, post: 17567, member: 1730"] Friday, I had a problem with my SN-3 on a AR-10T. I mounted the scope and found that I was totally out of Windage and elevation. The scope was as far down as it would go and all the way to the left and still wouldn't center on the bore sighter. I took it to the range to test it even further and it wasn't on the paper at all and this at 50 yards. I rechecked it with the bore sighter and still it wouldn't center. So I took the bolt out of the rifle and bore sighted it at 100 yards by looking down the bore and moving the scope until I got the same picture in the scope as I had in the bore. Then I put the rifle back together and surprise I was on the paper, but a foot low and 8 inches left. I cranked the scope up about 12 moa up and 15 moa right and was in the black. I then moved the rifle to the 100 yard line and made the final corrections for 100 and everything is fine. The bore sighter, a magnetic one is in the trash. If I hadn't worked through the problem, I would have sent the scope back and later gotten a note saying that there was nothing wrong with the scope. Virtually every problem I had with a new USO scope could be traced to some form of mounting problem. I mentioned the difficulty getting the AR10 to take the Roll OFF mount to the Factory on the phone before I took it to the range and they said the gun manufacturer sometimes has problems with their rail straightness. This of course, was not the problem either. [img]images/icons/grin.gif[/img] The knowledge about mounting problems of one form or another being the cause of most problems with these scopes has saved me a ton in postage. Other than Mushy clicks on one ST-10, I have never had problems with a USO scope. Had I been expecting difficulties I would have been one of those getting my scope back with a letter saying there was nothing wrong with it. Another problem I had with the failure of a scope had to do with it not fitting on the rail. What I didn't realize at the time was that the scope was too far forward and the big power changing knob was hitting the rail. It was funny because at that very minute there was a guy that wanted to look through the scope and at the same time I was fighting the mounting problem. Unfortunately I must have seemed rude to him, but I just couldn't get the thing to set on the rifle properly. The after looking at the thing for a few minutes in a less stressful mode, I saw what the problem was, moved the scopes back a little and everything was fine. The problem was that it wasn't missing by much, and the rings would actually lock up, but not seat totally. Frustrating, especially when this guy almost insisted in looking through the scope at that very time. I have a friend that is having a problem with a ST-10 EREK. He is having a problem getting it adjusted properly, but I think there is a possible problem with the instructions that came with the scope. That may have to be changed, or at least the verbal instructions he got are reversed from written instructions, we don't know yet. It these cases there doesn't seem to be anything wrong with the scopes, they all worked fine. This of course is not to say that every problem with these scopes is a mounting problem, just everyone that I have had. I can only speak from personal experience. I now have 8 USO scopes. DAN TEC's big problem with USO, however appears to be the result of some business relationship issues between a Salesman and his principal and nothing whatever to do with product quality. What a novel situation that is! [img]images/icons/grin.gif[/img] D. [img]images/icons/smile.gif[/img] [ 12-22-2003: Message edited by: DMCI ] [/QUOTE]
