I just purchased LMT Tactical Rear Sight for my Noveske N4 Low Profile. The rear sight fits, but when I attempt to adjust the windage the long and short range aperatures flip and the windage does not adjust. I also notice when I turned the elevation knob that the sight is more wobbly than even a Bushmaster A2 sight. Anyone have any suggestions or thoughts? 
Added: The rear long/short range aperature looks as though it’s stuck to the windage screw.
Well, I’ll answer my own question here: 
I tried soaking the sight in solvent, but it really didn’t do any good. So, today Icalled LMT tech support and the guy said that he has seen that problem before and there’s nothing I can do to fix it myself. He said the problem was either with the screw being too tight or the windage knob. 
While LMT tech support couldn’t fix the problem over the phone, they were extremely prompt with returning my call and very friendly. N.F.A. Assets was very responsive and is refunding my purchase.
I’m glad to hear LMT’s customer service took care of you.
I have never needed it but I have always heard great things about LMT and their warranty.
