I bought a Lyman 57wjs aperture sight in January from Midway and just recently had it installed on a Rem 700 ML. The sight is sloppy in the vertical adjustment slot and moves when touched up/down, left/right. I opened ticket with Lyman a couple of weeks ago and sent a video. They couldn't open the video and requested pictures via email. I sent four pictures as an attachment and they said they won't open and would I send them in a file which I did a week ago. I finally called them and the guy said they couldn't help me if I didn't know who I was speaking with via email. The email has no name other than customer service. I next sent an email requesting the name of the person I have been dealing with via email, no response. I'm running out of patience but don't know what to do, call Midway? The pictures that I sent all opened fine from my sent email.
