I had Springfield check out my sight adjustment knobs when my rifle was sent back for other warranty problems because I read on here about the issues people were having with them. They replaced the elevation knob and it feels nice and tight and the adjustments are crisp, but my windage knob seems to have a little play to it. It still takes some effort to make an adjustment though. I tried tightening the screw in the center but it appears to be tightened all the way. Is this slight amount of play normal on the windage knob or should it be completely tight like the elevation knob? I don't see my sight adjustment getting out of whack because like I said it still takes some force to adjust it. I just want to make sure everything is how it's supposed to be. Thanks!
