I used to have a cheap side rail and nc star red dot on my ak that was dim but it worked. I gave that rail to a friend and got a utg quick release side rail. I have it on very tight but there's only one bolt in the middle vs the two my old one had. I've recently tried a truglo reflex and a 2x truglo tube sight. With both, I'd shoot a few rounds and my poi would vary significantly after a few shots. I thought maybe it was my cheap optics and find a trs-25 on sale, and I've had the same problem. I think I physically saw the dot drop down some right after my last shot. It shoots just fine with irons. I'm wondering if my mount Is the problem because the trs25 is supposed to be a decent optic. Has anyone else had this problem?
