I've got two milled Glock slides and am running Trijicon RMRs on both of them. Recently they each have started to "wink out" on me while I'm shooting them. No, I'm not just "losing the dot" they literally are either just dimming or going out altogether. I'm pretty pissed off since I have nearly $900 tied up in RMRs with these things.
Is this common?
