In this case, it wasn't a loose screw so much as a poor decision by the manufacturer to not use a detent on it. However, the reality is that I'm probably going to put an optic on it anyways, probably with a Scalarworks Sync. Ghost ring is nice, but nothing beats a red dot.I wouldn't worry about that too much, I mean I finally shot that LTT 1301 and the front sight was loose and every screw on the CROM mount was loose after about 20 rounds. All three mounting screws and the both windage adjustment screws were hanging, very lucky not to lose any.
