I kind of stumbled into a gun with a rail mounted front sight. I'm running MBUS (front and rear), with the front sight mounted on a 12" midwest industries free float rail. I expected some sort of fairly tangible accuracy issues. If anything I've been quite impressed with how good the accuracy is. I'm not a bench rest shooter, and I don't think anyone else here is either....

I do plan to upgrade to a set of DD fixed sights soon, for duability, and because i think fold down sights are silly with no optic. (goin into point shoot mode! click click)

So what's so bad about this kind of setup? A quality fixed sight on a rail isn't going to break off or come loose. The other side i guess is gas blocks... I'm currently running a spikes set screw block... not the best setup, but there should be no issue with a pinned cut down sight or a good clamp on block.

just looking for opinions...
