Anyone used one of these now discontinued dust cover rails for an optic mount? I picked it up a while back but never liked how high the optic was mounted (admitted I was using tall red dot (Aimpoint Pro). I also questioned how well it maintained zero after removing the dust cover. I ended up taking it off and going back to iron sights without even shooting with it.
Anyone had success holding zero with this type of mount?
