it's not all it's cracked up to be, when you only have an indoor range.
unless i stand outside the shooting port, a HUGE NO-NO at my club, then the normal stance inside the port, i am past the light above, rendering the optic useless.
in fact, so useless, twice in the past, guns i have, the optic fell out, and i didn't even notice it until i got home. but i still blasted the targets into oblivion, as if i had an ordinary sight.
