yondering with the auto adjustable brightness models if your using a high lumen tactical light and the dot has a gotten dim in the dark, once you switch the light on does the auto adjust bring the dot illumination up fast enough? I would think it would be faster than you could pull a trigger but just wondered on the RMR if light on, shoot instantly was possible.
The adjustment is not quite instantaneous, but takes just a few milliseconds, ie faster than you can react, IME.
I have heard/read guys saying they take something like 10 seconds to adjust; that's flat out wrong and I can only assume they've either got a broken optic or they read and misunderstood the technical specs.
Guys, the BUIS are not just there in case the optic breaks. There's a lot more to the co-witnessed sight system than that.
