"While the Burris Fast Fire II has been good so far, the III model is a better way to go."
had all three; the three is better for battery replacement (do not need to remove it from the gun to change them), I prefer the two with just on & off vs. the three's range of on including one so low I have to look at it in the dark to make sure it is off, Both are water-resistant (the one was not).
