Lots of assumptions in that answer...like assuming that retreat is a possibility.
Or that the fight is over because you decide it's over.
If you don't give yourself options...you won't have any options.
Lighthearted snide remark: Lots of failure to read here. Maybe some backup eyes are an option worth looking at.
In all seriousness: Switching to pistol. Point shooting with failed/broken optic. Disengaging. I don't see where there weren't options listed, in response to what is already a highly improbable scenario for me: engaging a threat at distance with an AR, when I have an optic fail, necessitating the use of BUIS.
If I'm using a $60 chinese red dot, back up irons are a damned good idea. If I'm using an ACOG, optics failure is pretty low on my list of worries. Not to mention that from reading stuff from people who would know, the failure rate of rifles themselves has been much higher than the failure rate of ACOGs during the GWOT, so I guess I should really be carrying a second AR instead of BUIS.
You and many other disagree, and that's fine. I see BUIS in the same way I view DA/SA pistols. They're not a bad way of doing things, but the main reason they exist and continue to be popular is hold overs from old ways of doing things who wanted some sort of comfort blanket to aid the transition. Folks used to revolvers liked a long DA pull on their newfangled semi automatic pistols, folks used to iron sights want that as a back up option to quality optics. Meh. Use them if you want to use them, but I don't view them as a must have item at all if you're using an ACOG.
