I'm trying to figure out which BUIS to get ... it would seem that most are adjustable for elevation and only a very few for windage. Is there any substantial advantage to being adjustable for windage???

Actually. I believe it is the other way around: most are made for windage but not for elevation - they use the front sight for that. If they weren't adjustable for windage, you would have a heck of a time trying to time the barrel to dial it in, shimming the rear sight to the rail or knocking the FSB into alignment with a hammer

Are you wanting a flip-up or a fixed BUIS? I really like the Tryo flip-ups. BUilt like a tank. Windage adjustment knob won't get accidentally "adjusted". Very fast to deploy.

For a fixed BUIS I love the LaRue. Doesn't take up too much space. Has adjustable quick release lever. QD lever is on the right side so it does not interfere with the charging handle.



agree with BH on the choices of buis

Duh (slapping my own head) ... I think I'm going to go with a folding back-up sight. I've a Aimpoint clone as the primary sight ... so the back-up will be just that if the battery goes TU.

Well, after reading the comments here on AR15 ... I placed an order for a TROY BUIS ... so, we'll see!
