Re: AR Flip-Up sights
I'm just curious . . . . . . with the range-adjustable front and rear sights available, someone thinks that dialing range to a target is feasable on a combat weapon. How many of you have actually dialed in the range anywhere other than a KD range on irons? If so, how did you figure out that range? Did you hit?
Just curious. I always thought of a BUIS as an emergency replacement to my optics should they fail. Tinkering with elevation while a bad guy is standing withing your line of sight (and hoping he doesn't either shoot you or just leave) seems to me to be an unholy sin. Chances are - if you can see him fairly well - he's within your zero range and you should be launching lead at him.
Adjustable elevation backup iron sights are a KD range toy IMHO. But if anyone out there has personally put holes in someone using one, I'm willing to get educated on the matter. Otherwise, a simple, sturdy same-plane rear (Troy, Magpul, MI, ARMS, etc) are what you should be looking at.
