Anyone here use this? It looks like a pretty good buis with elevation and windage

I got one from Brownells, the quality is great.  I am still waiting to use it on a build.

 Ive got two of them, one with the spring loaded pop up and one manual.

 I put them on the two M4A3s my son and I have.  We like how they have the windage  adjustments.  But they are not cheap.

I had one, but I didn't like it. The rear sight was fully adjustable, but it didn't have a solid lock-up when flipped up. It would wobble back and forth a little.

Waaaayyy to overcomplicated and designed for what it is suppose to do.... which is be a BACK UP iron sight.
I know some guys like to be able to have all the dials and knobs and  have it adjustable in every direction.

But that defeats the purpose of a Back up redundant system. you want some thing that will work when all else fails.

Plus it has the price to go with the name.....

Plus the marketing  Dept. remembered to incorporate the Catch phrase "Combat" in the title of there sight, so that you would know what it's primary use is for......

There is a much larger list of who DOES NOT use these then does.... that should be your first clue....

 so I guess you wrote that review to say you have never used one ?
