Interesting new rear sight for ARs from Troy--instead of a round aperture, it's a diamond shape. Troy claims faster target acquisition than with a round aperture. Found at the Firearms Blog:

Wow. That looks really nice.

The principle seems sound. The Steyr M9 and M40 pistols have trapezoidal sights and they work very well. I find I can align those sights better and more quickly than any other kind of handgun sight.

We had the guy who thought up that trapezoidal sight as a visitor to the old forums a couple of years ago.
