I have not personally had an opportunity to shoot this reticle, but would likely have bought one had it been available when I bought my last Holosun. Years ago I used a Trijicon Reflex with a 12 MOA triangle on an AR and liked it a lot.
I have a number of Holosuns on various handguns, and have had zero complaints about the sights themselves.
Here's a review of the Holosun / ACSS Vulcan by Aaron Cowan of Sage Dynamics. He literally 'wrote the book' on modern handgun optics.
