I did get the Low Profile version. It's still a tad higher than a Magpul MBUS but I like it. I've never bothered to shoot it farther than 50. The larger ghost ring is definitely fast and accurate enough at 25 at minute-of-man accuracy.
It will be interesting once that Silhouette comes in. I really do only want to use them as back ups and ordered that Silhouette so I could fold it down. On my Lucid HD7 the A2 sight is prominent in the lower-third. On my Leupold MK2 at 1.5x or 4x I don't notice the A2 sight at all.,
