Excellent sight.
I have owned three Swords now, and they have all been great.
Only con I can find is that they use a really soft metal for the tracks that the pins track on. Do not tighten the screws on the pins too much, or you will dent the metal, which will make getting a precise adjustment a little more difficult.
With that said, they are still the best sight IMHO. I use the Apex 3rd Plane Micro Matrix for both target and hunting.
