I have been using their DMS for a while now. It the one listed in the post above. I have it on an ar now. I has been great. I started it on a 44 mag rifle. It worked well but was too big for the overall package (my opinion). On the AR is has been wonderful. Magnification range is good for the distances I usually encounter. I really like the circle dot reticle, though it took some study time with the subtension guide to fully utilize its capabilitys. I have also kicked around the idea of using it on my shotgun, as the circle would corelate well to the pattern with some of the loads I use.
As for performance of the scpoe, the adjustments have been right on. The glass is very good for the price. The illumination will go low enough to use at night. Also, my particular scope took a pretty good fall to hard surface and is still doing fine. Only a very small scratch in the finish of an adjustment cap.
