I put one on my SP-10 for this season. Son killed a nice tom on youth day with it this past Saturday. Seems to hold zero well, easy to use, set up, adjust... It does sit a little high, and that takes a little getting used to. I put some black pipe insulation on my stock to give me a face-touch reference - works fine. I have noticed that the POI changes a little with each reticle, so what ever you use to sight it in, stick with that for hunting. I'm not sure if that is due to the projection of the reticle on the lens, or if I end up aiming in a different spot based on the reticle - but I use the open circle and like it a lot.
