Hey sorry it took me so long to get the optic mounted to one of my rifles but I got it mounted and zeroed today! It worked very well I am very pleased with it. The only things I would like to see changed would be for the dials to be more tactile and a bigger fiber optic on top. The fiber optic works......if your in direct sunlight for right under a light bulb, if not you will have to go to the battery. But overall i think it was a good purchase on my end and if your thinking about getting one go ahead and try it out.
