imr, I have the Monarch 4X16X42 mildot Nikon on a 25 cal rifle. It has functioned correctly for the seven years on the rifle. I had an older high end Nikon Monarch which lost windage adjustment. I called Nikon, received a return label, sent it back. A week later a call from Nikon to ask which of three equal value new scopes I would like. They sent me the new in the box $959 scope FedEx overnight to replace the one I had returned. What I like, no questions, no hassle, no waiting for weeks, integrity, excellence of service and repair or replace. I now have purchased another Monarch which I haven't any negative issues. Bushnell, from the several I've looked through I'm not impressed. Just my personal experiences for what it's worth. Good luck.
