i have the 3x9x50.it has been great so farvery clear.thete is a problem with these models for some reason.the side to side adjustment often locks up.i did some research and found this is only happeneing with this model.i tried for 4 months to get nikpn to sen me the info about this problem.it has now been 6 months and still nothing.the only prob i find is that i wish it was just a haor more clear.in bright light it really distorts.i have mine on a ruger1 30.06
