Ive been meaning to take the time to tell others my opinion about the Sightron Big Sky 6 x 42 I received about a month ago. Please keep in mind I dont have a lot of experience with many (especially high dollar) scopes but Ive been through my share of lower to middle priced/class scopes. This is the most expensive scope Ive ever purchased and I simply love it so far. I will admit that the Nikon Prostaff runs a pretty close match to it when you compare and consider the price difference. The Sightron is clearer than the Prostaff though and where I really noticed a difference is there is a lot less glare on the lens in early morning and late evening compared to Nikon. I was really impressed when after bore sighting how this scope changed my point of impact exactly according to how many clicks of adjustment you give it. I think some of you know what I mean when you adjust a scope and it takes a round or two until the scope settles to a spot and such. well this one is the only one that Ive ever owned that moved exactly the way it should have in my opinion. I have owned lower end priced Simmons, Leupold, Nikon, Bushnell and this is a good scope in my opinion. I dont have a lot of time and money but I really believe and wish that I would have taken the time to compare the Nikon Buck Masters scope because as good as I believe the Prostaff is then the Buckmasters would have run a close race. Some time ago I contacted Sightron via email and asked the difference between the new Big Sky scopes and theyre other scopes and this is the reply I got...
