I have owned several Nightforce scopes. I have a 3.5x15x50 with a zero stop and high speed it is the npr1 recticle. My question is my recticle isnt dark enough and I have tried to focus my scope and It just doesnt get any darker or clearer. I have compared it side by side with my 5.5x22x50 and another 3.5x15x50 and it just isnt even close to the others. Any thoughts or ideas?
