I bought a Nikon Monarch 3-12x42 (BDC) scope today, kinda spur of the moment. By that I just mean that I didn't do tons of research before the purchase. I'll admit I don't know a lot about scopes, I've mainly shot with iron sites. I've never used any scope with BDC either. I'm just curious what you guys think of this scope, did I get one that will work out for me in the long run?
