I had one of the first Nikon Monarchs to come out (3-9 X 40). Compared it in the store to all the Leupold models. I was going to buy the best scope (other then big $$$ German) and ended up with the Nikon.

Those were the truest adjustment knobs I ever had. Precise clicks that moved the poi exactly what it was supposed to. The horizontal adjustment did not interfere (change) the vertical adjustment and vice versa. NEVER heard of having to "tap" them to make them move.

I had that scope for 15 years. Still is one of the best I've seen. My brother has it on his best rifle right now.
