I found a nib nikon monarch ucc 3.3x10x44 AO for $275. Is this a good deal? How about the quality of the scope?

GRAB IT QUICKLY! It won't last long at that price. The best price I know of for this scope (matte/Nikoplex) is $345 at www.theopticzone.com.
The optics feature incredible resolution and low-light performance that has to be seen to be appreciated. It is one of my favorite scopes of the entire Monarch lineup.

I agree with Bob. It is a great scope and at that price I would not pass it up. Actually where might this scope be, I may have to purchase it since that is well below my cost.

Be careful that bargain Nikon is not "factory refurbished". I see a lot of them advertised and the warranty is only a year I believe.
