I have a few. You wont be able to tell much difference in the monarch and buckmaster in the store. Take it outside. The monarch is better glass. I like my monarch. I have a 5-20X44. It is very clear even on 20 power. I dont think you can go wrong either way between Leupold and Nikon for quality. I will say that Leupold has the best warranty hands down. Sometimes that is worth the extra few bucks in the long run.
This is good news, I just ordered the 4.5-14 SF Buckmasters for my 7mm... Can't wait!!
