My two main rifles I use Knights armament. Same as on my duty weapons. Not cheap. Hard to get. I also use the Magpul MBUS Pro on other rifles. They are also great. My less important rifles range/toys I use the Magpul polymer sights. Never had a problem with those either. But I agree. When it really counts, use metal sights. Flip up or stationary. At the end of the day, they are just back up sights. And I am pretty sure I can drop bad guys with no sights if need be! ;)
