Be very careful when buy night sights from Optics Planet. I ordered a set of the green/yellow night sights and had a gunsmith install them. Ok, no problem. The problem was after the install while inspecting the work I found out that what Optics Planet called green/yellow was that the front sight was "outlined" in yellow but the sight was green. NOT WHAT I WANTED. Called customer service but their only solution was for me to take them back to the gunsmith and pay to have them removed (another $40) and return them. Shipping was also at my expense. So now I am stuck with a product that was not what I wanted. Live and learn. I will now call Optics Planet if I ever order anything from them again to make damn sure I get the product that I want. So don't believe all of the descriptions you may read on their site.
Pros: can be used in no or low light
