I've just looked close at those knobes...
<br>Almost pulled out my credit card, but after the guy installed it in front of me on Leupold scope , and after I inspected it very caryfully, It'd hit me! - I'm going to loose my "waterproof/fogproof" options! They're very well made, but there's a "O-rings" on original Leupold covers, and Stoney Points comes without it, and any humidity have the open way to reticles adjustment gear...
