At one point Leupolds CS was probably the best. It has been really watered down lately as has their QC. My gunsmith friend used to recommend them exclusively but that is not the way it is now. I'll tell you a little story and you can believe it or not I could care less. My best friend bought a MOdel 52(Browning) that had been customized with a match grade barrel a few months ago. On it was a Leupold 6.5-20x40 VARI-X III gloss finish , the scope looks extremely good considering however old it is,it was made around the time they were introduced and not sure of that time frame. Basically the scope will not hold zero and was sent back to Leupold. Leupold promptly called him and told him that parts were not available for that particular scope. Their solution was 579+ dollars and the scope and he would geta current production scope. He was not agreeable to that and in a week he recieved a new scope box with the old scope in it. Needless to say they lost a lifelong Leupold customer. Sounds like they have the BEST customer service to me eh.
