drift, I've got the same ML you're going to buy. It's a Knight Magnum DISC .50 cal. synthetic/stainless. I put a Leupold VXII 2-7x33 on it and the results are incredible. I also used the Leupold QR rings and bases so I can take the scope off for cleaning; it does return to zero! I purchased mine through The Optic Zone. The owner, Jon, is extremely helpful and I urge you to check their website out and if you have any questions, don't hesitate to ask.
