There's a reason they're the gold standard.... - Leupold Standard Rifle Scope Rings

There's a reason why this brand is what all others are judged against when it comes to mounts and rings. They're very solid and the machining is excellent. Pro tip: resist the temp Tatian to put the front ring on your scope and use the scope for leverage to turn the front ring into its base. If the ring is tight, like mine was, all that you are likely to accomplish is to crush the tube on your expensive scope. A lapping bar would be best. I did not have the correct size bar available so I took a tip from a friend and used the plastic end of w screwdriver. Just try to find the closest size handle you can.
