Description from the old March Optics USA website:
These aircraft grade 7075-T6 Aluminum rings have the strength of steel at less than half the weight and are machined in matched pairs to ensure precision alignment right out of the box. March rings are meticulously made and anodized black, creating a finish that perfectly complements the finish of your March scope. Each scope ring had a special groove cut on the inside that basically created two "mini" rings in one. Therefore you end up with four points where the scope is held securely in the rings. Often, lapping is eliminated due to the extremely precise matched machining.
The CNC machined logo on top of the rings ties the whole look together so you end up with a flawless optical package that will stand out from the crowd with its sharp appearance and impeccable performance. You chose a March scope because you want the best. Now, you should make the most of your investment with top quality March scope rings. Specially designed to fit March 34mm scopes, height is 1.100".
