At launch in Jan we plan to have 3 different types of 30mm mounts, 4 types of 34mm, black anodize and the DDC shown in the picture, 0 MOA, 20 MOA versions and mounts for the Aimpoint T1/T2, Trijicon MRO and others.
There are also two aluminum alloys available. 7055 Aluminum which is a stronger 7075 and also Alcoa's 2099 advanced Lithium/Aluminum alloy which is as strong as 7075 but lighter, stiffer and more corrosion resistant. 2099 is used in highly loaded airframes by Boeing and Airbus and is considered the cutting edge of aluminum alloy development.
Mount cost is around $350
