Aimpoint 30mm standard mount for CompM and PRO optics

This is a low-mount ring which rises 1.55" above Picatinny Rail, which is normal Aimpoint height

This mount is just a little higher than absolute co-witness and a little lower than 1/3 co-witness.

> 30mm ring and base for CompM2, M3, M4 and PRO, part number 12194
