The Geissele Super Precision 34mm DDC Scope Cap Diving Board is a robust accessory interface designed to replace the standard ring cap on a Super Precision 34mm mount to give you a full-length 7-slot Picatinny rail for mounting rangefinders, laser modules, magnifiers, and other accessories alongside your optic without sacrificing zero or stability. Machined from 7075-T6 aluminum with a DDC (Desert Dirt Color) hardcoat anodized finish, it includes enlarged hardware and an additional ring clamp to broaden the bearing surface for a secure attachment. With a centerline height of 1.68 in from the bore to the top of the rail and an estimated usable rail length of around 4.20 in, it provides a highly versatile mounting platform while preserving the integrity of your scope setup.
