The Kastle DB-193 Diving Board is a forward accessory rail that mounts ahead of your optic, so a laser, thermal or other device sits out front and saves rail space further forward. It is designed to work with the MICRO-193, ACRO-193 and AEMS-226 optic mounts, and it fits 1.93" Fortress Series mounts, but it is not compatible with the AEMS-193. That extra forward space helps on smaller platforms that lack real estate out front. Its M1913 Picatinny interface fits most major thermal and IR/visible laser platforms, including MAWL, DBAL, NGAL, RAID-X, RH-25 and Skeet IR, so you have plenty of devices to choose from.

The body is made from 7075-T651 aluminum and finished in black Type III MIL SPEC hardcoat anodizing. Kastle makes it 100% in the U.S.A. as part of its Fortress line, which it machines in its own facility. Kastle gives machined mechanical products a lifetime warranty against defects in materials or workmanship, so keep fastener torque moderate, since excessive torque can damage mounts and voids the coverage. Black is one of five anodized colors, alongside Flat Dark Earth, Desert Sand, Clear and OD Green, so you can match the rest of your build.
