The Kastle Fortress Diving Board is a clear mount built to fit 2.26" Fortress Series optic mounts. It lets you attach a laser, thermal unit or other device in front of your optic, which saves rail space farther forward. Because the device sits ahead of the optic, smaller platforms without much real estate out front still have room for one. The M1913 Picatinny section means it works with most major thermal and IR/Vis laser platforms.

The mount is machined from 7075-T651 aluminum and finished in Type III MIL SPEC hardcoat anodizing in clear. Kastle machines its Fortress series mounts in its own facility, and this one is made in the U.S.A. Kastle backs its machined mechanical products with a lifetime warranty against defects in materials or workmanship. Keep fastener torque moderate, since excessive torque can damage mounts or optics.
