The Kastle Group FSM-154 is a scope mount for 34mm tube diameters that attaches to a Picatinny rail, so your scope sits in a mount sized to its tube. Kastle machines it in its own U.S. facility from 7075-T651 aluminum, drawing on decades of defense and aerospace manufacturing experience. The zero MOA angle means the mount adds no built-in tilt to your optic. Kastle developed the FSM line with input from military, law enforcement and competitive shooters, and field tested it in different environments.
Titanium K-CLAMP mounting is how the FSM-154 locks onto your rail. The mount also carries Kastle KNEKT modular slots as part of its design. The finish is Type III MIL SPEC hardcoat anodizing, shown here in Flat Dark Earth.
