The Kastle Group FSM-154 is a scope mount for Picatinny rails, machined in Kastle's own facility with decades of defense and aerospace manufacturing experience behind it. Its 1.54" optical centerline sets how high your scope sits over the rail, and the zero MOA angle means the mount builds no extra tilt into your setup. The mount fits 30mm tube diameters, so it pairs with scopes that use that tube size. Kastle says it was designed with input from military, law enforcement and competitive shooters.

Titanium K-CLAMP mounting is how the FSM-154 attaches to your rail. Kastle KNEKT modular slots are built into the mount. The body is machined from 7075-T651 aluminum and finished in a black Type III MIL SPEC hardcoat anodized coating. The mount is made in the U.S.A.
