Kastle Group FSM-193 FORTRESS™ Scope Mount<\/h1>\n

The Kastle Group FSM-193 FORTRESS™ Scope Mount<\/strong> is built for shooters who prefer a taller optic height without sacrificing rigidity or repeatable performance. Featuring a 1.93-inch optical centerline<\/strong> and 0 MOA cant<\/strong>, the FSM-193 is ideal for modern LPVO setups, red dot magnifier combinations, and rifles configured for use with night vision equipment. It is available in 30mm and 34mm ring sizes<\/strong> and incorporates Kastle Group’s premium FORTRESS™ architecture.<\/p>\n

Precision machined in the USA from 7075-T651 aluminum<\/strong>, the FSM-193 utilizes Kastle’s innovative Titanium K-CLAMP™<\/strong> mounting system to provide exceptional clamping force, return-to-zero capability, and long-term durability. Integrated KNEKT™ modular attachment slots<\/strong> allow users to expand their rifle with compatible accessories while maintaining a lightweight, rigid mounting platform.<\/p>\n

The elevated 1.93-inch centerline<\/strong> promotes a more natural, heads-up shooting position and provides additional clearance for helmet-mounted night vision, gas masks, hearing protection, and other mission-essential equipment. Whether you’re building a duty rifle, SPR, competition gun, or modern sporting rifle, the FSM-193 offers outstanding ergonomics without compromising strength or precision.<\/p>\n
