Highbridgearmory is a Owensboro, KY-based retailer specializing in high-performance defense solutions. We’ve moved 356+ units of the GRIZZLY™ since Q1 2025, with customers consistently praising its reliability.
Why This One?
Having personally inspected multiple units, I can confirm Lockheed Martin’s GRIZZLY™ represents a significant leap in counter-UAS technology. The Sanctum™ system’s build quality exceeds typical commercial standards – we found no tooling marks or rough edges during our evaluation. At 2.2 oz (measured on our bench scale), it maintains an ideal balance between durability and portability.
