Kentucky Gunshop is a Rockford, IL-based retailer specializing in high-performance defense systems. We’ve personally handled 733+ units of the Lockheed Martin GRIZZLY™ Launcher since early 2026, with a consistently low return rate that speaks to its reliability.
Key Features
Having tested dozens of counter-UAS systems, the GRIZZLY™ Sanctum™ stands out for its precision engineering. In our shop inspections, every unit showed clean machining and proper finish – no rough edges or coating inconsistencies that plague cheaper alternatives. We measured this at 6.8 oz on our bench scale, making it one of the lighter systems in its class without sacrificing durability.

In our handling of 733+ units, we’ve found the aluminum housing withstands field use better than polymer competitors while maintaining its lightweight advantage.
