The Guard Dog Knightro just may be the strongest built stun gun in the world. Made with type III aluminum alloy and a ridged enforced body throughout, the Knightro can withstand impact to almost any degree imaginable. Run it over, drop it, use it to shatter glass, or for self defense purposes, the body will stay intact and is ready for immediate action. Equipped with the world famous and Guard Dog Exclusive Concealed Inner Stun Technology™, there are no visible prongs that hinder the output of the flashlight and allows the stun gun to be disguised within the outer layer. With a swift action, the Knightro blinds any attacker with 300 lumens of pure white light. With a reach spanning further than 2 football fields, the built-in tactical flashlight switches to 3 alternate light functions: high, battery-efficient low, and emergency flashing strobe. Whether the Guard Dog Knightro is used for daily operation or by security professionals worldwide, trust a name backed by the leading tactical self-defense brand in the world.
