The ASP Defender D2 TEST Insert is the inert TEST/ training cartridge for the ASP Metro Defender D2. This Insert is compatible with ASP Metro D2 Defenders and Sport D2 Defenders, and contains approximately twelve 1/2-second bursts. Unlike common throwaway aerosol can defense products, ASP Defenders are highly-engineered dispersion devices that use a proprietary, replaceable OC (Oleoresin Capsicum) Insert. These Inserts are precision-machined from aerospace aluminum and solid brass, and incorporate a specially-produced valve system and patented dispensing mechanism.
