D1 Insert, Test (Inert), Twin Pack

Precision, compatibility, and safety are the cornerstone features of the ASP D1 Inert Test Inserts. These proprietary inserts, intended for ASP Metro D1 Defenders and Sport D1 Defenders, are crafted from high-quality aerospace aluminum and solid brass. Each insert houses a specially produced valve system and patented dispensing mechanism, providing around six half-second bursts. One of the distinct advantages of this setup is its facilitation of safe training - using our Test Inserts that contain a harmless, inert aerosol. It's highly recommended to practice with the ASP Defender using these inert inserts before outfitting it with the active D1 Insert.
