The ASP Defender LE MK-4 Inert Trainer, Stream (ASP part no. 55120) is the inert training version of ASP’s Defender LE MK-4 stream police OC aerosol. Form factor, functionality and performance (range and capacity) match the live spray, but there is no OC in these blue-top canisters. That allows uninterrupted training, indoors or out, with full operational realism and without exposing trainees to live agent. The actuator has a flip-top safety, and canisters carry production and lot data, a serial number and an expiration date. Defender LE is made in the USA by ASP.
