SureFire's Suppressor Trainers are intended for use with marking cartridges (e. g. Simunition FX, and UTM), training ammunition (e. g. SRTA), frangible and live ammunition in a training environment. The SureFire Trainers mimic the length, weight and attachment of SureFire SOCOM Fast-Attach suppressors, allowing warfighters to train as they would fight when participating in force on force training scenarios.
