SureFire 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. Every SureFire Suppressor Trainer is made in the U.S.A.
