SureFire Suppressor Trainers are designed for use with marking cartridges (e.g., Simunition FX and UTM), training ammunition (e.g., SRTA), as well as frangible and live ammunition in a training setting. These trainers replicate the length, weight, and attachment of SureFire SOCOM Fast-Attach suppressors, enabling warfighters to train as they would in real combat situations during force-on-force training. Every SureFire Suppressor Trainer is manufactured in the U.S.A.
