eXtended Range Electronic Projectile

 

TASER XREP, the eXtended Range Electronic Projectile. XREP is a self-contained, wireless projectile that fires from a standard 12-gauge shotgun. It delivers Neuro-Muscular Incapacitation (NMI) bio-effect and can be delivered to a distance of up to 100 feet, combining blunt impact with field proven TASER NMI.
The battery is fully integrated into the chassis and autonomously provides the power to drive the XREP engine for its full 20-second cycle, enough time to close the distance and take the offender into custody without risking injury to officers.
