The core technology that made the XREP projectile possible is its electronic "engine." A stunning engineering achievement, the XREP engine provides the same bio-effect as our field-proven X26, but from an electronics package that weighs only 3.4 grams and consumes less than one tenth of a cubic inch. In order to achieve a wireless projectile, the battery is fully integrated into the chassis and provides the power to drive the XREP projectile engine for its full 20-second cycle. The XREP cartridge comes pre-packaged in a shell that is compatible with most existing smoothbore and rifled barrel 12-gauge shotguns. The transparent shell ensures officers properly identify the XREP cartridge prior to loading it in the shotgun. As the XREP cartridge is deployed, a ripcord attached between the shell and the projectile activates the projectile. Once activated, the XREP projectile is “live” as it comes out of the barrel. The XREP projectile autonomously generates neuromuscular incapacitation for 20 continuous seconds – enough time to close the distance and take the offender into custody without risking injury to officers. Not only does the XREP projectile incorporate a revolutionary electronic payload, it also incorporates a radical new spin stabilization technology to maximize accuracy. As the XREP projectile leaves the barrel, three torsion spring fins deploy, causing the projectile to spin, even when launched from a smoothbore barrel, providing superior accuracy and flight stabilization. The TASER XREP projectile launch velocity is approximately 260 feet per second. The nose assembly of the XREP projectile contains four forward facing barbed electrodes. On
