This version Systema Professional Training Weapon guns feature a whole a whole array of improvements over the older versions. The control board and ECU have had comprehensive full-scale revisions and a new addition to this model is an LED feature to the S.E.C.U., which indicates the present state of the PTW during engagement. It may sound like a minor thing, but it can be used to determine the condition of the PTW; when to change the battery, to any serious issues with the PTW.
Even though the PTWs before this version had a superb trigger response for rapid shooting, the response time has been improved for this version. The trigger reaction program has been changed in Micro Second increments to allow a crisp trigger response.
