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. The program was designed with the 490 type motor in mind, which Systema have adopted for use with all their models. Other revisions include: -Improved Burst Function - instead one trigger pull releasing 3 BBs, with the right control, in burst mode, you can release 1 or 2 BBs. -Changes to the Trigger Switch - 2 Stage Trigger; by using an even shorter stroke, the PTW mimics the trigger travel of a real firearm. -Improved longevity of the FET, with a reduced power consumption, improving the efficienct by three times. -Incorporation of a Tight Inner Barrel for all models - Systema have decided to adopt the 6.04mm inner barrel for all models. -Changes to the Air Seal Packing - changed from conventional air seal packing to an O-Ring. -Change in the Piston Head Guide Sleeve - Improved Torque -Standardization of the Cylinder Unit - Since 2007, Systema have standardized the Cylinder unit of the M4 versions for greater expansibility
