The new PTW EVOLUTION cylinder casing is now made completely from one piece of SUS304 stainless steel (84g) rather than the aluminum casing (48g) on previous revisions of the PTW.
The stainless steel cylinder casing is much stronger, thus resistant to deformation caused by minor drops, and dents caused if a stray BB is caught between the cylinder casing and magazine while reloading.
Systema Retains the power level color coding of cylinders via a colorized metal inlay plate on the top of the cylinder.
The stainless steel cylinders of the latest PTW EVOLUTION contains the same internal parts as the previous version of the PTW, which means complete compatibility with existing PTW piston, cylinder head, springs, spring guide and all other parts. The already perfected ease of maintenance of the PTW cylinder is preserved in the latest EVOLUTION model.

A lot of Systema MAX PTWs out there do not have an ambidextrous fire selector. There is no need to worry about that anymore!
This is the new gearbox from Systema that has an ambidextrous design element to it so you can switch it out with the older system and apply this to your PTW! It also comes with a fire selector so you don't need to worry about that. Hoorah to left handed use!
