The Systema Energy line of internal AEG upgrade parts are the first ever complete line of lightweight, energy efficient, airsoft gun enhancements. The Energy line from Systema was designed to do two things, reduce player fatigue and reduce parasitic drag from the gearbox's moving components. According to Systema, "a quantifiable weight reduction in the weapon platform can be achieved," by completely changing all of your internal gearbox parts to Systema's Energy line. That is where this Energy Head Set fits into their design; the piston and cylinder head are lightened to reduce player fatigue and parasitic drag from the drive train. The cylinder head is lighter and comes with 1 regular nozzle and 1 bore up nozzle, and the piston head is lighter and comes with 1 rubber and 1 silicone o-ring. Since the cylinder head nozzles are interchangeable there is no need to buy a completely new cylinder head if you decide to upgrade your cylinder to a bore up type. Also, since the piston head comes with two o-rings the gun it's installed in will work in a wider range of weather. Not only is this head set energy efficient, it's cost efficient, and cold weather friendly as well.
Package Includes: cylinder head, regular nozzle, bore up nozzle, piston head, rubber o-ring, silicone o-ring
