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 these Energy 6mm Oil-less Metal Bushings fit into their design, they are slightly lighter than other metal bushings to help reduce player fatigue.
Package Includes: 6 bushings
