Tienly Super Rotary AEG Bearing Spring Guide (V2 / V3) Gearbox:V2 Windage and elevation adjustable dotTienly bearing spring guides feature high quality ball bearings which allow the spring to rotate during compression and release freely. This alleviates binding of the spring and alleviates torsional strains on the spring leading to more consistent FPS. The inherent thickness of the ball bearing assembly will also act as a spacer for the spring, mildly increasing FPS.
