Lonex AEG V6 P90/V7 M14 Enhanced Steel Bearing Spring Guide (GG10-06)

This is an exceptional design and material this spring guide can easily counter the pressure of the gun spring when it contracts, by its spinning the shaft of the spring guide. This feature can also boost the effectiveness of the springs and reduce the chance that the spring snaps during high-speed movement. Lastly, it helps to reduce the resistance of the spring; thus, this allows the battery to last longer.
