Lonex M100 Enhanced AEG Spring - 330-350 FPS
Low quality stock AEG springs are notorious for wearing down over time. As the coils continuously expand and contract they loose elasticity and, as a result, your muzzle velocity will suffer. The non-linear steel used in the Lonex M100 Enhanced AEG Gearbox Spring resists this operational wear and retains elasticity for a much longer period of time. The design of this gearbox spring generates a muzzle velocity around 330-350 FPS (w/ 0.20g BBs) and also helps to stabilize the muzzle velocity generated by your AEG.
