Lonex M150 Enhanced AEG Spring - 480-500 FPS
Oftentimes, out-of-the-box AEG springs tend to be low quality and wear down relatively quickly. As the spring cranks out BBs, it will begin to loose elasticity which will negatively impact your muzzle velocity and the overall performance of your AEG. The Lonex M150 Enhanced AEG Gearbox Spring is made from non-linear steel, which is great for mitigating operational wear and retaining elasticity far longer than stock AEG springs. This gearbox spring upgrade generates a muzzle velocity around 480-500 FPS (w/ 0.20g BBs) and also minimizes unnecessary strain on the battery and stabilize muzzle velocity.
