ZCI M110 Tune-Up Spring

Looking for a little extra power for your shots? Need a spring with a little more punch? Try out the ZCI M110 Tune-Up Spring. This spring is designed to fit most Marui-Spec AEG gearboxes, and offers a more tense spring for some stronger shots. In a standard 14" barrel AEG system, a 110 spring such as this can get you close to roughly 375FPS, but be aware that other factors will likely affect this approximation.
