Spring G&G M120 AEG

This G&G M120 AEG spring is compatible with AEG airsoft replicas and it’s intended for tuning the replica’s speed. This can either be an upgrade or a downgrade, which might be needed to meet requirements. The G&G M120 AEG spring is non-linearly wound. This means that some of the coil windings are closer together than others. The coil windings that are closer together create less resistance than is the case with the windings that are further apart, which means the spring requires less force to be compressed. This means that the teeth of the piston -which is located in the gearbox- have to endure considerably less stress.
