Every airsoft gun tuner can relate to that victorious feeling when, after an upgrade, the gun’s sound is a crisp, clean, and immediate cycle. The spring plays the most important role in building the gun’s performance; it generates consistent muzzle energy and determines the load on the motor.
Atom Custom Momentum springs are linear springs made from high-quality spring steel. A linear spring provides consistent muzzle velocity and an even load on the motor regardless of how much the spring is compressed. A linear spring also limits overspin better than a non-linear spring, as it absorbs more of the gear train and motor’s excess kinetic energy at the early stage of compression compared to a non-linear model. For this reason, a linear spring reduces overspin more effectively than non-linear springs. We particularly favor linear springs because they are best suited for pre-cocking setups; the AEG spring creates the demands on the motor, which can slow down the rate of fire and increase trigger response time. The benefits of a linear spring are most evident in pre-cocked setups, as the load it generates remains consistent; this ensures the motor experiences the least possible strain. In turn, this extends the motor’s lifespan and improves battery endurance.
Momentum AEG springs are especially suitable for electric guns, as they work well even with high-torque motors. The linear design helps reduce the overspin often caused by powerful motors. When tuning an AEG, a linear spring allows you to keep the load generated by the spring as low as possible throughout every stage of the cycle.
The power ratings of the springs are indicative. The actual power depends on factors such as the amount of pre-compression, barrel length, BB weight and surface quality, as well as the air seal of the gun’s internals.
