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.\u003c\/p\u003e\n\u003cp\u003eAtom 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 generated by the spring remains consistent; this ensures the motor experiences the least possible strain. In turn, this extends the motor’s lifespan and improves battery efficiency.\u003c\/p\u003e\n\u003cp\u003eMomentum 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.\u003c\/p\u003e\n\u003cp\u003eThe power ratings of the springs are indicative.

Each Impact cylinder head comes with a factory-installed Sorbothane® shock-absorbing pad. The Sorbothane® pad helps prevent gearbox shell cracking thanks to its excellent damping properties. The Impact cylinder head also corrects the piston’s angle of engagement (AOE) with the sector gear. Due to this AOE adjustment, the piston must be compatible with the modified angle. For best compatibility, we recommend using Atom Custom Fusion series pistons with Impact cylinder heads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCNC-machined from aluminum\u003c\/li\u003e\n\u003cli\u003eTwo O-rings ensure a perfect seal with the cylinder\u003c\/li\u003e\n\u003cli\u003eSorbothane® pad protects the gearbox\u003c\/li\u003e\n\u003cli\u003eAdjusts piston angle of engagement (AOE)\u003c\/li\u003e\n\u003cli\u003eDamping pad and Sorbothane thickness: \u003cstrong\u003e5mm\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCompatible with Atom Custom Fusion pistons\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNote: The color of the cylinder head may vary by batch.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is Sorbothane® and how does it work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSorbothane® is a modern rubber-like specialty material developed in the UK, used in everyday products such as high-quality running shoes and industrial applications.
