Advantages of spring guide with bearing

Reinforced with high-strength steel: The steel core easily supports heavy-duty springs (M90 to M190 and above). This prevents deformation or breakage, even under heavy upgrades.

Integrated ball bearing: The bearing allows the spring to rotate freely during firing. This reduces parasitic tension on the spring and limits internal heat.

Increased spring life: Precise guidance and bearing reduce wear and progressive stalling. Less unnecessary rebound and less loss of power over time.

Extended compatibility: Supports M90 to M190 springs, ideal for standard and moderate builds. Can also be used with higher springs, for occasional use.

Improved Rate of Fire (ROF): Smoother guidance reduces mechanical resistance in the gearbox. Result: a higher, more stable rate of fire (ROF), especially with Lipo.

Slightly increased muzzle velocity: Reduced friction and more constant spring compression improve efficiency. A slight increase in FPS is generally observed, especially with highly-tensioned springs.

Reduced mechanical friction: The POM outer sleeve rotates freely around the metal core. This limits heat in the gearbox and reduces the load on the motor and pinions.

Reduced energy consumption: Less friction means less strain on the motor and battery. This translates into more shots per load and longer motor life.

Easy installation, without opening the gearbox: The EVO 3 A1 spring guide can be installed without completely dismantling the gearbox. Simply loosen the retaining screw, change the spring and guide, then reassemble.
