The APS Silver Edge gearbox is yet another step forward with improvement of the tried-and-true version 2 gearbox. APS took their Hybrid Electric Blowback gearbox design and improved upon it with some excellent key features. First and foremost they use an improved strength zinc alloy for the gearbox shell material. They then fully polish the interior of the gearbox to a chrome-like finish, effectively reducing friction on the moving parts that contact the gearbox walls, such as the sides of the piston and the tappet plate. From there they deck the gearbox out with steel gears riding on 8mm stainless steel bearings, low-resistance wiring and trigger switch, and to top it all off a Quick-Change ball bearing spring guide allowing for easy spring changes in the future. All of these improvements net around a 15% increase in overall efficiency, when compared with standard Ver2 gearbox designs. What this means for the user is better battery life, smoother gearbox performance, and improved gearbox longevity.
