The gearbox version is crucial because it determines compatibility with specific Airsoft gun models and upgrades. Version 2 and Version 3 are the most common, each designed for different replica types (e.g., M4s typically use V2, AKs use V3). The best version depends on your Airsoft platform and upgrade plans. A variety of versions allows for more customization and ensures you can find a gearbox that fits your replica perfectly. For example, the RETRO Arms CNC Split Gearbox V2 with Internal Hop Up Chamber is a V2 gearbox, ideal for M4/AR-15 platforms, offering enhanced compatibility and easy installation. Multiple gearbox versions are available so you can choose the one that best fits your build.
