The gearbox type influences upgrade potential, reliability, and maintenance ease. The Version 2 gearbox is the most common and widely upgradable, found in many m4 airsoft gun AEGs like the G&G Combat Machine CM16 Carbine and VFC MK18 MOD1. Proprietary gearboxes, such as the one in the ASG Scorpion EVO, offer advanced features like quick spring change or electronic control. Custom gearboxes can deliver unique performance or durability, as seen in the Knights Armament Stoner LMG. With this variety, you can select a gearbox that matches your needs for upgradeability or specialized features.
