Ryohin Buhin Electric Gun Ver. 2 Compatible QD Reinforced Gearbox Set with 8mm Bearings, Microswitch, Rear Wiring, Silver Gearbox V2 Version 2

[Compatible Airsoft Guns] ■ Compatible with standard electric guns equipped with a Version 2 (Ver. 2) gearbox. [Installation Difficulty] ★★★☆☆ | Because this is an internal drivetrain part, knowledge of gear and motor positioning and disassembly/assembly of internal parts is required. Depending on the compatibility with the airsoft gun, modifications may also be necessary. [QD Quick Spring Change] Equipped with a quick-release mechanism that allows you to change the spring from the rear without disassembling the gearbox. This eliminates the need to worry about gear misalignment or remove multiple small screws when changing the spring! [Standard Microswitch] The trigger is equipped with a short-stroke microswitch. This eliminates the risk of switch burnout and improves trigger sharpness. [High-Efficiency Silicone Wiring] The motor connector and rear-wiring battery connector are pre-wired and made of high-efficiency silicone for excellent electrical conductivity. [Bearing] Compatible with 8mm bearings. (Bearings sold separately)
