AEG 2.5 (Variable) / AEG3 (Recoil) Cut-Off Gearbox Shell without Bearings, Right or Left Side

The legendary KWA 3GX gearbox is heavily reinforced and radiused to provide years of reliable use. The introduction of the 3GX gearbox brought AEGs to a whole new level of performance by introducing KWA’s Kinetic Feedback System, or KFS, which provides a realistic felt recoil. These gearbox shells work with the AEG3 RM4 and AEG2.5 VM4 (cut off) system.

You can select either the right (339), left(338) , or both sides of the gearbox (by adding one at a time) in the dropdown menu. Please note that these gearbox pieces do not come with the 9mm bearings, which can be purchased separately in our ProShop.
