Kang Doel shows a customized Cyma MP5 Jund that has undergone a full conversion from a Gel Blaster to an Automatic Electric Gun (AEG). This transition from a basic model to a 6mm BB-slinging machine includes a metal gear set and piston, ensuring the internals are as sturdy as the exterior. The build features a 3D-printed mounting rail for a Spike Red Dot sight, because apparently, aiming is easier when you aren't just guessing where the plastic pellets might land.
