This is a great project gun for any tech wanting to tinker with something different. This aeg uses a 7mm QD microswitch gearbox. Blowback mechanism has been removed  It comes with the following internals: FPS softair ARX160 oring air nozzle Retro Arms tappet (nozzle is glued to tappet) SHS cylinder head SHS cylinder Anti reversal latch SHS piston head Gate NANO ASR mosfet ( used to protect microswitch) Lambda 6.05 inner barrel with Begadi FLY5 bucking Needs gears, bushings, spring, spring guide, and motor to complete. Externally there are some scruffs but overall in good condition. The image was taken without the gearbox which is why there is no trigger. There are a few other modifications I did which I'll be happy to explain if you drop me a pm. I can also provide additional images as well.
