This started out as a cyber gun cqbr m4. It’s been fully rebuilt, shooting 390-400 fps with .2s wired to deans. Externals Classic army nemesis rail Magpul grip Unknown rail covers Chinese brand LPVO red/blue illumination Magpul eps stock Cyma pistol grip Internals Madbull 6.01 aluminum barrel (runs almost to the end of the barrel extension) Prowin clone HopUp unit Maple leaf bucking and nub Gearbox shell is stock 13:1 shs gears Maxx full cylinder Maxx aluminum piston head Maxx aluminum cylinder head Maxx aluminum nozzle Asg 30k motor Perun v2 hybrid mosfet trigger system I currently have the gun tuned to semi and binary mode. Other notes: Because of the perun mosfet I wasn’t able to install one of the receiver pins so I’ve covered the holes with the perun stickers. Doesn’t effect performance at all. The gun hasn’t seen much use as I haven’t really been airsofting in the past couple of years. I will provide any sort of videos per your request.
