ICS m4 split gearbox design. Has two functional upper and an upper shell. Two lower gearbox. One functional and the other is a spring and the little black piece in front of the trigger needs replaced if you want the safety to wrk. I have some wire thrown in as well as a trigger and trigger unit thrown in on the second gearbox. Gun could be re shimmed as I don't have any. And the motor height could be played with a little bit. Has noveske rail and 6.03 tbb as well as legit moe handguard and stock brass barrel. Wired to deans and has a deans plug on the wires included for the second gearbox. M Not necessarily looking for trades but feel free to offer. If you have a pdrc I will love you forever. And I can maybe include a KWA mk23 with legit Safariland holster(also for sale)
