My last craft project which I can't finish due to lack of space and time. (Therefore defective sale)
There is a red dot from VictoOptics, 4Midcap, Highcap and adapter (without which you can use normal M4 magazines).
Internal is another Black Python 2 from Madbull and a Cyma Mosfet + made hopup. + Trigger and selector fit together.
Just make an offer :) - Zynos
The ABU981 Tag is from Airsoftbörse where i also use these Pictures
