YouTube- GHK PDW GBB Airsoft
Machined receiver and looks to use WA M4 mag, so not quite 100% accurate, but better than having to buy special mag for one gun...although WA mags will be expensive....
Being GHK though, I guess it'll work alright(as shown with the vid) with the GHK mag...which is the cheapest non-clone out there...
This has my attention....
