Ok, after a lot of head scratching, frustration, and finally thanks to some pics from Kurt, I've got what is left of my airsoft AK-74 installed into my ZF1.
I ended up stripping it down past the point of usability, removing pretty much anything that wouldn't be seen (or fit), including the motor in the grip, leaving just the receiver to house the clip and the trigger.
Luckily with all of this removed, the grip out of the studio mold fit perfectly on the receiver, and fit nicely into the frame area. I did have to cut out the lower cross member that goes under the big barrel in order to get the clip to fit, but it still works fine.
Using Kurts recommendations to add some pointing points, I put two small bolts into the front of the receiver and one longer one into the back end to hold the weight.
Now that it's all mounted it has an amazing feel to it. Everything seems to line up perfectly, the trigger dry fires and the clip is removable. Exactly what I wanted it to do.
I'm not sure this was worth the $150 for the parts, and the utter destruction of a perfectly good airsoft gun, but ultimately it looks and feels just like I wanted it to.
Oh....if anyone has a need for a airsoft battery, charger or any random parts, let me know.
And yes....the clip will get painted.
