Here is the reference I will be using as a base.
First I did the lower gas tube.
the grip section was sandwiched together in 3 parts, so that the center section could contain a built in trigger guard.
I carved a slot out of the center part, and angled slots out of the outer parts to hold the pvc barrel.
Grip at that point. I'm rather proud of how well this section turned out.
The stock can be quickly installed or removed, via a small notch I built into the lower receiver before I put it all together.
Building up detail on the stock:
Test fitting the outer barrel, with the receiver and completed stock:
Progress on the receiver
Hndguard test fit+ outer barrel adjusted to lock into the forward receiver.
Beautiful, 'aint she? I definitely under-billed my client for this one.
