I've had bits of this one sitting around for a while, figured it's about time to dust it off and get some work done.
The breakthrough was figuring out that I could use a Tommy Gun drum for the chunky part of the magazine. The rest was just shaping, filing, sanding, etc.
Parts used: PSR body, Tommy Gun drum, Dadao blade, JFLR barrel and undergrip point.
More smoothing and general stuff to be done. Then maybe paint.
