I've made some progress.
The magazines are more or less done. I've just got to add a few of the details on the bottom. I think the screw head stem might be a little tall for RotJ, but I'm not too worried at this point.
The end caps are done. I've made a start on the rear sights.
Forward sights. U-rails. Forward D-rings. I was making the D-rings out of Al rod, but unfortunately the last one broke as I bent it. I had to drill out a plastic rod to insert a paperclip and bend that. It has a slightly smaller diameter, but it works.
I've also started on making some handles.
Aside from sanding down the handles I've got to wait until I get more plasticard to continue.
