From the preview:
We are redesigning a couple of the German weapons. Originally we were going to have an underslung grenade launcher - but we weren't satisfied with the look and wanted to go with a two dedicated GL troopers in the Panzergrenadier Gruppe.
The GL is built on the G-54 framework but features a larger barrel (of course!), enhanced fixed sites for battlefields with heavy electronic jamming, and a big ole drum mag.
This is a perspective view in an STL viewer of the piece. We'll show off the revised SSW next time.
