The files for this model have been removed from this page, from now on the files can downloaded for free from www.MyMiniFactory.com. This page will be left for legacy purposes and I will still answer questions if posted.
Sorry for any inconvenience.
Straight from the Commonwealth is the Combat Rifle and Combat Shotgun. As both weapons use the same receiver,butt stock, and magazines I have made all parts for both weapons interchangeable. This allows you mix and match on any of the barrel types or mods I have created for the base parts. First print out the 27 base parts, then print out whatever combination of parts to complete the assembly.
I will add more mods when I get round to it but, like these mods, they will also be interchangeable.
