Warhammer 40K Bolter
Just something I have been messing around with the last few days. Made entirely from EVA foam (just like my M8 Assault rifles) Rather than inserting a metal skeleton in this one I just hacked up and modded a Nerf gun for the core and handle.
Day 3 Progress: Still a lot of detailing/paint to add but the base of the gun is now finished. Scope is removable. The emblems will be sculpted/cast and attached last.
