Concept i did for fun, trying to put a rugged holo sight, and scope into a compact, easy to maintain in the field rifle.
I was going for a more old school gun machined look, victorian/early 20th century, mixed with modern tech. That's where the alternate history context comes from.
Also, checkout the link at the end, and the Forgotten weapons channel. Really awesome inspiration for weird looking guns.
I'm not affiliated with it, it's just that i use it a lot for references.
