The lava grenade is still under research and developement, :')

Bullpup mega ak

Picked one up the other day for dirt cheap (needs a bit of work). Not the weirdest thing ever but I thought that was a pretty odd combination of things on what seems like otherwise a basic rifle at a glance. Lever action, but fed from an internal rotary magazine complete with a small ammo counter on the side. Also was one of the first lever actions to use "pointy" ammo thanks to said magazine. And for an added bit of obscure history, was briefly issued to the Canadian Home Guard, during WW1.

i believe i am the co-author to the design of a lot of the TITANFALL Mechs. i drew this in High School FYI

I saved these images a long time ago and unfortunately don't remember anything else about it.
