Handcannon

for my Lone manga. started with 2d drawing completed in 3d so that i can use it in ps
idea is that its like anti armor cannon, as you can see on 3rd picture it has no magazine,
you have to turn-open stock, release shell, insert new one, close stock and use lever to tight fix it.
It also has no optical visor, but has a connection port for head set.
Stock has recoil compensation, and the bipod is retractable.
Look is inspired by makeshift weapons of the future.
I didnt invest too much time in rendering, just so that the design is clear, i don't care for the rest.
