I made this rifle as a response on a blend request.
I did not know your intentions for the model so I left all the pieces separate for animation benefits.
I have added a few basic materials to the rifle for character purposes. These are using nodes.
I have set it up in cycles but it is easily transferable to other rendering methods.
It is slightly less than 44,000 vertices. Which is around mid poly for me.
Enjoy this model. And update me on your work with this model. :)
Sucks that your other blends were deleted :/
