A WW2 Nazi rifle for Fallout: New Vegas as part of the Historical Weapons contest.
You can find the rifle in Doc Mitchell's house in Goodsprings. It's inside his bedroom on top of the bed.

Model looks good, although for the First person view I would use a cylinder with more sides for the receiver tube since it's right up in the player's face and the side count is noticeable there.
I am not good at texturing myself but, one thing that strikes me is that your textures are really desaturated. Comparing your work to Millenia's you could really boost up your colour saturation for parts for better visual impact and distintiction between materials:
The tutorials I linked to in your Owen gun wip should be more helpful than I can, but I'd like to reiterate that there is a lot of contrast in your diffuse texture between base material and scratches that should instead be on the specular map.
And scratching should happen more sparsely, being on parts that are more likely to rub or get dented - like corners, parts that move, and parts that stick out, not everywhere.
Analyzing refs and the work of more experienced artists is a good place for self study and experimentation. Sorry I cannot be of more help, my texturing ability is very weak as well.
