what will it be used for? for third person or on-ground weapon, its perfectly fine, just detailed enough. for first-person, you could cram in more detail than that if you wanted.
Like andyCr sayd this is a perfect world(on the ground) model.
For first person a higherpoly model would be better.
Don't forget to make a clip, slide and those other things that move.
Anyway this is a good base model to work from.
There are no hidden polys so all i really need to do is texture but i still need to learn how. Now i know how to get the uv map and open it in photoshop but heres the tricky part...i dont know how to use photoshop.
