Link doesnt seem to work, also is this for free?

Good model, good topology, clean uv map, good textures.

Your model is over priced, I know you spend a lot of time on it but you are competing on the market.

Think about your model from a shopper's perspective, some one who doesn't even know the basics of 3D modeling; to them things like sub-D doesn't matter.

Most indies spend no more than $50 at a time, if it was me I would grab a cheaper m37, shotgun shells and a first-aid kit.

I recommend you price it at $15.
