I have been working on this model so i can post it on the unity asset store(for free),inspired by the awp on devassets http://devassets.com/assets/modern-weapons/ .It still needs work ,this is an early look and considering the fact that it takes 10+ days for an asset to get approved and posted there it is going to take some time.I hope you like it!
Looks good.
Since you are looking to share it freely might I propose also uploading it to opengameart.org?
