Is there resources for this ?

I'm not sure what you're asking. Are you looking for the project files? Those are under the downloads tab. 

i have downloaded them but does not have Assault Rifle. is there any for that ??

Ah yes there is, looks like they didn't transfer over properly. I re-uploaded them, they are a separate set of project files specifically for the assault rifle chapter. 

Thank you :) awesome work by the way.
