My first DoD gun.zip

This download looks like a lua file. You need to place it in your lua folder inside the Garry's Mod folder.

You should end up with a directory structure similar to below:

• steamapps
  • common
    • garrysmod
      • garrysmod
        • lua
          • autorun
            • READ ME!!.txt
            • lua/
              • weapons/
                • shared.lua

• READ ME!!.txt
• lua/
  • weapons/
    • shared.lua
