The second we got given guns I wanted to make one for myself, it comes with a 3dmg because I couldn't find a way to completely remove it due to it using the gunskin for a strip along the back. However you can use it without with a white cape to hide it so I am including a texture for the non 3dmg version as well as the normal one.
