All this was made from two images, both supplied as background images if you download. I just searched in Google Images 'MW3 Screenshots' and stripped the gun from the image with the Scratch rubber tool in the Paint Editor. I then rubbbed out everything except the back of the scope and handle, moved them, enlarged it and used the Stamper tool to copy parts, flip them over and make it look good. Then I moved it to align with the mouse perfectly and that's it.
