Firearm Pixel Art

I've decided to embark on an adventure to make a bunch of pixel-y pictures of guns. I have created a few so far, and eventually I will release the map file so people can add to my pixel art firearm gallery.
If you wish to see the list of firearms I have created in my world (each one has an image on this post), see Additional Notes.

Want me to make a certain gun and add it to the gallery?
Simply leave a comment specifying which gun I should add. I'll try my best to replicate it. Please be specific (e.g. say "M2 Browning", not "Browning machine gun", as there are several Browning machine guns).
If I decide to add your suggested weapon to the gallery, I will give you credit in the caption of the image, in the form of:
Gun (suggested by Name)
as well as adding your name to the "Additional Credit" section. Unless otherwise stated, I will post your name as your PlanetMinecraft.net username. If you wish, you may note that you would rather remain anonymous.

Please ignore the Progress Bar, as this is an open-ended and possibly endless project.
