Everybody talks about real firearms and stuff, but if there would come the worst case scenario where you would really need firearm but still you don't have any or can't find any. Here is something that somehow easy to make with right tools and little bit of skill.

Home-made Marble Shooting Air Gun



Description:
Air guns are normally small air powered rifles that shoot relatively small projectiles, primarily used for target practice. Usually, they are pumped up with an internal cylinder, activated by hinging the barrel towards the stock. My home made air guns experiments however take their lineage more from potato gun technology than target practice rifles.

The nice thing with an air gun like this of course is that it can be used to shoot all kinds of stuff. AA batteries, for example. Or Pens, or sticks of wood. Or filling the barrel with water.

Handmade Pistol


Description: Note that this is from the diary of the maker of this weapon.
few days ago I finished making a twenty two caliber pistol. This took me a long time, for a year and a half, thereby preventing me from working on some other projects I would have liked to carry out. Gun works well and I get as much accuracy out of it as I'd expect for an inexperienced pistol shot like me. It is equipped with improvised silencer which does not work as well as I hoped. At a guess it cuts noise down to maybe one third.
This weapon was remade with info how to make this with crude tools and some improvised materials in 2 weeks.

Automatic home-made weapons:
Here is some auto-self made weapons. With the right info and improvised materials making of the would take about 1-6weeks depending to the skill of the maker.


Comment: Small but effective this weapon has one con: Its not very reliable and jams easily. Easy to make though.


Comment: One-hand held burst-weapon. Somehow reliable but one con: easily overheated. If you have tools to mold metal or materials similar to the right ones making of this weapon can take very long time.


Comment: This heavy but effective weapon is pretty hard to make but if you can make it you will be rewarded with great accuracy, reliability and range.


Comment: Similar to the AK-47 as it uses 5.45mm bullets, it has same tech as AK but this one is quite more moditable as you can fit a silencer into it! During Z-Day this is somehow good thing because if you're spying a horde and get attacked from behind using this wouldn't alert the whole horde.

Air-Powered weapon:

Comment this is very simple air powered firearm. It has "Classified" tech inside that pipe and it can be used to shoot old batteries.

PS: If you see and self-made FIREARM that wasn't mentioned in here, put it here. I would be thankful.
And by the way comment please.

Here are thevery basic plans for a CO2 cartridge cannon/gun.

Go to your closest hardware store and buy several feet of copper/steel/durable plastic tube/pipe and one cap for the end.
find a store that sells CO2 cartridges (the small brass ones, usually found at bicycle stores and occasionally airsoft/paintball stores) and buy as many of those as you can (just make sure that they fit in the pipe that you bought).
Go home and put the cap for the pipe on one end of the pipe (where else?), cut a small notch (this should be the size of a nail or a bolt) in the end of the pipe that you put the cap on, make sure that the hole aligns up well with the little protrusion from the cartridge (the little part that is about a quarter of an inch across, it usually has a screw threading) when you put that in there.
after doing the above get a nail or bolt that will fit in the hole that you made, figure out some way of connecting the bolt/nail to the pipe (you don't want it to go flying into your face when you hit the cartridge with it).
Now have someone hold the barrel of the contraption while you hit the bolt/nail with a hammer, with the proper effect, the cartridge should go flying out of the front end of the barrel with enough force to puncture/shatter a zombie skull at close range (making it a lot easier to beat it in with a baseball bat or something) or have some stopping power at a bit longer range.
I will try to have some basic diagrams of this up soon so that you can get a bit better idea of what this really looks like.



Home made gun turret:
what? don't have a gun turret for your vehicle? Then take a sniper rifle,AK-47,etc. and duct tape or nail it to the roof or back of the vehicle.

THIS WEAPON IS UNTESTED AND DANGEROUS! DO NOT POINT AT HUMANS (UNLESS UNDEAD) ANIMALS OR ANYTHING OF VALUE. DO NOT BUILD THIS UNLESS YOU HAVE NO OTHER WEAPONS AT HAND.
