How to build a pneumatic gun

Today we will tell you how to make a real air gun with your own hands using improvised tools.



So, let's begin. To get started, you will need the following materials: a metal tube with an inner diameter of 4.5 millimeters (you can use a tube from the old radiator of the refrigerator or cheaply buy at the nearest flea market), which will serve as the barrel of the future gun, a piece of wood, a screw, a piece of rubber (you can cut a small piece from the old tire chamber), as well as two fittings that cost about a dollar (you can also use the fittings from the old tire chamber of a car or bicycle), bullets from an air rifle, which will shoot the future weaponsas well as the usual plastic half-liter bottle.


At the very beginning of the manufacturing process, it is necessary to make a hole in the upper part of the bar with a depth of 5-6 centimeters. This is the first hole.

When it is ready, you still need to do it in the side to the middle of the bar. Care should be taken to ensure that the diameter of the drill and tube are the same.

In the end, you need to make another hole, this time through the diameter of the screw.

The holes are ready, it's time to figure out where to be inserted. So, in the first hole you need to insert the barrel of the future gun, in the second - the trigger, and in the third - the fitting, as well as a bottle of compressed air. Since the last hole is drilled along the diameter of the screw, it needs to be slightly expanded to the middle so that the fitting enters it.

The next step is to install both fittings on the top and bottom of the plastic bottle. Drill the holes required to install the fittings using a drill. To fix the fittings, you can use glue.

After all that has been done, you can start assembling the gun itself.

First you need to stick the barrel.

After that, screw the fitting to half the bar, that is, to the end of the thread of the fitting itself and glue the upper hole.

The last thing will be the manufacture and installation of the trigger or trigger.To do this, cut a rubber strip and screw in its middle screw (not until the end). Next, gum with a screw must be sealed in the remaining hole so that air does not leak through it.

The gun is ready. It remains only to insert a bullet into the barrel, push it slightly, aim and pull the trigger.

ATTENTION!!! Do not aim at people; an air rifle can cause serious damage to health.
