Intro: How to Build an Airsoft / Paintball Gun
This is a homemade airsoft Sniper rifle. I havent tested the accuracy yet. Its body is from a cheap steyr aug aeg but with the exception of the barrel and breach every other part of the system is of my own design. To fire it one must run the attached air compressor, pull back on the bolt, and pull the trigger. This takes aprox 4 sec. and will be optimized in the future.

Step 1: Gutting the Aeg
remove all parts from aeg and gearbox except for the gearbox enclosure, the breach, the bolt, and the barrel. Ill add pics later
Step 2: Build Airsystem
I used a small 200 psi aircompressor mounted to the bottom of the hand guard. that is connected via 1/4 high pressure tubing to a vacumme solenoid valve. The length of tube acts as an air tank. the solenoid valve is flipped backwards and the wires are run to a push button switch ive mounted on the trigger. the pushbutton switch is connected to a modified kodak disposable camera. This provides the 200 volts required to open the valve because im using 10 times the pressure its designed for.
Step 3: Attach Solenoid to Right Angle Connector
the right angle connector is attatched to rigid tube, i used a craft straw. The bolt is slipped over this and glued to the bolt carrying package in the gun. Ill add pics later
Step 4: Attach Charging Rod to Bolt Carrier
I used a piece of brass sheet metal which i mounted on the bolt carrier with screws. the charging handle comes up through the left bullet ejection port on the aug.
Step 5: Final Prep
Now u simply attach a powersupply with a switch to the aircompressor, load bbs into the clip. And start shooting. For a powersupply i always use the "Militia Man Power Pack" from WillCorp. (check it out in the products atWillCorp
Its the only powerpack that can give you enough juice to run the aircompressor. and fire a cheap aeg at over 20 rounds per sec.
