any idea how this dart gun works?www.ayamedesign.com/images/portfolio-da ... 3d tool.

Looks like it is basically a sear released blow forward bolt that just blows forward the entire barrel instead of a bolt...if that makes any sense.

On the 3d image you can click on the eyeball next to each part on that list on the right to hide the part and see what is underneath it. You can also right click and turn transparency on to view the insides of a part. The spring is missing from that 3d image, it would be between the front ring on the barrel and the case.

CO2 fills a little chamber inside the part labeled valve body and the very rear of the barrel assembly seals off the outlet of that chamber and is held in place by the sear connected to the solenoid. When the solenoid is triggered it releases the sear and the barrel is pushed forward like a blow forward bolt and CO2 flows into the holes on the back of the barrel. Since the pressure in the chamber then drops the spring pushes the bolt back to where the sear catches it and the gun is ready to load another dart and to be fired again.

Here is the link for anyone else who want so look at it.
