Is this designed to launch nets to down quad copters?

Been a rough ride but we are finally starting full production of this straight pneumatic. The ATF seems to be loosening their stance with the pneumatic less-lethal launchers since all the .68 caliber kinetic rounds for paintball guns are being allowed even though they are over .50 as well. Just uploaded a few videos in the other recent posts.

Good to see more of your fine work, last time I saw your work was a video with jamie hyneman. Are you yourself active on any other platforms?

Iknowmy3tables,

I am not really active elsewhere but will try and be everywhere once we are in production. I will also be able to share more details of the system then as well.

Thinking about getting onto some airgun and firearm related sites to preach the gospel. Any recommendations?

Good job! Nice to see you're still keeping us updated. I will be following. I know the positive pressure piston valve, but do you now have a custom valve for the trigger? I remember the fist ones used 3-way cartridge valve by one manufacturer I know, but they don't go to 1200psi I think.

We were using two different Clippard valves that were both rated to 300psi and one could handle 800psi but the other would damage the seat at those pressures and leak after being damaged. We are using both Humphrey valves and our own custom valves for the trigger now up to 1200psi for the custom. The Humphrey's are rated lower but handle 650psi consistently. We have added a snap action to the mechanical triggers to replicate firearm trigger feel and also have a version that uses the same valves but with a second pilot being a 650psi solenoid valve for electronic firing.
