Greetings all; thusfar I've been kicking the idea of the titular gun around in my head for a few weeks now, and after looking into some resources have reached the following conclusions/requirements:
The structure would be based roughly on Boltsniper's Fast Action Rifle, with the mechanical fire group and piston assembly replaced by a programmable electronic trigger linked to a sprinkler solenoid valve at the very back of the barrel assembly. The front of the valve would be screwed into he rear of the barrel assembly.

The solenoid would be linked to a compressed-air tank either carried externally, or maybe integrated into the front of the lower receiver, the rear half of which would contain the trigger assembly.

There would need to be a way (chop it out of an existing gun?) for the magwell to accept standard N-strike mags, which presents the problem of how to seal the solenoid end and the barrel end around the top of the magazine for when the solenoid is fired.

A battery housing integrated into the side of the gun for the solenoid and the trigger.

The barrel would need to be able to be detached from the magwell/solenoid assembly.

Does it sound feasible? Is there any way to make the solenoid/magwell unit sealed for each dart? Is it possible to program the trigger to pop the valve at the exact amount of time to shove one dart out of an imperfectly sealed mag, based on tank psi? Or is this all just a PVC pipe dream?
