Poppet valve, blow forward bolt?

Has anyone ever made a poppet valve marker with a blow forward bolt not attached to the hammer phisicly? I dont know why or if any good could come from it. Just a thought.

The simplest way to illistrait what I mean, but Likely not the best way to do it, would be a tippmann valve, with hammer and all that on the back side, but an automag bolt on the front, so that when the valve goes off, the bolt moves forward, dumps, and resets, independent of the hammer/sear in the back.
A similar thing could work with a spider, so long as the hammer can be cocked without the bolt. The top tube would just have a gas actuated bolt.
I think it would make changing calibers on the same guy Easter, because you wouldn't need .68 cal bolt travel on a .50 cal marker.
And the connecting rod falls off on my procarbine, if I take the site off to put optics on it. But that is just me

Just thought I would ask because there is nothing new under the sun.

Deadlywind Aedes - never made it into production. Pressure controlled poppet, so no hammer. But could very easily have been set up on top of a blowback hammer based system.

That's fascinating to look at. So would the trigger be fairly hard to pull if that is what controls the poppet?

Most poppets are solenoid driven, so trigger just activated a microswitch.

Alternative to a microswitch (assuming that it implies an electronically controlled system) would be one using a pneumatic valve similar to the Fabco (iirc) valves used in Pneumags and similar systems. I don't remember any new news on the Aedes in the last several years but the basic concept has been well worked out on paper. The example .gif above does ignore ports for said valve control though

The Aedes used the MQ valve, so a balanced poppet controlled by a solenoid.

I remember someone on MCB saying that the prototype was a ball blender and that the concept of a poppit blow forward bolt was way too violent.
