SPAS Inspired Project... Semi AND Pump?

I hhave been researching the SPAS due to its unique semi AND pump dual action operation, and it has me wondering.. Is this possible to replicate in a paintball gun? Is it possible to have a paintgun that is semi-automatic AND pump action, at the SAME TIME?

If my understanding is correct, the pump action of the SPAS is used for low-gas less-lethal rounds... So would it be possible to set up a marker almost like an autococker for the "semi" mode, with an on/off exhaust valve for the "pump"?

Make an Autococker that you can connect/disconnect the trigger and pump to the 3/4 way. That would be a semi to pneumatic assist conversion, and could be accomplished with something as simple as a couple of powerful magnets.

Sorry Ty, I dont have ANY experience with autococker pneumatics, so that sounds like a lot of garble to me. ha

*Now researching autococker operation as to become a valid part of discussion*

This is something I was hoping to be able to do on the fly, in a "play" situation if need be.

My apologies for the double-post, but I finnally think I understand the termanology enough to understand how to explain my idea...

Would it be possible to mount an on/off controlled release valve in front of the ram to prevent recocking of the marker when it [the release valve] is opened?

That way when the release valve is open, the marker could be manually pumped, but when the release valve is closed the marker would operate as normal?

I apologize for the awful spelling and vauge description.

if you mounted the lpr on an on/off ball fitting you could have an on the fly convertable just no pump kit.

Any ideas for a disconnect-able pump kit?

Use a double shaft ram, and design the pump handle to disengage the shaft and turn on the LPR for semi operation, and when you engage the puimp to the shaft, turn off the LPR to disable semi operation, and make the marker into a pump.

I hope that makes sense... Too many hours awake makes in coherent sometimes
