What about putting two ions side by side? I know it'd be somewhat wider than with a custom valve, but it could make the build significantly easier. Plus if you did the over under version, width wouldn't matter as much, since then it would be a matter of how tall you'd want it to be.

or used 2 ion valves? opps too slow, :lol:

Over/under with a two stage trigger or a separate trigger for each barrel would be absolutely awesome... Olympia anyone?

the Back section is the valve. The last posted picture shows a 2d of the inside. It would be multiple parts that would assemble in to one.

Setting up a duel valve option would probably be easier to build. Two stage trigger shouldn't be that hard.

Using an Ion is not an option. Would only bring the cost up If anything.

Also am curious.

Looks like the composite gun built by John Malkovitch on the 1993 movie In The Line of Fire:

I'm curious to see the end result.

About it's firing mechanism, have you thought of a Nelson valve with two internal chambers, two power tubes and two hammers being pushed forward against a spring and being held on the front by a couple of sears taht when released, would allow the hammers to go back against the power tubes's bases? That would make it more "manual" but would be exactly like the movie's gun. LOL At least it would be pretty easy to maintain and service.

My thoughts were fewer moving parts the better. Can always do duel spool's. Might be a tad longer.

But would be better then using a ion. Ions would need a new spool and a seat for it work as well as something at the rear for an air port. So why bother with making some work with what your building if its not going to be plug and play. Better off making what you need.

Cost of building one still working on that as I don't have all the details I need on the hinge setup. I have the basic idea of it . Just haven't been able to get the details done on paper yet.

Well did the math on making these. If your really interested in seeing a few made and Want one and are willing to invest or pre order one (how ever you want to see it)
I would say i would need at least 2 people possibly 3. Pm me if your sure you would want. don''t contact me just to see how much. wasting my time is also wasting yours..

But anyways. I figured i could build these for around $300 to $400 each (not invested or preorder price) that would include the materiel and my time for a build. But would not include stock or frame as well as reg. Those would be extra since they won't be built by me. I may make a frame for them but un certain on how go with that at the moment

If you decide to contact me. For the quote of whats needed to make this happen. I will divide it by 2 or 3. Any more and would not be able to give you one for your time, money, and patients invested. So for your contribution you will be receiving one.

Think divide by 3 is the best choice

This is where I get hung up (without a mill). It reminds me of a pneumag. You get all caught up in the valves and actuators, but it's finding a good spot for the LPR and the hoses that makes it look right. A good hinge and breech will be important on a shotgun style marker.
