Ydna's MECH Ion!

You wouldn't. I was just stating it is possible to do a Pneumatic version of nearly every electronic marker made.

It's not as easy as it sounds to do right. Keep in mind, with any Sheridan based design, there are difficulties that would have to be overcome. The most important of these is this:
Consider how upping the dwell of a Timmy or Viking causes the velocity to increase typically, yes?

Now consider the dwell of your gun is now, in most of these potential mechanical conversions... determined by the amount of time you pull the trigger back. This could lead to anything from sporadic chrono readings to the fact if you hold the trigger back you're keeping the valve open and wasting a lot of air. (Actually, even in the parts list for the conversion Ydna indicates that the bolt/bolt stop was modified to seal off the dump chamber...)

That is the one problems with doing mechanical versions of those guns and is exactly why it can only be produced with electronics.

It would be cool to rig up a mechanical Timmy, but it wouldn't be practical or safe and it would require alot of work.
