What is this? It's not the usual magic box
 
What is this? It's not the usual magic box. Some type of high volume pressure set up?:huh:

The Magical Cylinder?

The cylinder of ill repute?

I don't know but its clean... maybe an attempt to lower the pressure?

Looks like something to reduce shootdown during strings of shots while using co2. Interesting to say the least. Does it shoot well?

swe_crazy 11-10-2012 02:48 PM

I've actually never shot with it. It has been a wall hanger:o. Have too many Automag / Micromag projects. Will take it apart today.:)

It's too far back for a "Magic Box". It actually looks like it's accessing the air path out of the reg, but just before the on/off. So, a "Volumizer" type of thing, that stores extra post-regulated volume?

Doc.

I have taken it apart.:D

Click on the pictures and they get a little bigger:)

Yep. It stores extra air between the output of the reg and the input to the dump chamber.

I can theoretically see that as maybe improving shot-to-shot consistency a tad, since there's now a bigger "buffer" of regulated air to pull from the moment the on-off opens up again, but there's a big difference between theory and fact. :D

After all, the Magic Box itself was supposed to add range, consistency, accuracy, two inches of length and an inch or girth, all that sort of thing, when in fact it did pretty much zilch.

Might be worth an experiment though. Try it over the chrony and at a target range both with the 'volumizer' attached, and then again (with the same paint under the same conditions, etc.) with the thing removed and the hole plugged with pipe plug.

Record the chrony readings and whatnot, and do a proper comparison.

Doc.

That hole is after the on-off, since the teflon o-ring seals the dump chamber from the input. Not sure it would pull anything when the on-off opens up.
