You should probably post a pic. IIRC, it was a 1/8" pipe nipple under the box. Maybe you're looking at a 1/8" NPT pipe plug?

The "Magic Box" was two separate pieces of piping. The rear one was just an extension, and screwed into the normal regulator inlet. The gun's air line (from a CO2 tank or from HPA) then simply screwed into that. That's it, just an extension.

The front one was basically another extension, but "blind"- it was capped, just a 'blank' extension. This one screwed into a hole drilled into the side of the main firing chamber (or "dump" chamber.) What this did was add a bare few CC of volume to the dump chamber, so that each shot released a slightly larger volume of air.

That meant, of course, that you could turn the pressure down slightly, in order to run the same velocity.

In reality, it dropped the chamber pressure from somewhere around 400 psi to perhaps as low as 350 psi. And reduced your efficiency by around 10%.

The "box" part was just a milled cover that clamped over the two pieces of pipe- with a sticker saying "do not remove" over the screws, lest you let the genie out.

Interestingly enough, there was an opposite version available for a while. An early custom shop- something like Foxhunter, or Hyper-something? It's been a while- that made the inner chamber smaller. That bumped the chamber pressure UP, from around 400 to around 450 psi.

That actually increased efficiency, again by around 10%. On the other hand, it made the trigger pull stiffer.

Also, it let Smart Parts charge $100+ for 30 cents worth of plumbing fittings.
-This part, though, is 100% true.

To the OP; if you're having problems with the old fittings leaking, I'd be happy to have a look. I can even block off and fill in the chamber port, if you'd like.

Ok I've had a look and that hex socket is actually an allen key for a plug, it never occured to me to try that lol. I thought it was actually welded in but it came out pretty easy, so wrapped it with Teflon tape and put it back now just to try gassing it up

Just to make it agg I might put a gauge in there lol

Thanks for all the help

I thought that was what you were looking at - it is an expensive tool to bore a hex into the side of a Mag - and I could not think why anyone would do this.

It will probably be more agg than you expect. The rapid chamber pressures are very hard on gauges. and you will either have to buy a fairly high dollar gauge or it will be broken quickly. Either way, very agg.

See that was what I was thinking, I couldn't understand the logic behind it and it just never occured to me

Well as long as it hides the ugly cut out section of the body a bit and dosent leak I'll be happy just want to actually use it, can't believe I've had it lying around for about 4 years when all it needed was some teflon tape!

Does the plug fit flush? If so you can probably get a regular body on there...

1 replace body
2 ???
3 get chicks
