GBB pistol mag. Carboard in the gas reservoir??
 

I opened up my GBB mag todday to try and fix a leak. and i foring that there was cardboard in the gas reservoir. Is this supposed to be there? I removed it. after staring blankly at it in a state of WTF. I have never heard of this before.

Cardboard isn't Leak proof, now we know that don't we?
seriously, that's the first time I see that!
what's the brand of the mag?

seen it many times before. some brands put cardboard inside the reservoir to help with gasification of the liquid propellant. think of it as acting like a wick. it draws up the liquid and provides a much larger surface area for the liquid propellant to "evaporate". if you find it in your mags, chances are it should be there.

I assume that mag is second hand, and someone shoved that in there.

I remember this.

This^ ....is not it!

Think about it. The cardboard occupies space inside the mag which diminishes the amount of space for both liquid and gas to occupy. This is ultimately going to decrease your maximum shots per fill.

Increased surface area to vaporize is dumb because liquid propane to a gas is almost instantaneous, for our purposes, as it doesn't want to remain a liquid. As you shoot, gas is released from the mag. As gas is released the internal pressure decreases which is condition required for liquid propane to vaporize.

I was wondering what the propane does to the carboard glue?

and hush... they must charge 12$ more for the CSM "cellulose stabilized mags"

Cheers

well, if you want to put it that way, liquid propane will eventually deteriorate the cardboard as will the silicone. if it's some new handy dandy special cardboard that is inert to liquid propane and silicone, I take it all back and say that it's a buffer to prevent the liquid propane from sloshing around too much. :rolleyes:

I'm gonna go ahead and say that it is 100% likely that the cardboard is part of the packaging for the gas reservoir, which was left behind when the mag was assembled in the factory.

It's a benign quality-control fail.

LOL...the only thing that I could determine from referencing that old thread was this:
1. Everyone has a wild ass guess to toss in
2. Proper spelling and usage of grammar was more prevalent :)

IMHO...it's probably factory junk that wasn't removed during assembly. I cannot see how it would do anything to improve gas flow or functioning.

The only thing that I could remotely think of was some sort of crappy attempt at laminar flow (which is more for fluids than gas anyways).

The only thing I seem to recall that was to be ADDED to a magazine body was a ball bearing from some Nine Ball high flow valves...and I wasn't even sure what that was supposed to do.

From what I heard, GHK intentionally put it in their M4 Magazine since it helps with the vapourization....Atleast that's what they said.
