Here is how to get into the shot chamber on a mag. If you want to devolumize your mag you will need to know this.
Also, here is the source to buy the shot chamber oring(the red oring). Mcmaster-car only sells them in packs of 100 so the oring store sells them one at a time..

There is the Lathe method and the drill press method
The drill press method(I think Loguzzzzzz did a thread on this once)
Get it clamped firmly into the jaws
Get it turning and use a hacksaw blade and cut about a 1/16" deep. (See the lathe pics for a better depth and location pic) It should unscrew with little effort once you cut deep enough. It is up to you what you crank on the two with to loosen it, but I dont suggest pliers unless you have many layers of Etape on it.
The lathe method.
Here is where you cut. 1.6mm back from the face.
Cut until it comes apart with some but not much force, trying it regularly so you dont cut to deep.
Here is how to get into the X-valve. I used the tools that most people will have available. Take your time and go slow.
Here are the tools minus a bench vise.
Adjustable pliers, a strip of plether and a vice
Clamp like this. Clamp it snug but dont over do it. Also use E-tape on the area the pliers will bite.
Now here is the hard part. Get a firm grip and slowley unscrew it
making sure the pliers dont slip. Take your time and redo the tape if you are concerned about scratching the SS.
If you are lucky you will not destroy the red oring. Once you are done you need to clean the thread lock off both threaded areas and you will not need tools to get into it again. :shooting:
