Help with leaky MK23 mag.

[Gunslinger]

Ok, so I had TJ from Youngs looking for Mags for this damn gun ( TM MK23 NBB) and with no luck, I'm wondering is there any way I can fix it?

I cant find any screws or allen head bolts to remove/disassemble the mag, so I was wondering if any one could give me a heads up or insight into a repair I would assume to be simple.

Does it sound like it is leaking out of the base plate when you use propane?

The TM MK23 is designed to use only duster gas to comply with the Japanese fps limits. To my knowledge it is the only gas pistol to use a bleed valve. In the base of the mag there is a small spring with a plunger on it. When a gas more powerful than duster is used the plunger compresses the spring and lets the gas out. Chances are your mag isn't leaking, but rather functioning as designed.

TM decided to make removing the bleed valve annoying for obvious reasons. If you look at the base of the mag you will see three pins on one side, and only two pins on the other. The two pins you see on both sides are full length pins that can be pressed out. That third pin that is only on one side is a half length pin that needs to be drilled out. Once the half pin is drilled out, the full length ones can be knocked out and the base plate will come off.

Once the base plate is off you will see the bleed valve. You can either remove the valve and fill it with JB weld or something similar, or you can jam something in there to hold the valve closed. I had to do this to all three of my MK23 mags. When new they hold propane but after a while it begins to bleed out very quickly.

The last and easiest option, is to order mags made by Y&P. They cloned the MK23 and make mags without the bleed valve. While I can't comment on their quality, they are propane ready drop in replacements.

Deffinetly go for the Y&P mags brother. I sealed that mag up with tfe paste and that fixed it for a while, but if it's leaky now, you'll have a he'll of a time opening it up.
