Introduction

In GBB the magazine does most of the work so it is good to know how to work on it.

If you have taken down the magazine this far you can start screwing the tubes and caps. Either end of the tube will work. The o-ring can be a little crushed and still work effectively just make sure the the o-ring is evenly in position. The pliers technique used in the disassemble can also be used to screw the tubes back on to the rest of assemble.

With the tubes and caps in place now is a good time check for leaks. If your valves have been removed begin putting them into place. Make sure that threads are line up and do not apply too much for to the valves.

  • As mentioned in the disassemble using the proper valve removal tools is always best but with care you can use standard tools as shown.

  • Once everything in place you can gas up the magazine. I recommend using a green gas can that is not at full pressure to save on gas if it turns out that there still is a leak. If the lower pressure gas does not leak try filling the magazine with a full can of gas to see if it can handle the higher pressure.

  • If your trying find where a leak is coming from you can use the silicone spray on hole magazine and look for the bubbles.
