  • 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.
