So, there are 4 different ways you can degas and the one I used in that video was the same one Huben themselves demonstrated in a previous YouTube showing how to replace the open valve seal. This method is the quickest, I wanted the video to be short, and this method isn’t possible with a jammed projectile or lower than needed air pressure to “fire”. My second choice would be the brass flat head screw under the loading gate. My third choice would be the silver set screw under the air probe fill on the GK1 where the check valve is located. And my last or never choice would be the torx screw at the top of the receiver. Why - because there is no o-ring on this screw and after loosened you can get a slow leak. In 2 instances I have repaired the owner tried to “fix” the slow leak by over tightening the torx screw and in 1 instance sheared it off and in the second instance stripped the threads in the top receiver block. Both were costly repairs.
