Hey guys, I recently got a mag with a what I thought was a lv 7. Today I was looking through some extra parts and found an extra lv 10 assembly so I figured I'd just pop it on and when I went to unscrew the tip of the power tube, and the whole power tube unscrewed as well, I was just curious as to what kind of valve this is, as I have not seen this before.
Thanks, and here are some pics of said valve.
