Hey, so i was using my guntwo weeks ago and it worked just fine, but this time when i aired it up if didn't want to shoot properly. What happends is that then i pull the trigger, the gun doesn't fire at all and instead emits a low "tisk" sound instead of firing. One in about every 3 shots it fires properly. I opened the gun up and relubed the bolt and it still does it, thoughts?
Edit: i also did get the new bolt part from etha when the springs failed.
