Hello and thank you for looking at my post, I have an etek 10 that Ive owned for about 1 year. Last nite I installed a new hush bolt into the gun, when I went to test fire it after I installed the bolt the ball just rolled out of the barrel. It sounds like the gun is cycling and trying to fire but it does not. I made sure that I had the bolt position correct, I even reinstalled the old bolt and it does the same thing. Previous to this its been about a week since Ive fired it but it was working good up until this point. The only thing that I have noticed is that it seems like the first shot after it sat for awhile was always very underpowered. I would appreciated any help!
