hi i need help from the expert,
my ciener will stop after 3 to 4 rounds of full auto fire i am using a high velocity ammo. when i check the bolt i can see that the hammer is down and there is no sign of the firing pin hitting the live ammo inside the chamber.

what can i do?

Do you have the anti-bounce weight installed?

Check you firing pin.

It may be broken.

I was having a similar problem with my 22 upper. It ran great in semi-auto but in full-auto it wouldn't work most of the time. I had the ball detent mod done and it still didn't fix the problem. I had to install a lakeside recoil spring and the anti-bounce weight. I thought I could use just the ball detent mod and get rid of the anti-bounce weight but I was wrong. Still have to use both to make the upper work properly.

The upper works great now. Badazzar15 helped me with mine and I am sure he and others on here will be able to get yours running like a champ.
