RTI Rti mora hammer adjustment

Hi guys wondering if anyone can help me I was adjusting the hammer on the back of my rifle as I turned the Allen key to adjust a load of air started coming out so tried to turn it back but all the air released out.. is this a o ring that has broken?? And a simple fix or is it more ? Appreciate any help 🙏

Hello, it is the Last Mora with the pneumatic hammer or the first with spring ?
 
I'm.not sure. I think it's pneumatic. I've just took it out no spring on it and a oring has broke so guess it was the oring.. ?
For check if it's the last one, you have holes in the large black a nut located between the barrel and the Mora block, or again, below the adjustment wheel is a 6-sided nut and not a wheel that is turned.

Hello you have the update mora so no need to set the spring hammer, no more spring it's a pneumatic system with automatic setup with the air pressure.
If you have trouble with power, check the barrel if it's turn at the right position.
Before, with the first one you had to turn the valve, but this is not the case on the new models.

You simply have to turn the barrel so that the transfer port openings are facing each other. It's even simpler than before.
