250Z 250z degas screw non-functional???

[BBGunn]

After my latest slug testing (reg. adjustments) I attempted to degas the rifle to re-set the reg. back to my pellet tune. The degas screw did not function. It worked as expected on prior attempts. I opened the screw as far as a full turn open and no air flow at all???

I degassed via loosening the gauge and dry fire. Then pulled the optic so I could see down into the degas screw hole. Nothing obvious to see inside the degas port from the top looking down.

I assume the degas hole is plugged with something but I haven't had the rifle apart to understand how the degas port functions.

Can you guys that have had the rifle apart point me in the right direction please?

I'll ask in a less confusing way. If I pull the barrel/air tube assembly will I be able to see the degas port hole from the inside of the block? Is the degas hole drilled forward of the thimble?

Yes, the degas port should be forward (toward the muzzle) of the thimble.

Thanks kindly.

Thanks kindly.

My pleasure! Oddly enough, I have mine apart at the moment. If you need any pics, let me know.

They would be nice to see for future reference if it's not too much trouble.
