Assuming you've replaced the o-ring on the piston and it's in the correct place? Not on the end before the cap like some suggest?

Have you tried cleaning it

No. I have run out of C2R.... :lol:

Yes...

You didn't run out, the oompa loompa stole it!

Closest place to get a gallon?

My house! Yours is still, here!

actually I had it with me Saturday and forgot ;-)

O ring is installed to stop gasses going forward along the mag tube? Inside the housing attached to the barrel. As my descriptive English fails me...

Thought that had not landed? Was not hinting...

[M99]

You must pay more attention or more time at the range! Everyone else has had theirs

[Demonic69]

That's the one, apparently it can cause issues cycling if it's installed incorrectly.
If it's like the normal escort it goes on before the barrel and sits at the end of the bit that goes around the mag tube, if that makes any sense at all :-)

[Demonic69]

Just read your post again, sounds right to me

[ChrisB]

Anyone know what diameter the gas ports should be?

[ChrisB]

And the ports now have less swarf and are a bit bigger....
