Air Arms AA S510 AIR LEAK

I do have a hone, but the cylinder should be linished in the process before assembly.
Two HW100, Two RTI P3, One Daystate………..this is the only system with two vent holes in the HPA cylinder that I know of.

Question:
The gauge on this rifle appears to be connected to the plennum, down stream from the Regulator.
If this is correct, why does it read cylinder pressure?

The two hole thing is to replace the old way AA designed the fail safe feature. Put too much air in the old tubes and the tube's end would flare out an release the pressure. You had to replace the tube after that...

The new system just kills an oring.

There is a passage that allows cylinder air to bypass the reg to reach the gauge.

Australian warranty states "I am entitled to a replacement rifle".

well, all sorted now, on inspection found regulator seal to have been subjected to smearing through possible air friction/heat combo.
purchased new reg and dropped in, all good and working, not sure if its worth repairing the old one as a spare or not.

Yeah, OK Waze will be the old regulator. You never know you might need it and it’s always nice to have it. You’ll learn how to replace those tiny little seals. Yes, my two cents.

Waiting to see if the parts get sent.

so BSJ,
The cylinder is made to a maximum standard, as opposed to a minimum. It has been enabled for reduced weight and made the engineering slightly more complex.
Will they eventually go carbon fibre and simplify the whole process? I'm no design engineer, but carbon wrapping is increasing in popularity for HPA.
If you know what the regulator is set at you only need to know remaining cylinder pressure, so the gauge could be located in front of the reg, and change the current filling apparatus to male foster in the same housing. RTI Arms have the male foster, externally adjustable reg, cylinder and reg pressure gauges in the one housing; if they can do it in Slovakia...... (One gauge would be sufficient for fixed reg for most people, my thoughts.) Weihrauch: adjustable reg, one gauge, power adjustable also with hammer.
My two cents worth.

Eh?

AA has been using this basic design for 30+ years. With slight improvements here and there over that time. I don't see them ever implementing any of those features in this line and still calling it a S5 or S whatever might be next.

Recently rebranding and rebadgeing lower end Asia made guns is evidence they are struggling to remain viable. If your gun's problem is indicative of systemic QC problems, I foresee even more negative signs...

Not good for the air rifling community.
After springers, I got the HW100s nine years ago.
This is my first AA, and only know that a friend regretted selling one; meaning accurate and well made.
This tiny burr destroying an Oring in assembly I hope is a One-off, and not a batch issue. If they don't supply the parts they are giving a second rifle away. Not good for business

Just been informed about a second rifle with the same issue in Australia.
