I have 2 spare from memory, but would need to check. If you can't get one let me know. 

Multiple seal options if you want to buy online from offshore:

Turning all the bits up next week so will show photos when it’s about to go back together.
Just got O’rings coming down from Wellywood so will see how it goes.
Keep you posted. Parts less than $20 just an hour or two machining.
Using existing spring, would have liked original but will see how it shoots
The spring guide in it now is very loose so next one should improve the buzz.

I turned up a top hat and guide for an HW80 out of delrin, and it was like it had snowed around the lathe with the amount you take off.

You don’t get anything thing out if you don’t put the work in.

Just got finished and Prosport is much better no spring twang as with the old loose spring guide
Turned a nice tight one up in Nylatron as are the piston extension and top hat, a slight radius was required on
Seal undercut to allow fitting of the extension also needed 4 slots to allow expanding to fit a good tap with
My tapometer so this is a nice tight fit.
A bit stringy to turn but pleased with results and new seals now a lot cheaper and easy to change.
New breech o’rings aswell. The spring isn’t standard so would like to get one as this one seems a bit strong but
Will see how it goes 31coils. Hello I will get some photos on.
Shimmed side play in trigger now much better
Piston extension 17.5mm
Copied what a UK guy did but used existing undercut and didn’t need to use securing screws.
