I always convert them unless it's something special*, Donald.
The trick with them is to make sure the nylon head and cone are a close match to the cylinder end and the O ring is a nice sliding fit in the cylinder.
I check that the nylon head and cone are a good match to the cylinder end by putting Tipex on the front of the piston and rotating it against the end of the cylinder --- if the Tipex is wiped off all faces it's good to go.
With an O ring piston head fitted you can normally get away with less Spring for the same power output as you get from a leather seal --- the conversion is fully reversible as well so you're not irreversibly altering the gun.
All the best Mick
* - I serviced an Airsporter as a favour for an old boy and it turned out that it was a transitional MK1/MK2 model so I left that one as it came from the factory.
Personally as an Airsporter collector, I think it is £50 over priced for a dealer, but considering which model it is, MK2 concealed lever S (probably the prettiest after a late S carbine)(I dont go mad for Stutzens for some reason).... I dont think its as far over the top as some are saying.
It is in a quite nicely figured walnut stock which is pretty unusual for an S.
Privately I would be happy to pay £275 for that and maybe £325 in a dealers if I really wanted it. Pickering is a lovely shop and friendly and I am sure if you walked in with cash a deal could be done, but they will price it with a PX in ind so maybe thats not an outright sale price?
The best shooting models for accurate shooting are late mk2 with dovetails and a late rotary breech model.
I have a soft spot for 1980's S models and 1950's Mk1's, especially clubs, but I struggle with open sights now.
If you need an accurate vermin tool buy a TX200 or Pro sport.

There is an 'S' listed in sales that sounds interesting if you fancy one: https://www.airgunbbs.com/showthread...A-Airsporter-s
People who have been there focus on the fundamentals. People who sit at keyboards all day focus on the trivial and inane.
Thanks Mick.. I'll need to have a look... I've not tinkered for years now, having sold the lathe and burnt down the shed, also powder burners are my tipple now. I've got a cadet major here and the airsporter that I'd like to get into nice condition fir the kids. Start them off on a cadet and cadet major, then move them on to the mk2 airsporters.

Hi
I have a mk1 'S', Have to say, The mk2 'S' and mk7 Airsporter stocks were prettier with their rounded forends!
First one on the left..
The old mk1 Airsporter with tapered forged barrel is my absolute fave of all the 'Sporters though
First three of these are mk1, Second three are mk2..
And here's a 'scoped mk1'
Those are the sellers pics, Can't recall for sure but I think I paid £50 or £60 for it posted with the scope too some years ago, The Blacksmith style scope rail was removed immediately and the scope went on to a rifle more apt for it!!

The link does not open for me.
As the owner of 4 Airsporters including a MK2 S I suggest that you
"Try before you buy"
They are nice guns but very much of their era.
The "S" versions compared to the Non S are like the Ford Capri vs. Cortina i.e. virtually the same mechanical bits in a pretty frock / bodywork / stock.
The "Mark" systems are also independent of each other, check the dates by Serial Number,
I love mine, but my Weihrauchs are far superior in terms of handling and build quality.
Nothing wrong with either option, purely a matter of taste.
Better to find out before you fork out hundreds of pounds,
