Buying O rings off ebay

HI! Since Rachel @ AF is concerned that Indian laws dont allow import of Orings to INDIA! – (The same laws that allow me to import the rifle into Into INDIA duty free without any import licence etc.. just by presenting my club membership cards to the customs allow import of parts too 😉 ) and I should contact their dealer in UK gunpower for the same 😯 🙄

Strangest thing is that when we import firearms we get firing pins , springs, ejectors, extractors , spare bolts -virtually anything we want from the manufacturers /resellers and here we have a company and resellers who dont want to sell any spares even with the export order!
and that too for a PCP!

anyways I read some members posts that they had bought the orings from ebay. Just did a search and the prices as well as shipping costs seem very resonable. Can you advice on any particular seller or brand which is good and which material type in 90 duro should I get ?
thanks
