BSA R10 leaking air

[MRGbb]

Have just filled R10 today (its been unused couple of months but air was about 11o-120 bar, filled it today just over 200 and pull bolt bag and air pours out, with loading bolt closed air escapes out of muzzle.. Its a peppercorn bull barrel one approx 8months old. Any ideas as to why it should suddenly leak? takes about 3 mins to empty buddy bottle from 200bar

Hi check out xtxair video shows you how to fix this you need to clean the firing valve.

Well if it's only 8 months old it's still under warranty and unless the fault is trivial i.e something that can be replaced easily, which I doubt, get the dealer from whom you bought it from to send it back to BSA unless he's authorised himself to carry out warranty work.I wouldn't tinker with it because in doing so you invalidate the warranty and what happens if you can't fix it after trying and it has to go back,you have to pay if the warranty is void.
