Problem with brand-new rifle.
I bought my brother a Storm a few weeks ago and it was working fine. This afternoon it was suddenly losing MV, even with a filled tank (firing it lower didn’t make a difference).
Checked the valve assembly in the bottle, no probs there. Stripped the rifle down, it appears one of the breech-block o-ring grooves has been cut too deep, allowing the o-ring to stretch over time and it no longer grips the barrel at all. The other o-ring binds nicely. Also the edges of the flawed groove are scuffed, indicating the barrel has been bearing on it instead of on the o-ring.
Any easy solution, or is it a return jobby? A custom replacement breech might be the best solution, not being impressed with AF’s machining as he is right now.
Any advice or help would be appreciated, he’s pretty teed-off right now (crying like a babby 😆 ).

The problem with the putty and machining fix is he’s in Lincolnshire and I’m in Sussex, 300 miles apart.
Thanks for the reminder on the other chap, I’ve posted and PM’d him. 🙂
See it these are still available. But you could fix it with EPOXY PUTTY in just a few minutes.
If the groove is cut to deep then fill it with epoxy putty and remachine the groove.
I thought of winging it with a bit of epoxy to fill the groove in a bit, but not to machine it.
Do you do custom breeches by any chance? He’s e-mailed Tony, but Tony seems a bit tardy replying (I waited four days for a reply and ended up going with Leupy before Tony had replied). Thing is I’m supposed to be going up for a shoot with him on the 16th of august and now he has a non-functional rifle, so a replacement is needed pretty PDQ.
Replace oring with 90 duro ones and see how the fit is.

Use a bigger oring 😀
