[azzbat2387]

hey so having had a few co2 guns i know that breech seal wear out anyhoo got my first crosman gun today a 2250 2nd hand so nipped up to my range to chrony 3.5 fpe with 14.4 grain pellet  but when firing noticed hell of a draft coming from the base of the breech so i stripped it down as wanted to polish and relube internals when i got to the breech to gas tube seal found a small brass fitting and lots of what looked like perished bits of o ring  so my question to the crossgods is were there rubber seals on it if so either where can i get more or should i just replace the whole lot for a ptfe seal

thanks in advance

It's a flat edged O-ring of sorts. More a slice off a tube really. Again, as Tatsumi mentioned; GMAC is best online but a good dedicated
gunstore will more than likely stock them. "Woody's of Wembley" sells them for example.

It's probably a better deal to order a seal set or at least a few lil' bits to save on postage.

It's the third one from left to right:

EDIT: Is the little gasket present? Only they're not brass so I guess you mean the valve port?
         If the former is missing then add that to your order!
