Air Arms Tx200 Prosport Breach seals

[danf1234]

I am looking for some help from someone that has fitted a Weihrauch seal in to an air arms Prosport or tx200.
I understand you need to use shims. Can someone please tell me where to get this seems or send me some measurements

Shims?
No way, Jose’.
It is better to replace the seals with the compression chamber out of the rifle, though.
Just remove the old ones with a dental pick and insert the new ones.
Put everything back together and shoot away.

Oh…My bad. Weihrauch breech seal..

I wouldn’t do it..

I have not had trouble with PS breech seals. Is there an issue requiring alternative seals?
thanks, clueless in CA.

Air Rifle Headquarters has them. Best quality I’m sure.

I looked into this and never found a true answer. What I did do was use a buna 70 dura on the bottom and a buna 90 dura on top. It is holding up very well, I even picked up fps. #108 oring

Got them from Grainger $2 for 50

Yes sir he has green high temp seals!
I also leave my cocking arm unlatched when not in use so they stay relaxed!
