Does anyone know the size of Kral Puncher series breech/barrel o'ring in .22?

Scott For what its worth Bagnall & Kirkwood sells them , they are also on Amazon (same ones) but I'm sure you know that . I exhausted all my efforts trying to find a complete list of sizes for a complete rebuild . PA tech said they didn't know but a lady from Air Venturi got on the phone & had them put together a complete package for me ( cost was around 20.00 to 22.00 bucks .I believe her name was Stacie . Going to send the whole kit to the o-ring store a young man there said he would measure them & set me up . when I get them back I'll post the sizes on the forum . They happen to be a big secret for some reason lol Darell
