I pulled my old Feinwerkbau 124 out today after too many years and the pellet would not clear the breech. I applied some silicone oil and moved the piston several times before firing it but no go. I think it needs a new piston seal.
Can anyone give any ideas where to send it. This is one I purchased from the old Air RIfle Headquarters, I think up in Virginia or West Virginia back in the mid 70's
