i have read what is out there on this pistol and got one today for a song
would not cock in the listing and guessed that the trigger was to light and that was the case
but from my reading it seems has a 25mm ID tube and was wonder, the question
what has been use to replace the piston seal if needed
not torn down yet but just looking
i was thing maybe a leather seal conversion in 25mm from Vortek might work
input here or message me so we could talk on the subject
