Have a chance to buy a Air Arms Camargue in .177. It just about as new condition. Was with the guy today and put a pellet through it. Everything seems fine. It did seem to have more kick than I’m used to and probably a little more pop than my Prewar rifles. I assume that these have a synthetic piston seal given these are a 1980’s rifle. Anyone know how these hold up with age. I know some synthetic seals can degrade over time to mush? Are they worth collecting they have a amazing bluing and walnut stock.
