Well the question pretty well reveals I don't know jack about the air rifle world apart from my break barrel Gamo and the daisy lever (not even a red ryder). Though the daisy has served me for about 40years until recently as I left it in a moist environment and it rusted the barrel till BBs would no longer pass through. It was my carpenter bee killer. Anyway apart from not leaving my new Kratos out in the shop what maintenance does it need. It resides in a safe room with a dehumidifier along with the powder burners. Owners manual says silicone oil on the barrel oring every 500rds or 3 months. Where's that at? Maybe I'm just a dummy. What else should I do if anything? Thanks.
