I've only owned the rifle for a couple of weeks and haven't shot more than 150 shots. I haven't cleaned the barrel yet.
One of the things that surprises me to learn here, on AGN, that many folks say not to clean air rifle barrels until or unless accuracy begins to falter. I'm accustomed to powder burners that I clean more often, not because accuracy has fallen off, but to prevent corrosion from the powder burning. Of course no powder to burn with these air rifles.
I did find out last night when installing the sling posts, that it is VERY easy to take this rifle apart; unscrew the air tank (slight air swoosh), remove two allen screws under the stock, and lift the action right out. Goes back just as easy.
