A while back I started a thread about one of my Daystate Tactical Airwolf's stock going sticky. While I don't shoot that much anymore, I still 'fondle and caress ' my beloved collection. It was while I was doing this that I thought why only one of the Airwolf's stock had gone that way and the other is still good, even though both are stored together with other rifles ? Any thoughts, apart from Daystate didn't do their homework ?
