Sheridan Jackel Double action. Has the ASA adapteron the bottom so you're using a tank instead of 12 grams. Is break breech to clean the barrel out. Barrel is plastic. In great shape. No damage anywhere. Aired it up and tested and it seemed to cycle fine but I did not shoot paint through it so I don't know how it was chronographing. Probably needs adjusting. Double actions always shoot low in my experience (without modifications). Serial is 000715721.
