Cleverly concealed one-shot rifle designed by Professor Parker and used by Maxwell Smart when in Mother's Family Pool Parlor, a KAOS front run by the Shark. Before Max goes to the Pool Hall, Parker assigns him, among other things, a pool stick that shoots out a large bullet when its bottom is hit. Max uses it to disable Stryker (Shark's assistant) and to (accidentally) destroy the ceiling of the CONTROL Rec Room. [Episode #18: "The Dead Spy Scrawls".]
