Abstract
A non-spinning 40 mm ammunition round for firing in an M320 grenade launcher. The round includes a cylindrical shaped gun sleeve cartridge case, which covers the standard rifling inside the M320, and thus presents a smooth bore surface to the fired ammunition. Because the ammunition is not launched in a spinning mode, it may now comprise those guidance and camera components as may be desired which components would not have been possible to employ on a round that is spinning.
