Each round contains either the M718 or M718A1 (RAAM-L) mines, which have a self-destruct time over 48 hours; or the M741 or M741A1 (RAAM-S) mines, with a self-destruct time of approximately 4 hours. Both projectiles are used with the M577 or M577A1 Mechanical Time and Superquick (MTSQ) fuze, which triggers the ejection mechanism of the mines above enemy territory after a preset time.{{cite web |title=Army Ammunition Data Sheets for Land Mines |url=https://bulletpicker.com/pdf/TM%2043-0001-36,%20Land%20Mines.pdf#page=116 |publisher=US Army |access-date=15 October 2022 |archive-date=22 January 2023 |archive-url=https://web.archive.org/web/20230122031708/https://www.bulletpicker.com/pdf/TM%2043-0001-36,%20Land%20Mines.pdf#page=116 |url-status=live }}
