The Shepherd Turpin Enfield, also known as the STEN is a family of British submachine guns chambered in 9×19mm which were used extensively by British and Commonwealth forces throughout World War II and the Korean War. Introduced in 1941 when Britain was facing invasion by Germany and severe equipment shortages the STEN was notable for costing as little as $11 to manufacture owing to its extremely simple design, making them effective insurgency weapons for resistance groups, and they continue to see usage to this day by irregular military forces. The airsoft STEN is almost entirely dominated by Northeast who have made multiple variants of the airsoft STEN such as the Northeast Airsoft Sten GBB MK II (Long Branch 1943 Version) and the Northeast Airsoft STEN GBB Airsoft Classic Rifle (MK2 / SOE, Welsilencer, Commando Grip).
