The AR-180 is the rifle Sean Applegarth had in his scabbard when he arrived at Knockside. It is an accurate, reliable, semi-automatic weapon developed, as the semi or full-auto AR18, by the Armalite company in the early 1960s to compete against the AR-15/M16 and AK-47 rifles for military contracts.
The AR18 was a favourite of the IRA and known by them as ‘The Widowmaker’.
