The Accuracy International AWM (Arctic Warfare Magnum or AI-Arctic Warfare Magnum) is a bolt-action sniper rifle manufactured by Accuracy International designed for magnum rifle cartridges. The Accuracy International AWM is also unofficially known as the AWSM (Arctic Warfare Super Magnum), which typically denotes AWM rifles chambered in .338 Lapua Magnum.

On 9 September 2012, Accuracy International announced that the .338 Lapus Magnum AWM rifle was phased out and replaced by the Accuracy International AXMC sniper rifle.[1] The bolt action of the AXMC was designed to be significantly stronger and more capable of handling higher chamber pressures and temperatures and thus higher bolt thrust safely compared to the AWM and hence is longer and wider. The AXMC magazine was also appropriately enlarged to function with .338 Lapus Magnum cartridges loaded to the Commission International Permanente pour l'Epreuve des Armes à Feu Portativs (C.I.P.) maximum allowed overall length of 93.50 mm
