The Accuracy International Arctic Warfare rifle is a family of bolt-action sniper rifles designed and manufactured by the British company Accuracy International. It has proved popular as a civilian, police and military rifle since its introduction in the 1980s.

The Accuracy International PM (Precision Marksman) rifle was entered into a British competition in the early 1980s as a replacement for the Lee-Enfield derived sniper rifles then in use by the British Army (e.g. L42A1). Accuracy International named this rifle the PM; the Army designated it as the L96A1.

A few years later, the Swedish military were also on the hunt for a new rifle, and Accuracy International entered an upgraded version of the PM, now known as the AW or Arctic Warfare. This was the start of the Arctic Warfare name, which would become the primary name of the rifle family despite its earlier names.

It has since spawned an entire family of sniper rifles using the Arctic Warfare name, and has been adopted by a number of other countries, including Australia, Belgium, Germany, Indonesia, Ireland, Latvia, Malaysia, Norway, The Netherlands, Russia, Singapore, Spain, Sweden and the United Kingdom. Other AI rifles descended from the L96A1 include the AI AE, and the AI AS50. Most Arctic Warfare rifles are chambered for the 7.62x51mm NATO cartridge, but it can also be fitted for other cartridges. It is mounted with a muzzle brake to cut down on recoil, jump and flash. Each country\'s rifles differ slightly.
