308 firing pin

The Accuracy International Arctic Warfare rifle is a bolt-action sniper rifle 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 rifles have some features that improve performance in very cold conditions (which gave the rifle its name) without impairing operation in less extreme conditions.
Arctic Warfare rifles are generally fitted with a Schmidt & Bender Police & Military II (PM II) telescopic sight with fixed or variable magnification. Variable telescopic sights can be used if the operator wants more flexibility to shoot at varying ranges, or when a wide field of view is required. Accuracy International actively promotes fitting the German-made Schmidt & Bender PM II product line as sighting components on their rifles, which is rare for a rifle manufacturer. The German and Russian forces preferred a telescopic sight made by Zeiss over Accuracy International's recommendation.
