“The Portsmouth company, Accuracy International (AI), equips the British Special Boat Service and Special Air Service with sniper rifles. In 2008, it signed a 3.7 million-pound contract to supply almost 600 sniper weapons to the UK Ministry of Defence. What came out of the SEALs’ approach to AI was a new gun.

“The fact that such a small company can be a world-beater in the manufacture of quality weapon systems in a market dominated by huge American and European companies is a huge achievement,” says Color Sergeant Lee Chevenix, a British Army sniping-team instructor. “I know from first-hand experience how revered the AI product is, even in the States, where traditionally U.S. producers are favored.”

AI’s weapons are now part of long-range sniping lore. Craig Harrison, a British Army sniper from the Household Cavalry, hit two Taliban machine-gunners with two consecutive shots at a range of 2,475 meters in Helmand province, Afghanistan, in 2009. Inadvertently he had taken the world sniping record using an L115A3, the 0.338-inch caliber military sniper-rifle system made by AI that is now standard issue for the British Army.”
