The L96A1 British Intermediate Range Sniper Weapon (BIRSW) is chambered for the 7.62x51mm NATO (.308 Winchester).... 7mm Remington Magnum.... .300 Winchester Magnum... and of coarse the .338 Lapua (8.60x70mm).
Heres a history lesson... In early 1980's the British Army started the search for the replacement of the aging L42 Enfield sniper rifles. Main compettitors were british companies Parker-Hale with their model 85 bolt action rifle, and Accuracy International, with their PM rifle. Eventually, PM rifle won the competition and was accepted by British Army under the designation of L96
One of the most notorious features of the PM rifle was design of the stock. Instead of the solid polymer or wooden stock, PM/L96 used hollow polymer stock, made from two halves and assembled around aluminium bedding block, that extends to whole stock lenght. L96 also was equipped with backup iron sights.
In mid-1980s Sweden forces began their own quest for the new sniper rifle, that could survive heavy nordic environments. The AI again become the winner in this race with improved L96 design, named "Arctic warfare". In 1988 Swedish forces adopt AW rifle in 7.62mm NATO chambering under the designation of PSG.90. British Army, in its turn, also adopted this improved design under the designation of L96A1, as well as many other militaries and Law Enforcement agencies around the world. In 1998, the Bundeswehr (Germany Army) also adopted the AW Super Magnum rifle chambered in .300 Winchester magnum (germany designation 7.62x67mm) as Scharfschutzengewehre (sniper rifle - german) G22.
Built by Accuracy International of Portsmuth, England, this line of rifles is among the best in the World of sniper rifles today. This rifle can shot less than 2" (51mm) groups at the distances of 600 yards (550m), using boat-tail match ammunition. Arctic Warfare is a line of 5 rifles. Original Arctc Warfare was designed for the British military. It gained its designation by special anti-icing features, allowing sniping operations to be carried out under Arctic conditions as low as -40C (-104F)! Other models are Police (AWP), Suppressed (AWS), Folding (AWF) and Super Magnum (AW SM). Three first rifles designed for 7.62mm NATO ammunition, while Super Magnum can be chambered in .338 Lapua Magnum, .300 Winchester Magnum and 7mm Remington Magnum. AW has a 26" (660mm) barrel, AWP has 24" (609mm). AW SM barrels available in lentths from 24" (609mm) to 27" (686mm). The standart scopes supplied by Accuracy International are Smidt&Bender 3-12X variable or the Leupold Mark 4 fixed 10X scope.
