Accuracy International is one of the most well-known manufacturers of sniper rifles in the global firearms market. The Arctic Warfare Magnum is a superpowered version of their already-popular Arctic Warfare weapon. The original AW was overhauled to work with Winchester or Lapua Magnum-type cartridges for that extra punch, creating the AW Magnum.
It was first fielded in 1996, and continues to be fielded in 18 countries around the world. For two decades it was one of the most popular choices for snipers until recently. This weapon was used by snipers in recent engagements like Operation Enduring Freedom and Operation Iraqi Freedom during the early 21st century.
The .338 Lapua version more powerful than the Winchester Magnum, with an effective range comparable to the .50 BMG round. Although it can penetrate most armored glass, is more practical for targeting combatants rather than materials, due to the lower kinetic energy and penetration power.
The Arctic Warfare Magnum had set the official record for the longest-range kill in 2009. While the record has since been surpassed, this weapon continues to be used by world-famous snipers like Craig Harrison of the British Army, who has used it to kill two Taliban combatants at nearly 2500 meters with this weapon.
