M24 A1 Sniper Rifle
.300 Winchester Magnum (M24A1 - 800m) or .338 Lapua Magnum (M24 A3 - 1,500m)
The M24 Sniper Weapon System (SWS) is the military and police version of the Remington 700 with Leupold sight and Harris bipod adopted by the US Army as their standard sniper rifle in 1988 and still in use in 2011, although modern variants look nothing like the original.
It is also used by Afghan National Army, Brazil, Hungary, Israel, Japan and Lebanon.
