M1903 Springfield

The M1903 Springfield is an American Bolt-Action Service Rifle heavily based on the German-made Mauser Karabiner 98. The Springfield had replaced the older Kragjorgensen Service Rifle used during the Spanish Civil War. The Rifle used the exact same action and operating system as the Mauser Karabiner 98, but used different iron sights, as well as using the American cartridge of .30-06. It was used extensively as the standard issue rifle of the United States Army during the First World War and used as a Sniper Rifle during World War 2, being replaced as the standard issue rifle by the M1 Garand.

Battlefield 1943
The Springfield is the primary weapon issued to the USMC "Scout" class. It is the most powerful infantry weapon in the game (tied with the IJN Type 98, for faction balancing) being able to kill in 2 body shots or a single headshot, but it's extremely low rate of fire (taking around 2 seconds to pull the bolt) can make a target easily run away after being hit by the first shot.

Trivia

 * It is a direct equivalent (in stats) to the IJN Type 98 Sniper Rifle.
 * If you look closely at the Battlefield 1943 Springfield Rifle (especially the metal parts of the gun), it will look more like a mix between the German Karabiner 98 'Kurz' and the Russian Mosin-Nagant, rather than a real M1903. The only difference it would have between a K98 would be the optic used, which was almost the entire length of the gun.
