M40

The M40 is a bolt-action sniper rifle designed in the mid-1960s by United States marines who were modifying Remington 700s during the Vietnam War. It fires 7.62x51mm NATO rounds from a 5-round box magazine at an effective range of 1000 yards.

Battlefield Vietnam
The M40 is issued to US Army and MACV Scout kits on certain maps. It has very high multipliers, a low rate of fire, high recoil, good accuracy and a 6X scope meant for long range engagements. Its high damage can kill an enemy in 2 body shots or a single head shot and its accuracy will make it so it can easily hit a target from 200–250 meters away. Although being difficult to use in close-quarters due to its low rate of fire, the small cross hairs and high damage can prove to be effective when no-scoping. The M40 can somewhat be considered an equivalent to the Viet Cong M91/30.

Battlefield: Bad Company 2: Vietnam
In Battlefield: Bad Company 2: Vietnam, the M40 is a weapon issued to the Recon kit. It is the only bolt-action sniper rifle featured in the expansion. It is capable of one-hit kills at all ranges in Hardcore mode, even without Magnum Ammunition, due to its minimum damage being 70. It is equipped with a 6x scope by default, but it can equip a 12X High Power Scope instead if the player chooses said specialization.

On the left side of the rifle, one can see that it says "Hell Sucks!" scratched in.

Battlefield 3
The M40A5 is a bolt-action rifle available to the Recon kit and Henry Blackburn in a Campaign mission, Night Shift. It is unlocked at 104000 Recon score.

An incredibly accurate rifle, the M40A5 currently serves as the primary Sniper Rifle for the USMC. The M40A5 is equipped with a Rifle Scope (8x) by default."
