MSR

The MSR is a high damage bolt-action sniper rifle that appears in Modern Warfare 3.

Call of Duty: Modern Warfare 3
"A master of the one-shot kill, the bolt-action MSR deals exceptionally high damage from exceptionally far distances. Paced shooting and an even-tempered approach ensures any MSR sharpshooter success no matter the range."

- DewXP description

Singleplayer
The MSR appears in the campaign level Iron Lady, where it is useful for picking off enemies at range in the ground-based section of the mission.

Multiplayer
The MSR is unlocked at Level 66 in multiplayer. It is the very last sniper rifle to be unlocked. It is nearly identical to the L118A, but has a much faster bolt pull. Its reload is fairly fast as well.

As with the other sniper rifles, Quickdraw is a great perk to use to speed up its lethargic aim time. Sleight of Hand Pro can also be useful, as one can quickly switch to another weapon in a close quarters pinch, and the faster reload can save one's life when faced with many enemies at once.

Survival Mode
The MSR costs $2000 to buy from the Weapons Armory. It is unlocked at level 7. It is not recommended past the waves of the medium troops, when it can no longer deliver one hit kills.
