AS50

The AS50 is a semi-automatic high-powered sniper rifle that appears in Call of Duty: Modern Warfare 3. The AS50 was first seen at Call of Duty XP.

Call of Duty: Modern Warfare 3
The AS50 is featured in Spec Ops and Multiplayer, but is unavailable in Campaign.

The AS50 appears in Spec Ops mission "Smack Town".

Survival Mode
The AS50 is available in Survival Mode from level 42 and costs $2000.

Multiplayer
The AS50 is unlocked at level 22 in Call of Duty: Modern Warfare 3's multiplayer. The AS50 has low recoil, high power (a one-shot kill to the head, neck, shoulders, chest, and stomach), and a five-round magazine. The AS50 has a unique scope with very low zoom, making the rifle more suitable for use at closer ranges than other sniper rifles. However, the lower zoom means that it is less useful at longer range.

The Variable Zoom can be very useful on the AS50, as the scope retains the close range zoom, but can be zoomed in for taking out players at longer ranges that otherwise the default scope would have trouble hitting. Extended Magazines is another good option, as it will assist in prolonged engagements that otherwise would require constant reloading. On the other hand, the Silencer is not recommended as it severely decreases the chances of a one-shot kill, which is one of this rifle's key advantages.

Trivia

 * AS50 has the lowest default zoom level of sniper rifles in the Call of Duty series, having the same zoom level as an ACOG scope.
 * The AS50 is modelled with an ejection port on each side; while the port to the left opens and closes when the action cycles, the rifle actually ejects spent casings to the right
 * This, along with the L118A are the only British weapons not to feature the SUSAT optical scope.
 * The AS50's reload animation resembles that of the Barrett .50cal.
