RSASS

The RSASS is a semi-automatic sniper rifle that appears in Call of Duty: Modern Warfare 3.

Multiplayer
The RSASS is a sniper rifle unlocked at level 44 in Multiplayer. It has the highest magazine capacity and lowest recoil among sniper rifles, making it the most user friendly weapon in this category. This, however, comes to the cost of having the lowest damage too, although this shouldn't be too problematic since the 2 to 4 hit kill requirement is relatively easy to achieve, since consecutive shots are more manageable with this weapon. Headshots are still one-hit kills.

The Silencer is a good choice, since it will usually kill in two shots anyway. The Variable Scope is also good, as it adds versatility to the weapon, allowing to hit targets easily at any range.

The ACOG, on the other hand, is useful if one wants to use the RSASS up close, although the MK14 is more suited for CQB. Because the MK14 has such high damage, it may be advisable to use it over the RSASS because it also has a 20 round magazine and for the most part will kill in 2-3 shots. It also has a small hipfire spread, making it more capable in CQB. The RSASS, however, has higher damage at range, has a sniper scope, and provides a handy ghillie suit.

Survival Mode
The RSASS is unlocked at level 29 in Survival Mode. It costs $2000 from the Weapons Armory. It is not good past the medium troops, due to its inability to kill in 2 shots at that point.

Trivia

 * When mounted with the Hybrid Sight in singleplayer, the gun is tilted to its side, due to the sight being mounted on the side of the gun.
 * The RSASS has the Remington logo engraved on the left side of the gun, similar to the ACR and the MSR.
 * The selector switch on the RSASS is always on safe.
 * Its the only Sniper to get the Hybrid Sight, although its only in Singleplayer.
 * When prone with the Heartbeat Monitor attached, only the top half of the monitor is visble. This isn't a major problem, as you'll still be able to detect incoming hostiles, as long as they are not right on top of you.
 * The RSASS, along with the Dragunov, has a Damage Power of 70.
