RSASS

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

Campaign
The RSASS appears in "Eye of the Storm", with a variation of a Hybrid Sight and suppressor. It is the only sniper rifle that has the Hybrid Sight attached, though this is applicable to single player only. It is also seen unsilenced and without Hybrid Sight during the level. It is also found in the mission "Stronghold".

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 two hit kill requirement is relatively easy to achieve, since consecutive shots are more manageable with this weapon. Playing Hardcore gametypes will also mitigate the damage, and in fact makes it one of the better sniper rifles, considering the fire rate and magazine size.

One other minor disadvantage is that when spawning with the RSASS, the player receives only one spare magazine instead of the default two. However, due to the RSASS's high magazine size, one still spawns with more ammo than with most other sniper rifles.

The Suppressor is a great choice, the RSASS already takes 2 shots to kill and works well with Assassin Pro. The Variable Scope is also good, as it adds versatility to the weapon, allowing to hit targets easily at any range. The ACOG Scope, on the other hand, is useful if one wants to use the RSASS up close, although the MK14 is more suited for CQB.

The RSASS is better or the same than the Dragunov in almost every aspect, having less recoil, larger magazine size, faster regular and empty reload times and more starting and maximum ammunition. However the Dragunov is unlocked earlier than the RSASS.

Because the MK14 has such high damage, it may be advisable to use it over the RSASS with ACOG because it also has a 20 round magazine and will kill in two to three shots. It also has a smaller 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 two shots at that point.
