Call of Duty: Advanced Warfare has seen the introduction of multiple weapon variants of a single weapon. These variants, for the most part, have changes in their stats that from the base weapon. The following are the effects of the changes on the weapon variants.[1]
Effects
Damage
Affects damage values (increase/decrease in damage, and which values are affected, vary from gun to gun), multipliers (XMG, EPM3, and sniper rifles), Penetration (ARX-160 Steel Bite, MK14, and Sniper Rifles), Pellets (adds/subtracts one pellet per each damage point- Shotguns only).
Range
Increases/decreases the minimum and/or maximum ranges of weapon variants by 15% (Note: On shotgun variants where the medium damage is decreased, this affects how far the shotgun can actually shoot and hit a target).
Fire Rate
Increases/decreases fire rate (fire time), intro fire rate, and burst delay (as well as reload time on the MORS). Increases/decreases overheating on Directed Energy Weapons (EM1, EPM3, and AE4).
Mobility
Increases/decreases ADS time by 10%, and increases movement speed by 2% (Shotguns, Sniper Rifles, and the SAC-3).
Handling
Increases/decreases Sprint-Out time (Shotguns, Sniper Rifles, and the RW1) by 10%, and Hip Fire spread by 10%.
Accuracy

Reserve Magazines

Note
One should be aware that the in-game stats shown do not always reflect how the guns actually perform. For example, the Pytaek 'Loophole' is depicted as having decreased handling in the stats, where as in-game it is actually increased.
