In the multiplayer mode of Call of Duty: Modern Warfare 3, the player earns XP while doing various tasks throughout playing. Being one of the only bolt action snipers, I find it and its brother, the MSR, to be the best sniper rifles in the game, due to their ease of use and comfort. The L118A sniper rifle is one of the most popular Quick-Scoping snipers in Modern Warfare 3. KSG is strong, but if you miss the kill on shot #1, you’re probably dead.
Then USAS (some call this best), semi spammable. Striker is arguably still the best due to spammability.
The AK-47, QBZ-83, and Groza will all be slightly less effective from afar when using Suppressors. However, a select few Rifles actually had this stat increased, adding to the range penalty rather than reducing it. Activision All seven Assault Rifles have been tweaked in the Black Ops Cold War Season 4 update.
