Kastov 74u

Featuring the base components of an AK-47, it’s no surprise that the Kastov-74u is one of the strongest assault rifles on this list. The Kastov 74u is so special due to its SMG-like qualities, giving players access to an assault rifle that has the mobility of a submachine gun. Make sure you equip this weapon on close-quarters maps to get the most out of the best Kastov 74u loadout.

TAQ 56

The TAQ 56, or the SCAR as it was previously known, is a slow-firing behemoth of an assault rifle. With a difficult recoil pattern to control, it can be an unwieldy beast, but in the right hands is absolutely devastating. For the ideal attachments to bring that recoil in line, we have the best TAQ 56 loadout in Modern Warfare 2 here.

Lachmann 556

Ever used the M4 and wished it could land shots from further away? Just switch to the Lachmann 556 to have your prayers answered. This assault rifle sacrifices mobility for accuracy stats, making it a real threat when you can spot enemies in the distance. You won’t be able to sprint out of the way if someone manages to sneak up behind you, so you may want to equip a shotgun or SMG for these situations.
