ACR

The Remington "ACR" (Adaptive Combat Rifle), or Magpul Masada, is modern day assault rifle. It is an updated version of the Masada Adaptive Combat Weapon System, which was made by Magpul prior to their licensing agreement with Bushmaster, and later Remington. The weapon borrows traits from other firearms, most notably the ambidextrous operating handle in a forward position, similar to the SCAR, as well as a polymer construction akin to that of the Heckler and Koch G36. Its internal components are heavily influenced by the AR-18, an updated version of the AR-15 (the original M16 design) that was more reliable. The ACR is intended to fire with 5.56x45mm ammunition and uses M16 barrels, though it can have M16 type magazines inserted.

Call of Duty: Modern Warfare 2
The ACR is first used in the mission Cliffhanger, with a Red Dot Sight, Silencer and Heartbeat Sensor attached. Its damage is equivalent to the M4 Carbine but is much more accurate, having the least recoil of any of the fully automatics. It is one of the most reliable and versatile weapons in the game. The ACR has such low recoil that it can fire an entire magazine on full auto into a target smaller than a human head across even the biggest maps. Because of the ACR's high rate of fire and low recoil, it is more usable without Stopping Power than most guns. In multiplayer, the weapon is unlocked at Level 48.

The ACR has less recoil than and fires faster than the M4, meaning that the M4 becomes obsolete upon unlocking the ACR.
