ACW-R

The Bushmaster ACR (Adaptive Combat Rifle), previously known as the Magpul Masada before Bushmaster and Remington took over production, is an assault rifle developed initially and proposed for the future replacement of the venerable M16 family of assault rifles. The ACR uses the standard 5.56x45mm NATO round but is also intended to be modifiable to employ the 6.5 Grendel, 6.8mm Remington SPC and the Russian 7.62x39mm M43 rounds. As with other conventional assault rifles, it uses a gas piston and rotating bolt.

It is known in the Battlefield series as the Adaptive Combat Weapon-Rifle, (ACW-R), similar to how the Magpul PDR is known as PDW-R in the Battlefield Series.

Battlefield 3
The ACW-R is briefly seen in the Close Quarters - Ziba Tower DLC Trailer, featuring the Reflex Sight, Foregrip and Suppressor attachments. It possesses automatic and semi-automatic firing modes. It is seen again in the Close Quarters - Donya Fortress DLC Trailer, this time around with only a Foregrip and a Holographic Sight attached.

From a performace point of view, the ACW-R performs much like the M4 with a high rate of fire and average damage, and very low amounts of recoil, even when fired full auto. However, it's worth noting that unlike other assault rifle caliber weapons, the ACW-R only causes 20 points of damage at close range and trails down to a higher-than-normal (for carbines) 16.7 at longer ranges, meaning killing an enemy from full health will take at least five shots to the torso, but only five to the torso at range, as well as three headshots at any range. It has been confirmed that in game to fire the 6.5 Grendel round, as said on the Battlelog Website. On the PS3, if the player has a controller with the vibration function on, the ACW-R will not make the controller vibrate.

To obtain the ACW-R, players must complete the Done Fixing assignment. The requirements for this assignment are:
 * 20 AT (Anti Tank) rocket kills
 * 30 kills with carbines
