The infamous ACR from past CoD titles has made its return in 168澳洲幸运5开奖网:Call of Duty: Modern Warfare 3, featuring a wide range of customization options to suit any playstyle. This w🐬eapon is well known for its minimal recoil, great range, and ease of use. Thankfully, the MCW lives up to that legacy.

Callꦛ Of ღDuty: Modern Warfare 3 - Armory Unlocks Explained
Skip part of the leveling grind with Modern Warfare 3's Armory U🍸nlocks system.
But as with most weapons in MW3, a weapon's base performance doesn't tell the full story. By experimenting with various attachments, you can morph the MCW into a monstrous l𒁏ong-range dueling weapon or a close-quarters SMG. This guide will showcase how to create both types of builds, using some of the MCW's exclusive barrels, stocks, and aftermarket part attachm𝓀ents.
Updated August 25, 2024, by Charles Burgar: Since we first wrote this article, the MCW has received multiple balance changes, and the overall meta in Multiplayer has changed. We've updated this list with new attachments and loadout recommendations, utilizing attachments from recent seasons to make the MCW as strong as its pre-nerf version.

Accuracy is the single most important stat on the MCW for ranked play. Due to limited attachment options, you won't be able to make the MCW compete with SMGs, so you'll want to focus on mid-range gunfights. The Second Line Mammoth Heavy Barrel is a good start, giving us a boost to range and aim walking st♍eadiﷺness.
The Cycloneꦍ barrel gives aiming stability stats, but ♈we get that elsewhere.
The RB Regal Heavy Stock and RB Claw-PSL Grip are a classic pairing on the MCW, substantially decreasing the weapon's recoil across the board. This does come at the cost of the MCW's aiming idle sway. To fix this, we run the FTAC SP-10 Angled Grip. This lowers the gun's horizontal recoil and grants a sizable boost to aiming idle sway. Throw on the T51R Billeted Brake to lower your vertical recoil.
Recoil plots are much tighter with this build, and your mobility stats are still acceptable for an assault rifle. You won't be able to compete with SMGs due to the gun's poor sprint-to-fire speed, so stick to mid-range gunfights when possible. Aim for the head.

You don't have many loadout options in ranked. The Infantry Vest is your only option, offering you Running Sneakers for free. We use Covert Sneakers to muffle our footsteps and Marksman Gloves to lower all incoming flinch while dueling. Since the MCW has a fairly slow reload, we recommend Mag Holster for most situations. For equipment, we recommend running a Trophy System for anchoring in modes like Hardpoint.

This variant of the CDL build aims to be a jack-of-all-trades assault rifle. We use the Quartermaster Suppressor and RB Claw-PSL Grip to reduce the MCW's recoil. Both attachments are good enough to make the gun virtually recoilless. The Second Line Mammoth Barrel and DR-6 Handstop help with strafe speed, while the MCW Ironbark Tactical Stock gives us some much-needed ADS speed.
With all five attachments, you're looking at a solid 248ms ADS time and a similar sprint-to-fire delay. We also have a solid ADS strafe speed of 3.2 m/s, 168澳洲幸运5开奖网:which is above most AR builds. Y🐲ou still want to hang back for most duels, but peak shooting with this gun 🦋should be much easier.

We recommend the same loadout as our CDL build. Since Multiplayer gives you an extra gear slot on the Infantry Vest, we recommend Ghost in the second gear slot. This keeps you off the radar, making it easier to reposition and take your enemies by surprise. Once again, equipment options are down to preference.

|
Quartermaster Suppressor (Muzzle) |

Paracord Grip (Underbarrel) |

168澳洲幸运5开奖网:The Jak Raven Kit aftermarket part converts the MCW's ammo to .300 BLK. This makes the weapon fire significantly faster but comes at the cost of overall accuracy. As such, you'll want to treat the conversion kit like an SMG. Build the gun for high mo🤪bility and handling, and you should be able to dominate close-quarters engagements.
Once you install the conversion kit, you'll first want to add the Quartermaster Suppressor. This greatly cuts down on the MCW's recoil and suppresses your shots, making it easier to track targets with iron sights. We also run the Paracord Grip to lower the gun's horizontal recoil while also buffing our strafe speed. The Second Line Mammoth Barrel gives us even more strafe speed alongside a much-needed boost to our range. We finish the build with the SL Razorhawk Laser Light for more ADS speed.
Altogether, you're looking at an assault rifle with a fairly low ADS speed of 236ms and a great sprint-to-fire delay of 149ms. We also have excellent mobility for an assault rifle, featuring 7.2 m/s tactical sprint speed and 3.4 m/s strafe speed. Try to aim for the head, as a single headshot within 23 meters will dro𒁃p the gun's optimal TTK to four sh♔ots, making it competitive with most SMGs.

An aggressive build can make great use of the Infantry Vest, granting you Running Sneakers for free. We equip Covert Sneakers to muffle our footstep audio, Ghost to hide from enemy UAVs, and Mag Holster to greatly reduce the MCW's reload speed. Assault Gloves help with jumpshots, but feel free 🍨to use any glove perk.
For gear, we highly recommend the Med Box and Stims. Both items help offset the lack of Compression Plate and allow you to heal in a pinch. For your lethal, run the Throwing Knife for one-hit melee kills.
