This page contains information about the mod version of DayZ. Standalone information is available here.


The M4A3 CCO is a modified version of the M4A1 with a flashlight and CCO (Close Combat Optic) red dot sight attached. The sight provides no magnification, but does help to reduce the recoil on the weapon. The desert camouflage pattern painted on it is slightly less visible in the brush, making it a desirable assault rifle for those wearing a Ghillie Suit or Camo Clothing.

The attached flashlight, ability to use silenced rounds, and slightly lower recoil make this the best medium range weapon in the game for operating in the dark.

Usage tips:

  • Although not a silenced weapon, it can use 30Rnd. STANAG SD ammo which produces a silenced audible range effect for zombies while players hear an unsilenced report, however when using 30Rnd. STANAG SD ammo the red dot is not where your bullet will hit, the actual hit zone is about 3/4 of the distance from the top of the iron sight pin to the red dot ABOVE the dot
  • The flashlight attached to the weapon has the same drawbacks as the standard Flashlight and so should be used with care.
  • Depending on the HDR setting of another player or whether they are using NV Goggles, shining the flashlight directly at them may be blinding while also lighting up the target for improved aim with the rifle.

For those not attentive - YES, this is essentially M4A1 CCO + Flashlight :)

Out of all of the M16/M4 variants in the mod, this is my favorite. The illuminated reticle is nice, but maybe not as nice as the KOBRA, and the flashlight gives it significant utility during the night. The snazzy camo point job is a nice bonus, but doesn't have much practical value in the game.

Like all of the 5.56mm assault rifles, the sound of the report seems to be sharper and more distinct to the ears of other survivors when compared against the AK-74 and its variants.

The M4A3 CCO is a great weapon until you get the suppressed version, as it's flashlight gives a good field of vision at night, and the Aimpoint red dot allows for quick target acquisition. This gun is perfect for clearing and securing buildings.

Can anyone confirm that this weapon has better full auto control given the forward grip

this gun helped me take out an entire bandit squad, i love it

Extremely good weapon for people like me, who favor AR's and often play during nights. The STANAG's are easy to find, CCO-sights are just fine and the flashlight is really useful when closing in on lootable areas (Small tip: Bind the key to a button you can quickly press when needed). This, combined with some flares has helped me through some tough fights against people who are using NVG's.

By LordMuffin on 2013/03/06 at 5:14pm

Found one of these in one of the Elektro fire stations. I have about 6 or 8 mags for it as well. This is definitely a personal favorite.

By LivingPixel on 2013/03/01 at 8:06am

It missis with 30Rnd. STANAG SD; Is this a bug, or it it ment to be so the weapon isn't too overpowered?

By Cyphex on 2013/02/09 at 10:49am

just murdered 4 people with this in 5 minutes. scope is sick nasty

By Dude on 2013/02/07 at 1:31pm

@Redrick Is not no accurate, just SD ammo have less power. M16 ACOG and other STANAG using weapon you must aim always differend, when using STANAG SD ammo. M4A3 CCO is my favorite main weapon, if I have not M4A1 CCO SD yet.

By NomNomMeatball on 2012/11/28 at 6:30am

After playing for hours, and going all the way to the NW airfield, I have finally found one of these. When I play the ACE mod on ArmA 2, I'll always take the M4A1 CCO SD. This gun is very much like it, except it's unsilenced. It's an amazing assault rifle, it's dependable, ammo is easy to find (Even in cities from fire stations) and it packs a punch. If you are panicing from a firefight, just go full auto and use the clip on a guy. There's always more ammo to be found. The sight is very helpful at spotting targets, and even better for picking headshots on zeds. I would recommend this gun over any other assault rifle (That I've found so far).

By Dude on 2012/09/19 at 6:31am

I like it very. They said, effective range is 300m. Maybe, but. last night I shot guy on North Airstrip, was ~400 m. First I tried with M14. Few shots and nothing. I had no more ammo (M14), so little angry I changed weapon for my M4A3 CCO with stnandard STANAG ammo. First shot and headshot ;P I think, It is maybe not very accurate over 300m, but still usable. And I just very like this weapon.

By Falco on 2012/09/13 at 10:38pm

had the choise between this, an m4a1 cco sd and a ak 74 kobra, i chose this because it can fire both subsonic and normal rounds while the sileneced m4 can only fire rare silenced rounds and the kobra does less damage even though it looks cool

By LagmasterShaun on 2012/08/26 at 1:08pm

Just ran over some Bandit just stupidly standing in the middle of the road and he had this Happy days been north west airfield 10 times looking for this and find it on a guy first still very good gun best so far for me

By PygmyJess on 2012/08/21 at 7:21pm

I found an M4A3 CCO in the military tents, but instead of the reticle shown in the pictures it is just a normal red dot. I use SD rounds in it and I definitely recommend aiming lower to kill zeds compared to normal rounds. I lost my NVs and had to use the flashlight which was very useful.

By That1RandomTree on 2012/08/20 at 9:25pm

This is a personal favorite mainly because of it's sight and accuracy. The flashlight and camo are cool additions to it though making even better.

this gun have great accuracy when shooting in fully automatic. the sight just wont move form the target! great gun!

By AidenM17 on 2012/08/08 at 12:30am

I found two of these just 10 minutes ago with about 15 mags :D I was held up in a fire station in elektro looting some dead bodies that i found when i heard a car so i looked out the window and there was a car and two people got out and immediately started shooting at me so i shot a few winchester rounds into them, went down, found they both had M4A3 CCO's on them with a hell of a lot of ammo and now i have a car as well :D

By CyberGhost on 2012/08/05 at 5:54am

Just found one like 10 mins ago at NWAF, this gun is very nice for clearing places, and it's flashlight is very helpful, u guys should try this :D

By dziurdamer on 2012/08/03 at 1:59am

I found this beast on a deer stand, and i'm pretty happy of owning this one :D

By Brad on 2012/07/30 at 3:45pm

I've noticed when loading SD (subsonic) rounds you'll need to aim lower in order to hit closer targets. If target is within 50m I'd advise aiming at the chest or lower neck to get headshots.

Picked this up the other night from a heli crash and trying not to lose it!! Sooooo much ammo around for it too :)

The red dot shoots slightly higher when loaded with a STANAG SD. It's best to just use the regular STANAG. Unless you want to stay quiet to zombies that is. c:

Generally, a useful gun for the rifleman on your squad. Allows for effective player/zombie engagement at ranges up to 400 meters (depending). Noisy, but followup shots generally find their targets. Also an excellent gun for when the whole group aggros and everyone needs to spray and pray.

By DKSledgehammer on 2013/03/15 at 9:47pm

So...when firing STANAG SD rounds, it actually shoots somewhat above the dot?

By Redrick on 2013/01/31 at 9:35am

The most stylish weapon to use on Takistan servers. It has better looks than the M4A1 CCO and its recoil might be a wee little bit lower, but the M4A3 is notoriously inaccurate with SD ammo. For headshots, aim at the chest. Doesn't matter much at close quarters though where this rifle is in its element.

By haraldmartin on 2012/12/22 at 12:10am

I love this weapon ! I've found it in Panthera Island in "Asabana Army Base" in the "Barracks"

By Bloomy on 2012/08/29 at 6:19am

I found this one at firestation at elektrozawodzk
