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


The M4A1 CCO SD is a silenced assault rifle with a red dot sight and camouflage paint job. It's currently the only M4 assault rifle with a silencer in DayZ, and can only use SD magazines.

Because it's a silenced weapon and has an attached aimpoint sight, it's a very desirable weapon for killing zombies, as it can clear an area without attracting attention. In an organized squad, one player armed with this weapon can safely clear the way for the rest of the group.

I found mine in a tent on an island. Then I shot the owner of the tent in the face with it. Good times..

For those wondering, this weapon is the M4A1 CCO SD. This rifle is only found in the barracks, but it isn't too rare. Personally, I believe this is the best variant of the M4 next to the M4A1 HWS M203, and it is the strongest suppressed firearm in the game, making it perfect for taking out players and zombies at medium ranges. Not only does it look great, it shoots great too. With the Aimpoint, one doesn't have much trouble shooting targets at 100-150 meters. I love this gun!

Got mine from a tent in Cherno, looked like a bandit camp.. I'm ready to give the mags back :)

This is my go-to gun for Zombie disposal now. The CCO makes it a breeze to get those headshots at mid to close range, and ammo for it is much more plentiful than for other SD weapons. The only downside is that the SD rounds actually travel much slower than normal STANAGs, meaning it doesn't quite have the effective range of the normal M4. I'm running it as my secondary right now alongside my sniper rifle. Anything too far for the M4SD is in M14 or DMR territory anyway.

Also, if you're looking for ammo for this gun, keep an eye out for the 5.56 ammo boxes in the barracks and at heli crash sites. The last one I found had 20 STANAG and 10 STANAG SD mags in it!

I currently have an "M4A1 CCO SD". It looks just like this. Is there a "camo" variant, or does the name need to be changed?

By Thorgold on 2012/07/07 at 11:51am

@mook First, Freeside Traders has a few guys selling m4 SDs, and they're always buying sd mags. And I know that feel - last life I had an m4, could only find am mags. Now I have an ak and I can only find stanag and m240 belts :/

For the gun, though, it's probably the best silenced weapon you can get. I find it's a tad easier to get ammo for than the Bizon or the MP5, plus its Aimpoint, longer effective range, and more DPB make it a more versatile weapon against zeds and players.

This assault rifle, in my opinion is the best city raiding weapon in the game. The Close Combat Optical Site (CCO), does an excellent job providing a large field of view when pulling the weapon upon a target and even seeing other targets in the proximity of your main target. Also, since the weapon only uses SD rounds, the scope is zeroed for these rounds. Put that red dot on your targets head and down it goes. No compensating with SD rounds in a non silenced weapon. Of course this weapon being designed for close quarters is relativity accurate up to about 150 meters with a novice marksman, which in a city you normally wont be shooting further than this.

The weapon being silenced is also what makes it an excellent choice for city raiding. You can be taking shots at zombies in Cherno, get your self cornered by one crazy freak agro with the zombies, switch to full auto and mow them down. I find double taps to a body will take a zombie down. Then not even three minutes later, hear an AK go off about 200 meters away. Knowing they haven't heard you, you can either hunt them down, or make a run for it.

I found a ammo crate for it, put all the SD mags in my backpack, then found the M4A1 CCO SD, was so happy, later I accidently "DROPPED" destroyed and i felt like a retard.

By lappyroots on 2012/10/02 at 8:16pm

Pulled mine off a guy in the Cherno FD who had just been sniped, then used it to blast the sniper in the face as he came through the door. Ah, good times.

By termina33 on 2012/09/17 at 6:05pm

I spawned in Three Valleys and on my way to Elektro, a dude spawned in, started shooting me and i told him i was friendly and he dropped a M4A1 CCO SD with 4 mags and a M9 SD with 6 Mags.

By Mook on 2012/07/06 at 5:57am

My favourite gun so far, ran out of ammo with it, left it in my backpack, swapped backpacks, lost it due to the glitch. I WANT IT BACK!!!! :P looking for it ever since. Doesn't help that I now have 10 SD clips for it, but no gun. Using the M4A3 atm, until I get my baby back.

By Nostradam on 2012/12/13 at 10:01am

I was a fresh spawn on Namalsk. I ran up to southern army base and found this gun with 1 clip in one of the barracks. I was checking the tower and I hear a chopper incoming and it landed at the helipad there. I walk out on the third tier of the tower and see 3 guys, one stayed with the chopper and 2 ran into the barracks. I was shivering my ass off with the gun but didn't miss the pilot once(he got out to clear some zeds). Put 3 into his chest. The silenced must of worked on these guys cause they waited 10 minutes and had no clue where I was. Finally they bolted for their chopper(I really mean my chopper), I killed the first one quickly and tagged the last guy in the heel just as he was about to run in the barracks again. I didn't hear any shots to kill the 5 zeds chasing him. So I assumed he was passed out, I climb down and finish him and the zeds off. When I was looting, a guy with a PDW ran in and we emptied our clips at each other from 5 feet away. He won. 4 people to loot and a chopper, his lucky day. Well the moral of the story is this gun seems amazing to me when being stealthy on semi but absolute **** close range on full.

I finally changed the text from M4A1 Camo SD to the corrected M4A1 CCO SD. Is the title able to be changed?

By SniperOfBalota on 2014/03/16 at 8:34pm

i love using this gun at Balota on crowded servers for zombies and players. I sneak up around 20-30 meters behind players and let the recoil lead up the the crucial headshot (on full auto). It's really funny because they do not know where the gunfire is coming from nor can they hear it.

By -YLH-Tlomz on 2013/09/05 at 1:01am

I love this gun. I found it in NWAF southern barracks and I used it to escape the airfield. It handles zombies very well and players don't know what happens when it hits them.

By Guui16PT on 2013/06/01 at 8:09pm

Best Gun of the DayZ !

By IYIxChinaMan on 2013/04/09 at 12:43pm

I pop brains with this gun. And no-one even knows what hit them <3

By Alpha-Nine on 2013/03/16 at 1:55pm

This can also use the G36-SD ammo

My Double-Barreled Shotgun got transformed into this. I never knew if it was a bug or a hacker, but it was a hell of alot of fun bragging to my friends about this.

By ketchup504 on 2012/12/08 at 2:27pm

Carried me through many medic missions alongside an M9SD. Fantastic weapon for zeds.

By hobo on 2012/12/03 at 1:04pm

good for the stealth aspect comes in handy when going into areas with alot of bandits or hostile survivors. Ive slipped in and out of nwaf when there was a crew of about 3 bandits there, managed to steal one of there vehicles, if it werent for having this gun they would of seen me and probably killed me. Other times for the 1v1 situations this gun does not always deliver, ive had a guy empty an entire clip in me with this gun, got hit 2-3 times managed to survive run into a building, and had a grenade waiting for him.

By Philippe on 2012/12/03 at 9:24am

Much better than the Bizon in every possible way. Best gun in the game for getting rid of zombies. Have a second gun that is better at PvP like the M14 or a sniper rifle and you're all set

By Morgothom on 2012/09/10 at 5:42am

Looting Tents at Stary. Hearing chopper. Went hiding. Heared crash. Went investigating. Found a Bushwookie with this baby plus 12mags. trolololo win :D

By Mouse on 2012/09/06 at 3:44pm

Got a hold of two in a glitch with a buddy of mine on Lingor Island. Zombie holocaust the likes of which have not been seen before. This will down them in one hit to the head, though factoring bullet drop can be a concern. Almost never took three shots to kill; probably hits on the limbs at that point.

By jokerzhe on 2012/09/02 at 5:34pm

If you see this, drop whatever you have to get it other than as50 or l85, this is the gun to have, a silencer and a sight is a big deal in this game

By mukaluk on 2012/09/02 at 11:22am

Found one of these on a tent near barizino took it loved the gun but died in a hlicopter crash an lost the gun.

By lonewaft on 2012/08/03 at 1:48pm

It's an alright gun. Replaced my M16A4 with this, and not too satisfied. Gun is pretty weak, and not AS quiet as i thought it'd be. Zombies can't hear it, but for players, the sound is pretty sharp and you could tell that a silenced weapon was fired nearby. overall power 6/10 accuracy 8/10 rate of fire 8/10

By Thaua on 2012/07/22 at 2:50pm

Tested this on the range. I'd say the effective range is 150m, since you have to point the reticule above the target in order to hit it, losing reference to an accurate shot. Still, is pretty easy to hit a target 200m away. The standard iron sight can be used to hit a target accurately 350m away.

By SatiX on 2012/07/11 at 8:28am

2721 dmg/per hit

By StealthAssassin on 2013/05/24 at 4:27pm

I used to got one, untill a dude in ghillie sneaked behind me with AKS-74 Kobra...

By Solacelawlz on 2012/08/21 at 3:11pm

Fantastic Gun! By far my fave town raiding gun (or overall gun when I'm not svd'ing it up) because of it's accuracy and silence. If you're good at maneuvering while proned with this babe you can run right through a town full of zombies w/o drawing any attention what so ever destroying them all. Not to mention always nice when survivors see zombies dropping but don't know how so they go to inspect and you shoot them too! >=) I know, I know... yes... I'm a dirty bandit I'm sorry but not really =)

I find the bottom barrack at the northwest airfield a great place to farm ammo for this rifle as well. I check out that barrack daily for more ammo (currently at 17 clips). I got my rifle by shooting someone in a guillies suit in the face and taking the 10 clips he had on him as well.

If you get your hands on this gun, you shouldn't be disappointed!

By M4RCCK on 2012/07/30 at 7:30am

This gun was the second i had whit sights (good sights) the other had an thermal...
