Type 95 with red dot site and rapid fire, or ACR with red dot and extended mags.

FAD holo sight with silencer, or ACR hybrid sight with silencer

Everyone uses it but the ACR with Red Dot and Silnecer is my weapon of choice. Very close to the ACR and an often under used weapon is the M4A1. Some of the best weapons in this game, and often underated, are the ones you get early on. M4A1 and UMP45 to name but two.

The laserbeam aka ACR with a silencer and Impact. Scar extended mags and the g36c are good too. Fad for rushing. Mk14 for the bigger more open maps.

The t95 is probably the best core gun, if you have good aim and hit register with RF and anything you like for the small to mid big maps.

i ues the MK14 with ACOG and the CM901 red dot and grenade launcher

MK14 with Acog and Silencer.. a beast of a weapon. would agree with "robbierocket" takes a bit to get used to..

Scar-L (Silencer+Ext Mags)

Type 95 (Silencer+RF)

These are by far my favorite ARs in the game. The Scar-L with Silencer+Ext Mags is an absolute beast.

MK-14 with ACOG and silencer. You rarely lose at range even with the silencer. Only guns that can compete at the longer ranges are the sniper rifles.

this may be a dumb question BUT if the type95 is a 3 shot burst then how does rapid fire help it any? to me it is a beast but i just dont know if rapid fire is what i should be using on it .. i also find that the ump45 with range,rapid fire is pretty good.

M4A1 with red dot and extended mags. I have a class set up with this and SOH, HL, Stalker (all pro) stinger and call it old reliable. When I am playing around with classes and things go to hell in a handbasket old reliable can turn things around pretty quick for me. I put an honest effort into the FAD last prestige (used a token to unlock as soon as create a class opened at level 4) and I HATE that gun!

Acog should never ever be used unless its in CoD 4. Use the AK but equip silencer and xmags. If not then the scar or acr with the same setup.

Sounds stupid and isnt of any help but I like them all situationally.

The ACR is the best suppressed as its damage drop off isnt much.

I love the G36 with Qdraw and stalker.  Its like using a SMG

The AK has great knock down and seems the best for multi kills.

The SCAR is the fastest of the bunch movement wise and rocks on smaller maps and bigger ones.

The M4 is also a really solid gun.  Low recoil, good silenced.

The next tier to me are the harder to use ones with higher rewards like the MK14, T95, and even M16. 

There really isnt a "best" AR to me.

Prefer the ACR or CM901.  Really hard to rationalize not using a silencer.

Depending on how I feel, I will use red dot sight or something like grenade

laucher or shotgun for challenges. Can not freakin stand those burst fire

guns.  If I want to burst fire, I will do it manually.

I have to admit that I am a nub though.

M4A1 red dot coz the iron sight is crap and extended mags all the way. Just went 27-0 tdm with it, not much recoil and decent rate of fire with good damage, totally underated weapon probably coz you get it from the off, everyones levelling up for the ACR (Boring)

mk14 with 2 atchamaent is goog with reflex and silence , you need to use from behind because if the other surprise you , you going to have problem.

a good automatic is the scar , acr or cm901 with silencer and extra magsthat going to save you a lot of time trust me .

and the best is the type 95 but i fekk nasty when i kill with it.

but are depending the map for example in bakara or interchange mk14 or the type95.

and the automatic are good for map carbon and other but automatic are good for every map but on long and open map in prefer mk14

i personally prefer the mk14 silencer with a thermal or a red dot or if i dnt have two attachments red dot and breath but my back up is the cm90 wit silencer and extended maggs
