Who uses ARs?

I like Sor-556 MK2 / KORD 6P67 / NVO-228E And L85A3 but only cause i used it on other games , using AR's on anything apart from assault is pointless though the guns all handle differently on each class its so stupid how they've built the class system to be more " balanced "
Carbines / are the way to go though if u like using the full auto machine guns
cause SMG has weird nerfs same as assault guns on other classes u just wont hit what u aim at most of the time, all the guns are inconsistent  with how u think theyll act in this game

Me. Mostly because I mained them in past titles. I'm very, very slowly crawling my way towards unlocking the L85 at the moment, as it's my favourite. I do think ARs could do with a look though, as they do feel like they're underperforming a little bit to me. I'm far from "good" at Battlefield, but I lose a lot more gunfights than I used to in the older games. 

KORD 6P67 OMG this gun is really bad i am trying my best to use this gun, i have all the attachment unlocked but this gun is really underpowered.  I have the attachment on to make this gun a great killing machine and stable to boot but oh no it doesn't work like the attachment describe. This gun you have to do an assignment for! **bleep** it bad.

But then again after saying that none of the guns and attachments do as described.  More DICE lies.

DICE lie to us to buy the game.

DICE lies about the description of the gun

DICE lied about the description of what the attachment do

My oh my DICE are you all pathological liars?

I personally don't know why I'd pick an AR instead of a Carbine. They seem quite similar in terms of statistics, yet Carbines have some advantages in terms of ADS speed, movement speed and hipfire accuracy. I'm not too sure what ARs are better at, but I'd expect things like slightly better characteristics at medium to long range. Probably something along the lines of more accurate tap/burstfire, less spread build up, etc.

So the bullet damage numbers are woefully underpowered IMO the KORD only does 27 damage headshots at the closest target in the shooting range and body shots of 17 after 25 meters. The thing basically doesn't kill and I don't know in what universe a piece of hot lead going through a persons brain will happen 3-4 times. Sometimes, especially with AR's, I find myself shooting people 6-10 times at only mid range and they just run away. That sometimes will include headshots. And just yesterday I pumped a dude with 7 bullets in the torso from 58 meters with the KORD THEN he started shoot and he hit me with a 4 burst from an SMG and killed me. It's blowing my mind how the damage numbers are either inaccurate or the weapon damage at range and on body parts is too weak.

They should have added the M277 to Assault Rifles instead of Carbines. It's a tweener between Assault Rifle and Battle Rifle/DMR. It has a heavier bullet and a variable scope as default too. It hardly screams carbine. 

They need to rework guns. I think Beta had it best opening weekend, but maybe it was just  . . . people finding out the meta . . . after ADS for AR and LMG was too dang slow and ppl cluing on gun meta / attachment meta ( to make hip fire accurate as ADS), snipers and DMRS worked as advertised. 

I remember beta the AR was meta, the M4 and the HK 416 (in game has diff name), they could drill ppl and spat out 5 bullets fast . . . hit long range, good close range, only beating close in by shotgun.  SMGS was good back then but they didn't do well at longer range. . . . but as of now its SMG's are S tier. Ppl in reddit are complaining LMG's can't suppress snipers, but SMGs you can shoot them dead instead. AR's ADS is slower, less accurate at close, and bloom at distance than SMG hip fire at close range and no bloom at 100 m .  So most ppl are running some type of SMG with all classes. SMG have less dmg drop offs at long range, than any gun, except DMR and Sniper. 

I suck at this game but when I was going engi (I tend to play sig weapons for the class) I noticed I would win way more gun battles than any other class. (even sniper vs counter sniper cuz I suck at sniping and ppl can quick scope head shot)
