After patch 1.4 the scar was completely useless, huge random recoil with all fire mode, now at least is playable at close-mid range!
You did a good job trying to counteract the recoil, try also to add left right movements with your mouse!
Becoz this is level of idiots in this community..
Scar+laser+AutoArmor have pretty much ruined the game in the first place, so there are alot of ppl raging or trolling because of that. Don't take it personally
