The grip helps, but I don't bother wasting a point. I just use it like I use the AN-94: two- and three-round bursts for long distance, spray for CQC. I might try it with select fire later to see how much it reduces the recoil.
The Scar-H is my most used weapon in the game, AND it's my first weapon I got gold in the game.
I disliked MW3 Scar because it wasn't the Scar-H. The Scar-L felt weak to me. Maybe that's just the limited gun nut that I am. Or it could've been my MW2 Scar-H screaming inside that I missed that beauty. I don't know, but I didn't like the Scar-L.
The Scar-H in Black Ops 2 is my go to gun. I just got done winning probably 8 games in a row with it. Which is not common for me.
Scar is freakin sweat. I don't know why people complain so much about recoil, imo it's very manageable. It doesn't spray around, it just has a bit of cosmetic kick. Damage is very high it's just a pleasure to use. Fast reload speed makes it great to use with just suppressor + stock. No need to waste wildcard on fast or extended mag. The one thing i dislike is pretty bad hipfire.
I rediscovered my love for AR's. Got tired of SMG's and i'm rocking AR's and playing a bit smarter. Much more satisfying and consistent playstyle.
