The guns above used in Hardcore are superb. Little to no recoil, Most of the Support Class guns take 2 bullets to kill a person, and the rest take 4-5 bullets but are still quick enough to kill the other person before they kill you.
Medic: Famas - Supressor, Foregrip, Holo(IRNV in night maps)
Support: M249 - Extended mag, Bipod, Holo
Engineer: Scar-H - Supressor, Foregrip, Holo(IRNV in night maps)
Recon: L96 - Flash Supressor, Straight pull, Rifle Scope 8x(Hate the Ballistic) ---- I use IRNV sometimes in the night maps
I ONLY play Hardcore.. I HATE killcam and the low damage rate
Assault-AEK971, 2nd fastest at 900rpm,Still not the best horizontal recoil, but very nice, fast groupings. Foregrip is a must though,
+ fire successive bursts at nearly 1200RPM.The biggest problem seems to be the vertical recoil.
FAMAS- Fastest TTK, But worst recoil mid-long range , Foregrip is a must. Best at Close Quarters, People named it the Noob Ripper Don't Ask me
Holographic, Foregrip, Silencer for Both, sometimes AEK971 Heavy Barrel for burst fire burst reaching (1000-1200RPM)

Engineer: SCAR-H with RDS, Foregrip and Heavy Barrel
Support: PKP Pecheneg (i use it only because of heavy .cal) with RDS, Extended Mag and Foregrip
Recon: SV98 with Ballistic or other lower range scopes (depending on size of the map), Straight Pull Bolt and... nothing.
