I'm at Level 32 and had experience with various guns but DICE has made every weapon balanced but there are some that stand out for certain catagories ( Note these are my opinions and you might have different taste in weaponry than I do).
Assault Rifles
#1 FN2000:This gun is the most deadly CQB and Mid range weapon ever and is my favorite assault rifle of all time. I've used to use the M416 but this gun is ultimate because of its higher ROF and RPM than the M416 + it has larger caliber rounds! I've also "sniped" with this weapon on single fire and gets headshots within 3-8 shots. Best loadout for this would be Holographic sight with *Heavy Barrel* because it reduces the recoil.
CONS: This runs out of rounds rapidly while shooting in long bursts from 3-5 sec you'll run out and have to reload. BUT thats why I carry a G18 full auto pistol on hand to switch to devaste my opponents
#2 M416: Deadly at Mid Range and Long range combat and a weaker than the FN2000 ^^^ It's ROF is quick and RPM is decent. Shooting from long range with this gun works quite fine to since it has many firing modes. Holographic sight, foregrip, and a heavy barrel suit this gun great for my preference but keep a strong pistol on hand when you run out of bullets in a magazine.
CONS: Bullet Caliber and ammo shortage
#3 M16 A3: Is a great all around weapon and has great caliber size. Sadly it has no burst fire but thats minor. It's great at all ranges but at its best mid quarters.
CONS: No burst fire and I kind of hate the vertical recoil.
#4 FAMAS: Its the best long range rifle out there with its great ROF and RPM, its a beast from a far with ACOG. It has all the firing modes so its best suited for any situation.
CONS: Iron sights are absolutly horrile to me and the ballistic scope ( I don't snipe that much so maybe thats why).
Submachine Guns
#1 SG553: It is a great overall submachine gun because it has the very least recoil I've seen on a gun and is even more accurate with a Holographic sight, Foregrip, and Heavy barrel to make it DEAD on accurate. It's more faster than the SCAR H and UMP 45 making exceptional for close quarters and mid range combat.
CONS: Long range kills plausible unless you use single fire.
#2 UMP 45: Many people think its over powered but its absolutly bad at long range unless you have the right scope but still requires some short bursts to kill. Mid range is where everybody complains and short range is expected to be powerful.
CONS: Long Range kills plausible
#3 Scar H: Overall a good all round submachine with its great bullet caliber and firing modes. Its good from all ranges but more exceptional at mid range.
CONS: I don't like the magazine size but thats just me.
