select fire fal
you really can't go wrong with any of these
The usual Msmc,pdw,m27,an-94,fal. are all very good.
But the peacekeeper is on a totally different level.
Pk, silenced, fast mags, QuickDraw. Is a shoo win in FFA.
For Assault: FAL (Select fire+Target Finder) or the MTAR
Sub-Machine: MP7, Scorpiion Evo or MSMC
LMG and Shotguns for me are ok but I dont really like them that much.
In my opinion it is the Hamr but a lot of people don't like the Hamr in multiplayer for me it is easy to kill enemies with it.
It used to be the AK74 as far as the first Black Ops went. In this game, IDK. I'd have to go with the post patch M27; it so closely resembles the MW2 ACR characteristically that it's almost scary.
There is no best gun. There are guns better than others in certain situations, but there is no "best."
Depends on your gamestyle, game mode and map.
On hijacked a smg is better.
On carrier an ar or a lmg can do better because of the longer lines of sights.
In BO my favorite weapon was the M16. Not the best weapon but I did good with it.
In my opinion..
Assault Rifles: M8A1, M27, Type 25, Scar H
Submachine Guns: MP7, Vector
Shotguns: KSG, R870MCS
Sniper Rifles: Ballista, DSR50
My 2 Best gun classes.
Primary: M27 w/quickdraw, fast mag, suppressor
Perk 1: Hardline
Perk 2 : Toughness
Perk 3: Dexterity, Engineer
no Tactical or lethal Grenades
Wildcards: Primary Gunfighter and Perk 3 Greed
My second class has the exact same this just instead of the M27 I use..
The Ballista w/ Ballistics CPU, Variable Zoom, and Dual Band Scope
In my opinion these classes work amazing with me while Im playing, Headquarters, CTF, TDM, and Hardpoint
