Assult Rifles
I love the g36e valkyrie because it has good damage, high accuracy and is a great tap firing gun. The m416 CQB on the other hand has next to no recoil, moderate damage and high portability, but has a limited zoom scope on it, the itech. So if you can tap good I would recommended the G36E Valkyrie.
G36E Valkyrie
M416 CQB
But my fav is the M46A2-Srt (fast reload, good damage, good recoil, can use an acog scope, and has 20 more ammo 35/105) But it is retired from permanent edition.
M6A2-SRT
Snipers
A good sniper is the
L96A1 Artic (L9 Stats)
TPG-1 Pro (Good accuracy[hits where the crosshair is aimed] high magnification scope)
DSR-1 Subsonic (Upgraded L96A1 but with integrated silencer I don't always like a silencer)
M107 CQ SE (Double Scope, which is part bad because it doesn't unzoom after you shoot so you have to camp with it, its heavy as mess, its accurate, but has a high sway in the second zoom [scope moves while breathing] )
Out of those I would Prefer the L9 or the Dsr due to I have a tpg-1 pro and I do short shots as in down the hallway in snow valley, camping at a door, or playing in junk flea. But if you play a lot of long maps such as snow valley and want to get those heads that are barely sticking above something, get the M107 and snipe their a.ss in the face. Otherwise just get the tpg-1..
Pistols
For a pistol the
DEagle which is more like a 2 hit kill sniper. But you can't add a scope or a silencer, and it has high spread[the space in between the crosshairs]. Also the
K4SD which has low damage but a fast fire rate and an integrated silencer.
Sub Machine Guns
If you would rather put more bullets in your enemy get the
MP7 MOD(Good damage for a SMG, fast rate of fire, and one of the fastest reloads.)
Machine Guns
Either the
M21E or the
MG36(the MG36 is based off the G36E series and has a scope but the scope is inaccurate, you have a 50/50 chance of hitting something with the scope. Almost the same stats but I find that the M21E has a little less recoil even though nexon says it has more...
Shotguns
As for shotguns the
M4 Super 90 is the way to go, and the only way[last one you can buy]. It has a 2 hit kill in fairly close to medium range, and it is fully automatic meaning hold the mouse down it will keep on shooting...
Basically just check out the wikia on the guns before you buy (click on any of the links ^^^^) and search youtube for combat arms _________ review (fill in the ___ with the gun name)
