I got M146 CQB and L96 Arctic Wolf for a day and they are awesome!

M146:

Like no recoil
VERY accurate
Good ROF
Absolutley must get if you have nx, no questions asked. It's as unbalanced as the pistol in Halo 1.

Arctic Wolf:

Faster reload
Just looks plain sweet
Seems more accurate
1 hit KO anywhere, silencer does not subtract from power
More accurate
Steadier Aim

IF you get NX, get:

Smiley Skull Mask
Tactical Backpack (if you're not high enough rank for normal advanced backpack)
M146 CQB
L96 arctic wolf

My KDR went up like .5 when I used this.

PS I play completly legit.
