Best SMG in MW4: ISO Nightshade, VEL 46 and Every SMG Build

ISO Nightshade is the best SMG in MW4 to build 1st. Live meta boards put it and VEL 46 1st and 2nd in launch week. You own ISO Nightshade at player level 4, the level that opens Create-a-Class.

VEL 46 fires faster, at 952 RPM to 923, and carries 40 rounds to 30. X-58 Nyx sits 3rd on both boards with a built-in suppressor. PPSh-41 and Wz.55 Striga complete the class of 5.

Each build below names all 5 attachments, the perks and the Apex. Other classes: best assault rifle, best sniper and best LMG. The full launch board sits in best MW4 loadouts.

Tiers follow 2 live Multiplayer meta boards in launch week. Both put ISO Nightshade and VEL 46 in their top 2, with X-58 Nyx 3rd.

• ISO Nightshade, S: 923 RPM and 30 rounds, open from player level 4. It balances control, mobility and close-range stopping power.

Damage and time to kill vary by build and range. Fire rate, magazine size and max weapon level are the fixed numbers on each weapon card.

Each table gives 5 attachments, the Pick 3 perks and the equipment. An attachment unlocks once, then opens on every gun that takes it. Launch picks for every class sit in best MW4 loadouts.

Ghost opens at player level 24, Trophy System at 14 and Concussion Grenade at 15. Quick Fix stands in for Ghost and Flash Grenade for Concussion Grenade until then.

ISO Nightshade build and class

This all-round build suits ISO Nightshade from close rooms to mid lanes. It leaves the optic and ammunition slots free for the Apex.

Why it works: the muzzle and underbarrel tame recoil, and the 40 Round Mag adds 10 rounds. Ghost keeps you off enemy UAVs and Portable Radars. Battle Hardened cuts the effect of enemy tacticals.

VEL 46 loadout

This is the fast-push build for VEL 46. It runs with no stock, which keeps that slot open for VEL 46 Snap.

Slot	Pick
Muzzle	XRK Herder 40
Barrel	VB-46 Series 11
Laser	XRK Clutch-LS
Rear grip	V46 R-Skel Grip
Underbarrel	FSS Fireline Grip
Perks	Overkill, Blood Rush, Battle Hardened
Equipment	Frag Grenade, Concussion Grenade, Trophy System
Unlocks	Player level 5 (weapon card: 13)
Max weapon level	60
Apex	VEL 46 Snap: a tactical sling for fast weapon swaps, with Quick Draw under Overkill

Why it works: the laser tightens hip-fire spread and the rear grip sharpens aim down sight speed. Overkill carries a 2nd primary, and Snap adds Quick Draw at weapon level 60.

X-58 Nyx loadout

X-58 Nyx carries an integrated suppressor, so this build leaves the muzzle alone. It suits quiet flanks at close to mid range.

Why it works: the underbarrel steadies recoil and the laser tightens hip-fire spread. Ghost and Ninja keep a quiet gun quiet. X-58 Void blocks the barrel and ammunition slots, so the LX3-V comes off when you equip it.

PPSh-41 loadout

PPSh-41 takes a fire mod where other SMGs take a rear grip or ammunition. This build is for holding close rooms and objectives.

Slot	Pick
Muzzle	FTAC Silent Recon
Barrel	Hanbit RDR-Tiger 50-XL
Magazine	53 Round Mag
Laser	Schlager Visiv-5
Fire mod	7.62 Tokarev Frangible
Perks	Ghost, Blood Rush, Battle Hardened
Equipment	Frag Grenade, Concussion Grenade, Trophy System
Unlocks	Player level 30 (weapon card: 27)
Max weapon level	62
Apex	PPSh-41 Ember: an underbarrel that fires a burst of incendiary rounds for area control

Why it works: the muzzle refines shot control and the barrel stretches damage range. PPSh-41 Ember blocks the barrel, underbarrel and magazine slots, so it replaces the Hanbit barrel and the 53 Round Mag.

Wz.55 Striga loadout

Wz.55 Striga has the best mobility and recoil control in the class. This build stretches its range and lifts the magazine from 25 to 35 rounds.

Why it works: the build uses no optic, stock or underbarrel, the 3 slots Rampage blocks. At weapon level 60 the akimbo frame adds on top with no change to the build.

SMGs win the close fights that come quickly. Small maps and respawn objective modes serve those fights all match long.

SMG	Range	Best use
ISO Nightshade	Close, all-round	Any map and any mode
VEL 46	Close	Fast pushes and Overkill classes
X-58 Nyx	Close to mid	Quiet flanks and objective play
PPSh-41	Close	Holding rooms and points
Wz.55 Striga	Close	Mobile flanks, akimbo at max level

Hardpoint, Domination and Kill Confirmed keep fights close and constant. PPSh-41 and its 71-round drum suit long Hardpoint holds.

VEL 46 shines beside a long-range primary through Overkill. With VEL 46 Snap at max level, Quick Draw speeds up every swap.

Wz.55 Striga hides enemy skulls on kills from the start, and X-58 Nyx does it with X-58 Void. Both keep a flank quiet on the enemy minimap.

DMZ grants weapon XP too, so an SMG you carry there keeps leveling.

• Play Kill Confirmed, Hardpoint and Domination. Respawns keep the close fights coming.
• Run a Double Weapon XP Token from a new gun's 1st match. Token rules and dates: MW4 double XP.
• Level ISO Nightshade 1st. Each attachment unlocks once, and a level that would repeat an owned attachment is skipped with a Bonus Level Up.
• Every SMG after that climbs faster, since the builds share muzzles, grips and lasers.
• DMZ grants weapon XP too. Unlock and max levels for all 33 guns: MW4 weapons list.

Weapon leveling takes your SMGs to max level on your login. Each Apex opens at the end, from 1 gun to all 5.

8 Military camos come from weapon levels, then 3 Special camos follow on each SMG. Gold asks for all of them, then 15 eliminations in 1 Multiplayer match.

Platinum asks for Gold on all 5 SMGs, then kills from behind. Harmonic Break asks for Platinum on all 33 weapons, then an SMG hipfire challenge.

Divergence comes with 33 Harmonic Break challenges and opens Mercurial Drift, the 1st Multiplayer mastery camo. Full ladder: MW4 mastery camos.

The Mercurial Drift camo service runs it on your login: every gun from zero to Divergence, then Mercurial Drift.
