[Top 10] GTA Online Best MK2 Weapons

What's better than a death machine? An enhanced one!

GTA Online has changed in the past few years; the gameplay went from holding up stores and robbing gangsters to fighting heavily armoured robots wielding miniguns. Rockstar knew you would need more firepower for such enemies, which is why they released MKII weapons.

What are MK2 Weapons?

Added with the Gunrunning update, the MKII (short for Mark 2) weapons are updated variations of already existing GTA Online guns. The upgrade allows you to add attachments, unlock camos and liveries, and add custom rounds.

Why are they important?

  • They are significantly better than their standard variations
  • They’re fun to use
  • Fully customizable with visual and performance modifications
  • Allow you to use special rounds like Tracer, Explosive, FMJ, and incendiary rounds.

Today we’ll give you a list of the top 10 MKII weapons available in GTA Online. Read on.


10. Pistol MKII

First on our list is the Pistol MKII, the enhanced variant of the regular Pistol. This gun isn’t the finest on our list, but it’s a must-have.

The MKII variant gives it a good damage bonus (32 per round) and allows you to equip a mounted scope and compensator for better accuracy and recoil control. It basically solves the issues the standard variant had.

What the Pistol MKII excels at:

  • Cheap and reliable: best choice if you’re out of options
  • Classic feeling: it feels realistic when you use it
  • Customizable: mounted scope and compensator, and custom rounds like armour-piercing bullets.

How to get the Pistol MKII:

  • Can be converted from a Pistol at the Weapon Workshop for $73,750.

Pistol MKII details:

  • Description: Balance, simplicity, precision—nothing keeps the peace like an extended barrel in the other guy's mouth.
  • Custom pistol: unlockable skins and attachments
  • Unlockable bullet options: Incendiary, Tracer, Hollow point, and FMJ rounds



  Next is the SMG MKII, based on the real-life MPX. The upgrade gives it a fresh new look, different from the “washed-out” standard design.

The SMG MKII does 25 instead of 22 damage per shot and has a higher fire rate than the already fast SMG MKI. You can use that to your advantage during close-quarter encounters or while shooting from a helicopter or motorcycle.

It is best used against NPCs without armour, and we highly suggest going for headshots. You can apply custom rounds and attachments thanks to the MKII, so build it however you like.

What the SMG MKII excels at:

  • Fire rate: high fire rate, allowing for easy headshots
  • Close-quarter combat is perfect for shredding enemies in tight spaces
  • Clearing NPCs: efficient against low-armour NPCs like gangsters

How to get the SMG MKII:

  • Buy standard variant from Ammu-Nation
  • Upgrade at you Weapon Workshop

  • Price: $85,500 (Workshop conversion)


8. Carbine Rifle MKII

Next is the Carbine Rifle MKII, a good weapon if you’re the type of player who wants a balance between damage, fire rate, and accuracy.

The Carbine Rifle is an elegant piece of weaponry; it sounds nice and shoots even nicer. It has excellent accuracy over distance, which makes for easy headshots. The fire rate is high, so you’ll be landing most of your shots most of the time. Combine the heavy barrel with armour-piercing rounds and see how you shred players at 100 feet.

What the Carbine Rifle MKII excels at:

  • Accuracy at long range: no bullet is wasted
  • High fire rate: perfect for PVP
  • Damage output: it deals massive DPS at 33 points per round.

  • Price: $107,500
  • Unlocks at Rank: 42


7. Marksman Rifle MKII

  The Marksman Rifle MKII looks like an Assault Rifle, but it’s the farthest thing from that. It’s a semi-auto rifle that deals crazy damage at high RPM, making it perfect for PVP.

This beast deals 75 damage per shot, and combined with the wide choice of attachments and liveries and all the good stuff, you can find yourself clearing heists all by yourself.

If you choose to remove the scope, you’ll end up with a semi-auto rifle that kills players almost instantly within close or medium range. It’s an excellent upgrade if long-range combat isn’t your priority.

What the Marksman Rifle MKII excels at:

  • Even more useful for multiple situations: can be fully used for close-quarters combat thanks to the modified scope

  • Price: $149,000 (upgrade price)


6. Pump Shotgun MKII

Up next is a shotgun that is both efficient and satisfying to use: the Pump Shotgun MKII, an upgraded version of GTA’s version of the Remington 870.

While this buckshot pump-action shotgun isn’t the finest in its class, it deals 32 damage per shot over a slightly slow fire rate. Where’s the catch? The MKII upgrade is only available for the Pump Shotgun.

Even though the upgrade gives you access to attachments, allowing for a better tactical advantage, the biggest improvement is access to special ammo. You can equip explosive or incendiary rounds, which let you wreck players, NPCs, vehicles, and pretty much anything that moves.

It’s a must-have, especially the explosive round combination.

  • Damage: best pick for close-range combat
