The M-96 Mattock is an assault rifle in Mass Effect 2, Mass Effect 3, and Mass Effect: Andromeda.

Mass Effect 2


Medium-range, semi-automatic rifle effective against armor, shields, and barriers. Upgrades the Avenger assault rifle.

The Mattock is a semi-automatic hybrid weapon with an assault rifle's low heat production and a sniper rifle's punch. Though it does not have a sniper rifle's precision scope, marksmen favor its increased power over that of an assault rifle to bring down hardened targets. Its lack of a full-auto setting is advertised as a feature rather than a shortcoming since it curbs a soldier's tendency to spray inaccurate fire under stress.


Available through purchase of the Firepower Pack DLC. An e-mail from the Illusive Man appears if the weapon was obtained in this manner.

Mattock Heavy Rifle

Miranda has been working with EDI on crunching battle telemetry numbers, and EDI had an interesting thought. She suggested we may be overlooking older, proven technologies in an effort to provide you with the state of art. Normally I wouldn't give much credence to the idea, but when an AI criticizes you for loving high-tech, it gives one pause to consider.

With that in mind, I delivered a few heavy rifles, the Mattocks, to the Normandy. They've been modified for thermal clips, but the rest of the rifle should be the old, reliable gun that colonist militias have been using for decades. Good hunting.

In the Legendary Edition, it may be purchased from Kenn's Salvage on Omega.

Squad Use

This weapon can be used by Garrus, Grunt, Legion, Samara/Morinth, and Zaeed.

Player Notes

  • The M-96 Mattock fills a tactical role similar to that of the M-15 Vindicator or M-97 Viper, functioning as a high accuracy semi-automatic designated marksman rifle .
  • The Mattock has a fairly low ammunition reserve, so good ammo management is important when deciding where it's safe to rely heavily on this weapon.
  • Charging a lone enemy and rapidly unloading most of the clip at close range with an ammo power is an effective assassination tactic for the Vanguard as long as the target dies and Shepard is able to get back into cover afterwards.
  • This weapon shines in the hands of the Soldier as its unique rate of fire being "as fast as you can pull the trigger" makes it ideal to use during Adrenaline Rush. An entire magazine can be emptied during the course of one Adrenaline Rush, doing extreme damage to one or many targets before the effect wears off. This is especially true if landing headshots during Heightened Adrenaline Rush.
  • A headshot on an unprotected opponent may cause them to stagger and jerk their head backwards, potentially spoiling Shepard's aim. An excellent way to compensate for this is to fire the Mattock twice in rapid succession, resulting in two direct hits to the target's head before it moves.
  • The Mattock works well with Cryo Ammo as it can reliably trigger the freezing effect with a single shot.

Mass Effect 3


Medium-range, semi-automatic rifle. The Mattock is a hybrid weapon with an assault rifle's low heat production and a sniper rifle's punch. Marksmen favor its increased power over that of an assault rifle to bring down hardened targets. Its lack of a full-auto setting is advertised as a feature rather than a shortcoming as it curbs a soldier's tendency to spray inaccurate fire under stress.



The M-96 Mattock can be found during the mission Grissom Academy: Emergency Evacuation, on a couch before reaching Seanne Bellarmine. A second upgrade can sometimes be found in the security room unlocked by David Archer, if he was rescued in Overlord. It is also purchasable from Kassa Fabrication post-mission if it was missed.


Weapons are randomly rewarded through purchases of item packs. The M-96 Mattock is categorized as uncommon.

Player Notes

  • The Mattock's main advantage is its highly accurate and damaging semi-automatic fire, making it very useful for pinpoint (headshot) shooting at medium to long range where it can neutralize most enemies with less than one clip.
  • When equipped with an Assault Rifle Precision Scope, it is versatile enough to serve as a main or even sole weapon under almost any circumstances.
  • Although the Mattock is a semi-automatic rifle, it has very little delay between shots, allowing it to be fired almost as quickly as the user can pull the trigger.
  • While the Mattock does sufficient damage to kill in one shot, a squad of close-range enemies can cause real problems due to its low capacity and its semi-automatic nature. Thus it is advisable to carry an alternative weapon such as a submachine gun to keep the low weight and offset your close-range shortcomings. Using Armor-Piercing Ammo so that a single round goes through multiple targets can help with close quarters combat.

  • One issue with the Mattock is its relatively high weight. Despite it being lower than the M-76 Revenant, it is still quite heavy. This can make it difficult for those who need to use powers frequently to be combat effective. Despite this, it is lighter than an M-13 Raptor sniper rifle, at the cost of accuracy and rate of fire. The Raptor also has a scope equipped by default, freeing up space for another weapon mod. Players may wish to take these factors into consideration when choosing either rifle, based on their playing style.
  • Higher weapon levels, combined with certain power evolutions on Krogan Soldiers, Krogan Sentinels and Drell Vanguards, can still give you +200% power recharge, which makes it a great "lightweight" choice for those classes.
  • The Mattock can use an Assault Rifle High-Velocity Barrel and/or a Armor-Piercing Rounds to drastically increase its effectiveness against certain enemies like Cerberus Guardians, or armor-plated Husks/Cannibals.
  • The Assault Rifle Magazine Upgrade mod is also pretty useful, given the Mattock's high damage but moderate capacity. It can make the Mattock into a very effective assault rifle with a good balance between ammo, damage, range, weight, and accuracy.
  • The Mattock (levels VI+) works very well when paired with a Turian Sentinel who, with the correct power evolutions, can still have a +200% power recharge. This is especially useful against geth, as it allows the player to repeatedly spam Overload (even while wearing Tech Armor) to drain the shields of enemies, and then use the Assault Rifle Precision Scope mod on the Mattock to headshot them repeatedly. It's also a solid choice for the Turian Ghost Infiltrator, who benefits from enormous bonuses to weapon damage and stability, and has an extra 20% assault rifle damage bonus at the end of his Tactical Cloak tree.
  • While the Mattock is primarily a medium range weapon, it can be used effectively at close range if it has an Assault Rifle Magazine Upgrade and if the player has a fast trigger finger. Armor-Piercing Rounds or Drill Rounds help in close quarters by passing through enemies and hitting multiple targets.
  • Adrenaline Rush turns this already powerful weapon into a deadly combat rifle capable of dealing serious damage to even the biggest of enemies. In the 6.8 seconds given, you can easily squeeze off at least 30 rounds, even more if you are good at reload-cancelling and trigger pulling. This allows one to dispose of whole groups of infantry with surprising speed, especially with Assault Rifle Piercing Mod and Assault Rifle Extended Barrel mods combined.

Mass Effect: Andromeda


The M-96 Mattock's increased power is favored by marksmen looking to bring down hardened targets. Its lack of an automatic setting was originally advertised as a feature rather than a shortcoming as it curbs a user's tendency to spray inaccurate fire under stress.


The Mattock suffered an issue that prevented it from reaching its stated rate of fire. Fixing it made the weapon too powerful, so to compensate its damage per round was lowered while its max ammo was increased. However, its last balance update drastically increased its damage as well as its clip size.

  • The Mattock was balanced differently from other assault rifles. The rifle does very high damage per shot, but offsets this by significantly limiting the ammo available, forcing players to make each shot count.[1]
  • A Mattock is a hand tool similar to a pickaxe that was often used by infantry as a form of improvised weapon during the Middle Ages.
  • Like the M-15 Vindicator, the Mattock fires on full-auto during cutscenes despite being semi-automatic.
  • Like the Vindicator and Avenger, the Mattock's integrated scope was removed from its model in Mass Effect 3, likely to avoid looking redundant if the player adds a scope mod. In game, this does not affect its (unmodded) accuracy.
  • There is a bug in which Grunt will not fire the Mattock. This can be corrected by swapping his weapon to shotguns and then back to assault rifles.
  • The M-55 Argus, the Cerberus Harrier and L-89 Halberd are variants of the Mattock.
  • Mass Effect: Infiltrator features a fully automatic version of the rifle known as the M-96 Mattock Auto, complete with a yellow and white Cerberus finish that is identical with other Cerberus weapons. The weapon was later added to Mass Effect 3 as the Cerberus Harrier. Unlike its Mass Effect 3 counterpart, the M-96 Mattock Auto in the mobile game will generate heat instead of using thermal clips.
