Attachments are devices attached to a weapon to enhance a certain aspect of that weapon. Throughout the Metro system, the player will find many types of guns that are either standard models of the weapon, meaning it has nothing attached to it, or that it will have some sort of attachment on it. In Metro 2033, weapons cannot be customized but can be found with various attachments in the Metro. In Metro: Last Light the attachment options have been widened with customization possible in vendors, as well as a wider range of attachments available. The attachment system is introduced into Metro 2033 in Metro 2033 Redux. In Metro Exodus, customization options have been greatly expanded and they take advantage of the new crafting and modification system, intoduced to the game.

Metro: 2033Edit

ScopesEdit

AK-74 scope

A Kalash with a scope

Some of the guns found in the Metro will have a scope attached to it, which allows the user to engage in long-range combat. However, there are only two levels in Metro 2033 big enough to allow long-distance sniping. Glares and oily thumbprints on the optics obstruct vision in the dark and this problem is made even worse with Night Vision Goggles equipped. Use of scopes is only recommended if the player wants precision. The Tihar and Helsing are practical with scope equipped because of their stealthy nature.

BayonetEdit

Uboinik bayonet 1

A Uboinik with a bayonet

The Bayonet is only available for the Uboinik Automatic Shotgun in Metro 2033. It greatly increases the user's melee damage, and it is quite handy if you do not have time to reload and mutants are very close. It could be handy for stealth kills, though many players will choose silenced weapon or throwing knives instead for sneaky approaches, no ammunition required is the bayonet's biggest advantage. There are no negatives to having this attached to the Uboinik, as it does not slow you down in any way, or restrict view like other attachments. The Bayonet is also featured on NPC versions of the Kalash, Kalash 2012 and the VSV but they are unusable. It was removed from the game in Redux.

SuppressorEdit

ATT supressor

The Suppressor, or more commonly known as a silencer, is an extremely useful attachment for those who prefer a stealthy approach in combat, or for those who need to remain stealthy in some levels. The suppressor allows the user to eliminate hostiles without alerting others of their location. The suppressor can work as a flash hider that eliminates muzzle flash, which can be easily noticed during a firefight. It also reduces recoil of the gun, increasing accuracy, but the bullets are slowed, meaning they inflict less damage on enemies. Some guns are naturally silent like those that use compressed air as a propellant such as the Tihar, Helsing, or the VSV, that has a suppressor built in. However, the Suppressor does not muffle a gun completely, so enemies will become suspicious when firing too close or by missing a shot. The Suppressor is available for:

Laser SightEdit

The Laser Sight is a hugely beneficial attachment on any gun as it increases the user's accuracy and is even more useful in the Ranger difficulties as the HUD is removed and there are no on-screen crosshairs. With this attachment, you can aim without using a scope or iron sight, as a red dot is projected wherever Artyom is aiming. Oddly enough, this cannot be seen by opponents. However, the red dot does not necessarily point exactly where you are shooting while on the move. When shooting stationary, the Laser sight provides better accuracy.

The Laser sight is available for:

Extended BarrelEdit

Revolver barrel 1

In Metro 2033 the Extended Barrel is exclusive to the Revolver and provides a huge improvement over the standard revolver, adding more accuracy to the gun and increasing the range.

Rifle StockEdit

Revolver stock optics silencer 1

The Rifle Stock is another attachment that is also exclusive to the Revolver. It greatly reduces the recoil of the gun and is always seen paired with either a Suppressor or an Extended Barrel. Using this turns the revolver into a small carbine.

Metro: Last Light & Redux Edit

In Metro: Last Light you can find weapons with attachments like Metro 2033, but with enough Military-Grade rounds, you can customize the attachments yourself at the weapon vendors. The prices of these attachments are different between difficulties; the higher difficulty you are playing, the more expensive the attachment costs; with two exceptions in the first and last D6 level, where you can equip and customize weapons for free. (Sparta Base in Metro 2033 Redux also allows Artyom to do the same) If you want, you can get some MGRs back by uninstalling your attachments. 

Reflex SightEdit

ATT collimator
This pre-war sight makes aiming the gun at close and medium range easier, without sacrificing much of the field of view.

— Store description

The reflex sight, or red dot sight, is the cheapest power scope and is available for purchase for 25 MGR (37 on Hardcore). The Reflex sight has no magnification, like the IR sight. It is available right away at all gun kiosks and shops. Most smaller guns (non-heavy weapons) can support a reflex sight. It provides faster short-range target acquisition, but unless combined with the Laser Sight attachment it can make precise shots more difficult since despite its name it does not provide an actual dot, but rather a rounded reticle with no center marker. Adding the Laser Sight makes up for this, with the laser providing the actual "dot" at the center of the reticle. However, it is a cheap sight for early in the game that makes it easier to aim until more powerful scopes become available, and sometimes this is better than iron sight. It has one advantage over the other scopes is that it reduces vision a lot less than they do, so you can see more looking through it. The sight is good for close range combat since you are able to ADS faster any other type of optics. It can be noted that the Reflex sight has very slight night-vision capability. Rather humorously, the in-game Reflex Sight is not based on a Russian design; it is in fact based on an American Sightmark Sure Shot red dot sight. Reflex optic is available in the Exhibition station, however, it is recommended to buy it in Riga station after Artyom gain more MGRs.

Infrared SightEdit

ATT IRNV
A piece of pre-war military tech, this Night Vision sight allows for precisely hitting targets in the dark.

— Store description

The IR sight is a unique sight. Unlike the other sights (that enhance zoom power), the IR scope uses heat signatures to point out enemies in dark locations, it's also very similar to the effect of the night vision goggles. When the NVGs are equipped, the effect of the IR scope is no longer apparent but unlike NVGs, the IR Scope has a clearer sight picture when aiming at distant targets at the expense of a narrow field of view. It is available since the Bolshoi level and onwards at all gun shops and kiosks much like the reflex sight. Later in the game, when you are affected by the Darkness, the IR scope will still work for some reason, unlike the flashlight or NVG, but its limited field of view makes it impractical compared to lighter; it does have one advantage, enemies never notice the IR scope while the player is hidden. Which make this attachment good for subtle players. It is recommended to attach at least one gun with NVG scope that you can navigate through the dark without being seen, while the NVG goggles are a better choice for this task, the NVG scope is available much earlier and no charging required, as it never runs out of power source. Like Laser sight and Reflex sight. It costs 35 MGR (52 on Hardcore). In Metro 2033 Redux, IR optic is available in the Armory station and onwards.

2x Optical SightEdit

LaserSightBastard

A fully upgraded Bastard. Equipped with a red laser sight and a 2x scope.

The pre-war, 2x Sight facilitates weapon aiming at medium range but limits the field of view, making it hard to use in the confines of tunnels.

— Store description

The 2x sight acts like the reflex sight but the zoom is much higher. It is the second most powerful zoom sight with the 4x sight being the first. It can be purchased in Bandit level and onwards. It costs 45 MGR (67 on Hardcore). It can be equipped by most weapons excluding all shotguns and the four sniper rifles, which have a 4x Optical sight instead. For players with low-performance PC, using this attachment could pose a problem, as lag may occur while zoomed in. The scope itself is based on a Russian PO 3.5x21. In Metro 2033 Redux, 2x Optic can be purchased for Tihar, instead of the standard 2x sight, the player will get the 3-aperture optic found on the original Tihar. 2x Optic is available in Market station and onwards.

SuppressorEdit

ATT supressor

The Suppressor, or more commonly known as a silencer, is an extremely useful attachment for those who prefer a stealthy approach in combat, or for those who need to remain stealthy in some levels. The suppressor allows the user to eliminate hostiles without alerting others of their location or just used to blow out lights. It also reduces the recoil of the gun increasing accuracy, but the bullets are slowed, meaning they inflict less damage on enemies. Some guns are naturally silent such as the Tihar or Helsing, that use compressed air as a propellant. Unlike in Metro 2033, the VSV in Last Light now has a removable suppressor, but the weapon's usefulness is greatly reduced without it. Also, the Clapper has an integral suppressor, thus making purchasing one unnecessary. However, the suppressor does not muffle a gun completely, so enemies will become suspicious when firing too close or by missing a shot. The suppressor also removes the muzzle flash for some weapons, making the user harder to detect. With all these stealth-related benefits, the suppressor is a recommended choice for at least one gun, although it costs 60 MGR on Hardcore. In Metro 2033 Redux, Suppressor is available in Exhibition station and onwards.

The suppressor is available for:

Laser SightEdit

The Laser Sight is a hugely beneficial attachment on any gun as it increases the user's accuracy and is even more useful in the Ranger difficulties as the HUD is removed and there are no on-screen crosshairs. With this attachment, you can aim without using a scope or iron sight, as a red laser beam is projected wherever Artyom is aiming. In Last Light the lighter can be used with a weapon equipped, so adding a laser sight to the weapon can greatly improve accuracy while doing so. Oddly enough, this cannot be seen by opponents. It is best used together with the red dot sight/IR Scope for the best accuracy. The Laser sight is relatively cheap compared to other attachments, 22 MGRs on Hardcore, and most guns in-game can attach this mod.

The Laser sight is available for:

Extended BarrelEdit

Revolver barrel 1

The Extended barrel makes a reappearance in Metro: Last Light, but instead of being exclusive for the revolver, it now can be attached to shotguns, pistols, and a few other weapons Artyom comes across. It again reduces recoil and increases accuracy, though at the cost of making pistols harder to wield. However, this apparent disadvantage does not appear to have any impact on gameplay. The Extended Barrel is a recommended attachment for the shotgun as it greatly reduces pellet spread, making it more accurate up close as well as increasing effective range. However, it is not necessary to install this while you are low on MGR, shotguns without extended barrel still have a moderate range. This attachment costs 67 MGRs on Hardcore.

The extended barrel is available for:

Grips and stocksEdit

Revolver stock optics silencer 1

Most secondary weapons can be fitted with some sort of stock or grip, like the Revolver with rifle stock in the previous game. They still increase accuracy and decrease recoil, greatly improving pistols. With the Bastard, it improves its primary weakness of recoil and puts the Bastard on equal footing with other assault rifles like the Kalash. A Lolife with a rifle stock, suppressor and extended magazines can be found in the locker in Facility and is a powerful weapon so early in the game. Pistols with the full stock and foregrips become powerful carbines, especially if other attachments are added. The Duplet also has access to a grip and stock, greatly reducing the normally terrible recoil. The Stock cost 60 MGRs on Hardcore.

The rifle stock is available for:

4x SightEdit

The 4x sight is similar to the 2x sight, except that it (obviously) is twice as powerful. It is only useful for long-range sniping, so can only be fitted to sniper rifles, as the shrink view may hamper quick aiming. Despite doubled the magnification, it is visually similar to the 2x sight. It costs 67 MGRs on Hardcore.

The 4x sight is available for:

Extended MagazineEdit

The extended magazine increases the ammunition capacity of guns (meaning you have to reload less), and thus is handy in a fight, especially with fast mutants like Nosalis. They come either as larger box magazines or drum magazines. The amount of capacity they increase varies per weapon.

The extended magazine is available for:

  • Kalash (from 30 to 45 rounds)
  • Saiga (from 10 to 20 rounds)
  • AKS-74U (from 30 to 45 rounds)
  • RPK (from 45 to 100 rounds)
  • Abzats (from 20 to 40 rounds)
  • Lolife (from 8 to 20 rounds)
  • Valve (from 5 to 10 rounds)
  • Preved (from 1 to 5 rounds)


The quad barrel attachment for the Duplet technically increases capacity from 2 to 4 rounds, but two shells are fired at once with the primary trigger, and four with the secondary, meaning you will still have to reload as often as before the upgrade and the ammo reserve will chew up faster - but it will deliver some serious firepower at close range.

Airtight ValveEdit

The airtight valve is a very useful attachment for pneumatic weapons. If you can spare the MGRs, then it is a must. The valve stops the gradual leak of pressure from pneumatic weapons, meaning they will only lose pressure from firing rounds. This reduces the number of times you have to pump the weapon, as well as meaning you can always be certain the weapon will fire, as long as you pump them after every fight. This also help turning them from long range stealth weapons into ones that can cope with close range attacks.

The airtight valve is available for:

Flash SuppressorEdit

The flash suppressor is only available on snipers and the Abzats shotgun. The suppressor reduces recoil, improves accuracy and reduces the flash of the weapon firing, meaning you will not be blinded in small tunnels, and enemies will not be able to see you fire it. However, it does not reduce the sound of the weapon, so enemies will still fire in your general direction. With no obvious drawbacks, it is a must for all long range snipers.  You can only purchase this upgrade in Depot, and it costs 60 MGRs on Hardcore. A free chance to get this upgrade is the armory just before the battle for D6.

The flash suppressor is available for:

Heat SinkEdit

The Heat Sink is only available for the Bastard and reduces its primary weakness, overheating, by venting excess heat via longitudinal metal fins and reducing the need to manually vent the weapon after prolonged firing. This upgrade allows the player to fire Bastard automatically longer before it overheats. Heat Sinks cannot be bought, but instead, are found (only) pre-fitted on various Bastards scattered throughout the environment.

The heat sink is available for:

Autofire AdapterEdit

The Autofire Adapter is a device allowing normally semi-automatic weapons to fire fully automatically, obviously increasing rate of fire, but also increasing recoil, making it harder to control. In the Sniper team level, the Lolife you equipped already has this attachment. This attachment is pretty expensive, 90 MGRs on Hardcore.

The autofire adapter is available for:

Metro ExodusEdit

The attachment system has been completely reworked and expanded in Metro Exodus. The player is now able to not only attach for example different sights or a bigger magazine to a weapon, but entire integral parts of the weapon, like its barrel, inner mechanism or stock can now be replaced with a different assembly, sometimes alternating the function of the weapon dramatically, like turning it from bolt-action into semi-automatic, or turning it into a completely different weapon class (for example, the Bastard can now essentially become a light machine gun, the Revolver can be made into an effective sniper rifle, and the Tikhar can be turned into a railgun). Therefore, it's more accurate to refer to the attachments as "upgrades" or "customization parts".

Most weapons in the game have five different parts that can be modified: Grip/Stock, Barrel/Mechanism, Sight, Magazine and Gadget. The only exceptions are the Ashot, which doesn't have a Magazine upgrade slot, as its ammo capacity is determined by the upgrade installed in the Barrel slot, and the Gatling Gun, which currently doesn't have any upgrades available to it and it only has two upgrade slots.

Upgrade Stock Icon
Grip/Stock upgrades are available to all weapons except the Gatling Gun. Most weapon start with crudely made stocks, usually referred to as Light stocks, which claim to be suited for dynamic firefights because of their low weight. Heavier stocks affect the weapon swap speed, which can be detrimental in close quarters combat, such as when being swarmed by mutants. However, upgrading the stock is always a good idea, as it provides considerable boost to Stability, making the recoil of the weapon easier to control, which arguably makes up for the slower draw speed of the weapon. Some weapons share Stock upgrades together, for example, the stocks available for Kalash can also be used on the Bulldog and the Shambler.


Upgrade Barrel Icon
Barrel upgrades can be installed on most weapons, except the pneumatic/exotic weapons, where its firing mechanism can be upgraded instead (see below). Longer barrel usually increases accuracy and damage of the gun, but decreases its stability, making it more suitable at longer range and slow, precise engagements, while being less effective at close range. However, the negative impact on stability can usually be easily balanced out by upgrading the Stock. Some weapons can also mount a suppressor, which negatively impacts the damage of the gun, but makes it harder for enemies to spot the player when firing. Still, pneumatic weapons or throwing knives are the better option if one wants to remain completely unnoticed, as at close range, even suppressed weapon shots will be noticed by the enemy.


Upgrade Mechanism Icon
Mechanism upgrades are present on the Tikhar and the Helsing instead of Barrel upgrades, as these weapons either don't have a barrel at all, or it wouldn't serve any purpose to upgrade it, because of the way the gun works. Tikhar's pneumatic system can be upgraded to become airtight, to automatically refill, or it can be swapped out completely for a railgun assembly, effectively turning the weapon into the Volt Driver. Helsing's crossbow limbs can be upgraded to provide more kinetic energy to the bolt, increasing its damage and range, or it can be replaced with a pneumatic system with increased rate of fire.


Upgrade Sight Icon
Various Sights determine the method of target acquisition. By default, all weapons are fitted with iron sights and all weapons can also equip a Reflex sight or an NV scope, which allows the player to effectively aim in the dark, while being mostly useless during daytime. The last Sight upgrade can either be a 4x scope (for example for the Kalash or the Helsing), a 6x sniper scope (Valve, Bulldog and Tikhar) or a closed reflex sight for the Bastard and shotguns - weapons that are intended to be used at long range usually get a more powerful scope than close-range weapons.


Upgrade Mag Icon
Magazine upgrades have impact on how many rounds the player can fire before reloading. Larger magazines usually decrease weapon's stability and sometimes take longer to reload (for example, the box magazine available for the Shambler). Some magazines (like the Bastard's box magazine) are so large, that the Ammo vest upgrade is required to effectively use them, as the ammo capacity can exceed the total amount of rounds the player can carry by default. The Revolver and the Valve have unique Magazine upgrades available to them, which not only increase the ammo capacity, but also turn the weapon from single-action/bolt-action to double-action/semi-auto, increasing their rate of fire noticeably.


Upgrade Gadget Icon
Gadgets are various accessories that can be mounted on the underside/side of the weapon. Currently, these include various kinds of laser sights, which make it easier to aim without looking through the sights/scope, as they replace the default crosshair (which doesn't have a center point) with a laser dot that slows more clearly where exactly the gun is pointing at. It is possible that future DLCs will include more Gadgets with different functions, as this is probably the most customizable upgrade slot, as many different gadgets can be mounted to weapons in real life (flaslights, grenade launchers, underbarrel shotguns, bayonets, ...)

Visit each specific weapon's wiki page for the list of upgrades available to it.

TriviaEdit

GeneralEdit

  • The Revolver has a gas seal system similar to the Nagant revolver, allowing it to be suppressed.
  • The Laser sight is slightly different between games, in 2033, only a red dot can be seen, in Last Light and Redux version, however, you can see the laser beam.

Metro 2033Edit

  • The model of the scope used by all weapons except the Tihar is the Russian PK-AV Scope.
  • The Tihar is the only weapon to use a unique scope. It uses a series of three aperture sights.
  • In the Metro 2033 Launch Trailer as well as in the Prologue cutscene, Artyom is seen with a fully upgraded Kalash 2012 with a Bayonet, but in-game only the Bayonet-attached Automatic Shotgun is available to Artyom.

Metro Last LightEdit

  • The Bayonet attachment is not available in Metro: Last Light, as melee mechanics are changed.
  • The Laser sight is normally red in color, sometimes green laser sight can be seen, usually used by friendly NPCs like Rangers. Unique green laser sight mounted Kalash can be found in Red Square level in Last Light, however.
  • The red dot sight seen in Metro: Last Light resembles the BSA Multi Dot Sight instead of the much more likely Russian-made Kobra, PK-ASV, PK-04 or some other equivalent. The many specialized shops in Moscow probably had this particular model or similar replicas in stock before the bombs fell. A few might even be scavenged from airsoft guns, given the popularity of the attachment in airsoft.
  • The scope in Metro: Last Light resembles the Russian PK-A red dot optic, with chevron style reticle similar to the one found on a PSO-1 optic.
  • The 4X optic is based on PSO-1 scope, first used by Dragunov SVD.
  • The Flash Suppressor seems to be based on the arrowhead muzzle break that normally used by Anti-Materiel rifles like Barrett M82 or the French PGM Hecate II.

Metro ExodusEdit

  • There are 8 weapons with 20 different parts/upgrades (5 slots with 4 upgrades each), one weapon, the Ashot, with 16 upgrades (4 slots with 4 upgrades) and the Gatling Gun, which currently has no upgrades. Using the rules of combinatorics, it is possible to calculate that each weapon with 20 upgrades can have 1024 different combinations of upgrades/parts, the Ashot can have 256 combinations and the Gatling Gun currently has only one. This brings the total amount of unique weapons that can theoretically be encountered to 8449, far greater than in any of the previous games. However, much less variants are used by NPCs, as the higher-tier upgrades are usually very rare and only found in one or two examples throughout the entire game.
  • The Reflex sight uses a different model compared to previous games, which now seems custom-made, but the description reamains the same, still claiming that it is a pre-war piece of equipment, which is no longer true.
