Due to the changes in the 2.0 Renewal build of the game, talking about damage breakpoints isn't very practical anymore because operatives now have their own individual health tiers. This actually makes my job easier now, since there is one barrel attachment that I can recommend with confidence for all weapons that can support it:

The 2511-LB damage barrel is what you want. It adds both range and damage at a modest movement speed penalty.

Just remember to go for headshots whenever possible, especially against Borma.

A weapon's optimal range dictates the distance where damage drop-off begins. Longer ranges allows you to shoot at a farther target before the damage penalty from being out of range kicks in. The best way to accurately determine in-game ranges is by utilizing one of the CBC range finder aim assists on your primary weapon.


These are the only attachments in the game that can raise a weapon's optimal range (+10% range). There is currently no reason to use any damage barrel other than the 2511-LB, as all of the damage barrels share the same movement speed penalty of -5.


All weapons have access to two suppressor variants; the OPS-1S/R4-SP1 (+4 stability, -10% range) and the R4-SP5 (+2 stability, -5% range). Should you use them? It's personal preference. The game has a strong bias toward close quarters encounters, but there will be situations where a longer effective range would come in handy. Choose accordingly.


These attachments increase damage that's dependent on range. This guide[forums.firstassault.nexon.net] gives a more detailed overview regarding the CBCs, but here are the noteworthy points:

• CBC1 has the most applications, especially for weapons with a high optimal range, like Snipers.
  
• CBC2 fits well on weapons with very short optimal range, such as Shotguns.
  
• CBC3 has very limited applications and is probably the safest to skip out on.

Accuracy determines the tightness of your crosshairs; in other words, it affects your first-shot accuracy. If you have precise aim and prefer tap-firing and/or small bursts, then this is something that you will want to raise.

For Submachine Guns in general, raising accuracy to 60 or above can help a lot with tapping accuracy. Assault Rifles are mostly in a good spot already, but raising accuracy to 80 or above can improve accuracy even further.

The AK-47 has the best first-shot accuracy of all of the automatic weapons in the game.

It's important to note that as of 2.0, SMGs and Shotguns have retained their moving accuracy while Assault Rifles are much worse while on the move now.

In short, the higher the stability, the easier it is to spray a weapon. Stability values of 60+ are common in Submachine Guns, which makes them easy to handle under sustained fire. Conversely, achieving stability in the mid to high-50s requires much more effort for Assault Rifles and Machine Guns. Doing so usually involve the use of bipods, which also have the highest penalties for movement speed.

Movement speed penalties are perhaps the most common of penalties seen amongst all of the available attachments in the game. The amount of movement speed that is sufficient is mostly up to personal preferences, but there are some important things to keep in mind when modding.


Your base movement speed is dictated by the weapon you're currently holding, not unlike Counter-Strike and its many variants. Additionally, the base movement speed of each weapon type (Assault Rifles, Submachine Guns, etc.) is shared within its type; for example, an unmodded M4A1 has the same movement speed as an unmodded AK-47. As of 2.0, the operative you choose to play as determines the weapon class you can use, which effectively leads back to weapons influencing your movement speed.

Submachine Guns and Shotguns are generally very speedy, while Machine Guns and Sniper Rifles are among the heaviest in the game. Assault Rifles are somewhere in the middle. Stacking movement speed penalties on Assault Rifles can have a noticeable effect, especially after the -10 threshold.


The game is fairly heavy on client-side hit registration. This means that if you see something on your screen and you hit it, it will register - even if on your opponent's screen, he happened to have already ducked behind cover. Netcode has since improved as of the December 2016 update, but the principle still stands and pre-firing is still something to take in to consideration.

For details on peeker's advantage, refer to this GIF[gfycat.com]; it was made for CS:GO but is relevant for most online shooters today.

Many first-person shooters today employ some variation of this with certain degrees of tuning, but it should be apparent that being too slow can be a disadvantage if you couldn't peek a corner fast enough, or if you weren't speedy enough to run away from incoming fire.

• Use the 2511-LB damage barrel on whatever you can equip them on.
  
• CBC1 is great on Sniper Rifles. CBC2 is great on Shotguns.
  
• Shooting outside of optimal range lowers damage output. Shooting a limb lowers damage output.
  
• Mod for accuracy if you like accurate taps. Mod for stability if you like to spray.
