Rainbow Six Siege Attachments:
Barrels Guide

Learn about barrels choices available in Rainbow Six Siege! 


Our R6 barrels guide will use certain terms to describe the benefits of different attachments.
Therefore, let’s start with going through the list of terms that we will use going forward:
  • Muzzle climb– Vertical recoil of the weapon
  • Diamond size – Every shot has a diamond-shaped area for the next bullet’s recoil. Some barrels reduce the size of that diamond.
  • Centering time – time needed after shot for crosshair to return to the original position
  • Muzzle flash – a flash from a muzzle of your weapon that can decrease visibility
  • Smoke trails – firing weapons leaves visible white smoke lines. Those lines indicate where the shot came from.
  • Threat indicators – white arc on players’ screens when they get shot at. Indicates direction from which the damage is coming from.
Additionally, since barrel attachments are quite tightly connected to the topic of recoil in Rainbow Six Siege, we recommend watching this video of Zironic:



Rainbow Six Siege Flash Hider Barrel attachment

Flash Hider

Since Y6S2 this barrel attachment has simplified impact on the recoil.

Flash hider decreases the vertical recoil – both the speed and strength of the climb.

Rainbow Six Siege Barrel attachment - Compensator


Similar to flash hider, the compensator’s impact on recoil has been streamlined.
Currently, this attachment lowers the horizontal recoil of guns.

Muzzle Brake

  • Reduces first shot muzzle rise by 45%
  • Reduces centering time by 45%
Great barrel for weapons with a massive kick on a first shot (Buck’s C8) and semi-automatic weapons – DMRs and Pistols.
Rainbow Six Siege Barrels Attachments - Suppressor


  • Eliminates Smoke Trails
  • Removes Threat Indicators
  • Removes Muzzle Flash
  • Lowers noise generated by the shot
  • Reduces damage per bullet by 15%
  • Has no impact on recoil
Gunshots are still audible, but harder to locate the direction from which they are coming from. The suppressor is designed with stealth in mind.
The damage reduction is the main reason this barrel is not too famous.
Rainbow Six Siege Barrels Attachments - Extended Barrel

Extended Barrel

  • Increases damage on long distances (above 25m) by 15-20%
  • Has no impact on recoil
An extended barrel is the least popular barrel attachment in Rainbow Six Siege. An increase in damage output on the long-range is insignificant, in most weapons cases.

Below recommendations are our own preferences when it comes to equipping barrel attachments to certain guns.
Some of them will be obvious, but others are highly subjective.

If you disagree with our suggestions and feel better by using other R6 barrels on your guns, then great – stick to it.
But we suggest that you at least test alternatives on your main operators. Preference is acquired, hence it usually requires testing of various options beforehand.
