15% muzzle velocity loss.
30 stud detection radius.
A medium Russian suppressor. Compared to the PBS-1, it provides slightly more range for a small maximum damage penalty. It provides decent sound masking.

Statistic modification

*Need update

  • Hides muzzle flash, reduces weapon noise by 15%
  • Reveal range: 30 studs
  • Muzzle velocity: -15%
  • Maximum damage: -2%

Tactics & Usage

This suppressor stands between the initial suppressor and the R2 suppressor. It is good for close range engagement with less damage compromise than the initial suppressor, although not enough to match the R2 suppressor at further range. Recommended for PDW and assault rifles.

Trivia

General trivia
  • Suppressors, by themselves, do not actually slow down bullets in real life - in fact, they tend to increase bullet velocity slightly. Rather, this mechanic is probably to reflect the fact that suppressors are usually used with subsonic ammunition. Standard ammunition makes a distinctive crack due to it going at supersonic velocities, which would ruin the point of having the firing sound of the weapon decreased, however, in combat conditions, with a sniper rifle, it may be difficult to pinpoint the exact location of the sniper with a suppressor, unless the supersonic ammunition reveals the location.
    • Certain weapons used this trope by virtue of their bullets being so slow that the suppressor improved the bullet velocity. However, in Update 4.3.0 to present, the suppressors reduce bullet velocity using percentages instead of fixed values, eliminating this exploit.
    • Another quirk of suppressors is that they increase the cycling speed of many of the weapons they are attached to due to gas blowback. Manufacturers tend to try and avoid this as while it may increase the firing rate of weapons and thus their firepower, unintended increases in cycling speed can seriously damage guns not designed to take advantage of or withstand such side effects.
  • Shotgun slugs have priority over the suppressor's velocity reduction, which means every slug will still travel 1800 suds/s regardless of barrel attachment.
    • This make shotguns particularly effective with suppressors when taken for mid range sniping.
  • The Stevens DB and Sawed Off cannot attach suppressors, as the double barrel would be troublesome to suppress, but still possible. Along with this, no revolver can attach a suppressor either, due to the structure of a revolver not being suited that way.
    • The only exception would be the Nagant M1895 (not in-game), as this revolver has a gas seal mechanism that allowed it to be suppressed properly. However, there are other silent revolvers as well, such as the OTs-38 Stechkin Silent Revolver (also not in-game). Unlike the Nagant revolver, they involve using silent ammunition, not external means, and as such, they do not count.
      • Integrally Suppressed Weapons cannot attach barrel attachments, due to the barrel design not being able to accept such an attachment. However, manufacturers can make their suppressors with built in muzzle devices such as muzzle brakes and compensators.
