8% RPM increase.
Increases the rate of fire by increasing recoil forces, but that also makes the recoil higher in general. Reduced suppression.

The Muzzle Booster is a barrel attachment available to all primary and secondary weapons, except integrally suppressed weapons. It is unlocked at 1200 kills, or it can be purchased with credits.


General Information

The Muzzle Booster is a unique attachment. It increases the rate of fire (RoF) of a weapon by 8%. However, this comes with the cost of reduced suppression and increased recoil.

Usage & Tactics

The main use of the Muzzle Booster is to increase the RoF of a weapon. While it might serve a purpose on faster weapons such as the Kriss Vector, it makes more sense to attach it to weapons such as the SCAR-L. These slower firing weapons usually have a high base damage that is counteracted by a slow fire rate. They also often have much more manageable recoil in the first place, oftentimes primarily vertical. This means that the Muzzle Booster, on these weapons, provides a boost to firerate while providing a negligible increase in recoil. Weapons with minimal side-to-side recoil can take full advantage of this attachment, making it a better choice than the Compensator on these weapons.

Pros and Cons


  • Increases RoF by 8%.


  • Increases recoil.
  • Decreases suppression.
  • Decreases hipfire performance.


  • The Muzzle Booster was originally conceived in the Phantom Forces Community Testing Environment. It is part of a growing list of assets returning from the CTE.
  • The design of the Muzzle Booster appears to be that of the booster found on the MG42, a WWII-era German machine gun.
    • The MG3KWS, itself being based on the MG42, features a similar muzzle booster as part of its design.
      • The MG3KWS can attach the Muzzle Booster, but it attaches on the end of the barrel, not the end of the original booster, leading to the two boosters overlapping. The effect of the attachment is unchanged.
