  • The GSI 3S Steel Buffer is designed for eliminating uncomfortable surging noise and maintaining recoil speed while increasing impact.
  • The recoil spring has been designed to locate inside the buffer and comes with 3 different springs, which can be chosen according to user preference or climate changes.  
  • The increased weight of GSI’s 3S Steel Buffer than the original buffer increases impact, but the structural design allows increasing rebound to maintain return speed.
  • 3S Buffer reduces noise, offers smooth operation, and increases impact power.
  • 3S Buffer is made of composite materials that are steel, stainless, and engineering plastic providing optimal operability and balance.
  • The GSI’s 3S is a unique convention from its own engineering efforts to improve airsoft gun operation, it stands for:   Silent – decrease the noise. Smooth – Improve seamless operation, Shockup – Load time will be dramatically increased

  • The 3S Buffer consists of three springs that can be selected according to the user's preference.
    - Silver spring: Soft elastic spring setting is recommended to reflect the decrease in gas vaporization rate in winter.
    - Black Spring: Used for elastic and stable balance sets similar to genuine buffer springs.
    - Bronze Spring: Reflects the full vaporization rate of the magazine in summer, and recommends a hard spring setting to achieve a strong reaction.
