  • The GSI spring improves the BB bullet speed of the GBBR airsoft for both KWA LM4 RIS and MAGPUL PTS versions.


  • Both of those versions have the same mechanism, however, there is a difference in the bullet speed due to the tension of the spring of the nozzle.  The GSI spring for the airsoft rifle resolves the issue.
