It is held in with a spring pin.
  

  INSTALLATION AND MAINTENANCE:

  The polymer bumper goes towards the rear of the firearm and the weight mass with the o-ring goes towards the bolt carrier.

  • • The SRS can be installed with or without the buffer retainer. Most people run the SRS without the buffer retainer for ease of maintenance.

   

  The SRS™ comes with Red LOCTITE on the front metal stop and Blue LOCTITE for the bottom bumper, when reassembling we recommend reapplying LOCTITE.
