9mm Bolt Carriers ONLY: For proper function of the SRS-9 in your 9mm rifle or pistol, the extra weight on the back of the bolt carrier needs to be removed. It is held in with a spring pin.

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 our without the buffer retainer. Most people run the SRS without the buffer retainer for ease of maintenance.
