The SRS™ comes with Red LOCTITE on the front metal stop and Blue LOCTITE for the bottom bumper, when reassembling we recommend reapplying LOCTITE. The SRS™ can be installed with or without a buffer retainer.
The polymer bumper goes towards the rear of the firearm and the weight mass with the o-ring goes towards the bolt carrier.
Most bolt carriers have a rear opening of over .60?, there are a couple of bolt carriers in the market place that have a rear opening of under .60? and will not function with the SRS. 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.
