SJC Shotgun Compensator

Installation Instructions

Contact S & J Customs first if you do not understand and accept the following instructions:

  1. It is your responsibility to make sure your shotgun is unloaded and safe before starting.

  2. Please carefully verify that the compensator provided has the same thread diameter and pitch as the threads on your barrel. These comps are made to factory produced thread pitches for the indicated shotgun and model. They should screw onto your barrel with relative ease for several revolutions. If it does not, stop immediately and seek assistance

  3. Due to the broad range of shotgun barrels and ammo choices, you are 100% responsible for verifying you are installing the compensator with adequate bore clearance for your bore gauge and ammo choice.  The SJC Titan Shotgun compensators have non-restricting but purposefully tight bores and are made out of aircraft grade aluminum to minimize weight. They may show baffle wear from un-burned powder. Normal wear is self-limiting and does not affect performance. However, excess wear and safety issues will occur should ammo payload contact the comp. To minimize safety issues, they must be installed in good alignment with the barrel’s bore, they must not be used with non-lead shot based loads, or any loads that expand rapidly after leaving the barrel. Failure to follow these guidelines will produce unsafe conditions.

  4. SJC aluminum shotgun compensators are designed to be attached with high temperature Loctite “272” or like products. Aluminum comp threads gall easily. So, use a lubricant if screwing onto the barrel threads for fit testing, index washer selection, or anytime without the benefit of the Loctite.

  5. After verifying all safety concerns are addressed, degrease and dry threads before coating the barrel threads and compensator threads liberally with the 272 Loctite.  Immediately screw the aluminum compensator onto the barrel aligning  the top of the compensator with the top of the shotgun.  Make sure no compound is left in the barrel or bore of the compensator. Allow to cure per the Loctite manufacturer’s recommendations before test firing.

  6. To remove a 272 Loctited compensator you need to first make sure your shotgun is unloaded and safe. Then evenly heat the threaded area of the compensator using a propane torch to just above the Loctite's maximum holding temperature then unscrew the compensator while using suitable heat protection for yourself, the compensator and any other parts in close proximity to the heat. After heating beyond the adhesive’s maximum temp range, the compensator should always be completely removed, cleaned and degreased before any re-installation is attempted.

  7. Follow the guidelines above, and clean often, removing any lead or carbon deposits to prolong the life of your new SJC compensator.
