Description
The Medium Clamp-On style Compensator is sepcifically for the RIA Shotguns that do not have external threads on the end of the barrel.
This item clamps onto the end of barrels without threads allowing the addition of a compensator to older shotguns or even newer ones that do not have threaded muzzles. If your outside barrel diameter is smaller than 20mm but larger than 18.5mm this compensator should work on your barrel.
Please NOTE: the compensator comes with everything you need to install it.
Installation Instructions: We recommend that you have a professional gunsmith install this item. This compensator has 6 screws that clamp it onto the end of your barrel. For best results the screws need to be removed completely, a drop of oil placed under each screw head (not on the threads), and then reinstall the screws tightening each screw 1/8 of a turn at a time and alternating side to side until tight.
