Still getting gas leakage from your sealed-off Tavor ejection port? This persistent issue bothered the team at Manticore Arms, too, so they developed their Tavor Gasketed Port Cover to provide a truly firm and gas-proof seal. The Manticore Arms Gasketed Port Cover is built using 6061 aluminum and features an interior and exterior panel with a rubber gasket placed between each panel. The two panels are tightened together by two screws, which compresses the rubber gasket in the middle and provides a better compression seal against gas flow. Other features in the Manticore Arms Gasketed Port Cover includes a quick-detach sling-swivel pocket, as well as fully ambidextrous compatibility. Each port cover is made in the USA and ships with all the tools needed for installation.
