The Nordic Components Beretta/Nova/CZ 12GA Extension Nut (brand part no. NUT-BR-12-00) is the magazine cap replacement required to install a Nordic Components MXT 12-gauge shotgun extension tube kit. It threads on in place of the factory magazine cap and provides the mounting interface the MXT tube kit needs to attach securely. This nut is fitted for the Beretta AL391 Xtrema pattern, along with Nova and CZ 12-gauge shotguns sharing that mount. It ships in a black finish to match factory magazine tube hardware. Without this nut, an MXT extension tube kit cannot be installed on a compatible shotgun.
