Nordic Components Mossberg 12GA Magazine Tube Nut – Black

The Nordic Components Mossberg 12GA Magazine Tube Nut is a replacement or upgrade component for Mossberg 12-gauge shotguns with tubular magazines. This nut secures the magazine tube to the receiver and barrel assembly, maintaining proper alignment and tension. Upgrading to a Nordic Components nut ensures reliable fitment when installing extended magazine tubes or replacing worn factory hardware.

Machined from steel with a black finish for corrosion resistance and durability. This is a drop-in replacement part for most Mossberg 500, 590, and Maverick 88 models with 12-gauge chambering. Installation requires basic tools and familiarity with shotgun disassembly—no permanent modification or professional fitting needed.
