The Nordic Components Mossberg 12 gauge shotgun magazine extension tube barrel clamp is purpose-built to stabilize extended magazine tubes on shotguns with heavy or overbored barrels and large barrel-to-magazine offsets. If you've upgraded to a magazine extension on a Mossberg 590, 590A1, 835, 935, or 930SPX—or run a Benelli Nova or Supernova—this aluminum clamp bridges the gap between barrel and extension with the kind of rigid support that keeps everything locked down during shooting, handling, and transport. The matte aluminum finish resists corrosion without adding bulk, and the two-piece design clamps securely around your barrel without permanent modification.
Each clamp half is drilled with a centrally-located 10-32 threaded hole, giving you a solid platform to add sling studs, tactical rail sections, QD mounts, or other mission-specific attachments. That flexibility means you're not locked into one configuration—adapt the clamp as your shotgun's role evolves, whether you're setting it up for 3-gun, home defense, or duty work.
Heavy-walled barrels and extended magazines can create alignment challenges and vibration. This clamp solves that by bearing down on the barrel, reducing flex and harmonics that compromise accuracy and handling. Installation is straightforward, and the barrel clamp doesn't interfere with normal field stripping or maintenance.
