Nordic Components
The Nordic Components 12 gauge shotgun magazine extension tube barrel clamp is a practical support solution for shotgunners running extended magazine tubes on their defensive or tactical shotguns. Built from lightweight aluminum with a matte finish and hardcoat anodized surface, this clamp attaches directly to the barrel to anchor your extended tube securely in place, reducing vibration under recoil and helping ensure smooth, reliable round feeding when it matters most.
The low-profile design keeps things sleek and snag-free—especially important if you're working in tight spaces or vehicle-mounted scenarios. Rounded edges and flush-mounted hex-head machine screws won't catch on gear or damage interiors. The hardcoat anodized aluminum resists surface abrasion and corrosion, holding up to regular use and harsh conditions without requiring constant babying.
Nordic Components offers this clamp in a Standard configuration as well as a Tactical Rail version that includes a Picatinny-type accessory rail. The rail can be positioned on either the left or right side of the clamp, giving you flexibility to mount lights, lasers, or other tactical accessories to suit your setup. The clamp is available for standard-barrel shotguns and also engineered for heavy-barrel models and Mossberg platforms.
