Nordic Components +7 MXT Extension Tube – 12 Gauge (Black, Requires Magazine Nut)

The Nordic Components +7 MXT Extension Tube adds seven rounds of 2¾-inch shell capacity to your 12-gauge shotgun, transforming it into a high-capacity platform for 3-gun competition, home defense, or extended field work. This magazine extension replaces your factory magazine tube with a longer unit that maintains reliable feeding while significantly increasing your onboard ammunition.

Machined from aircraft-grade aluminum with a durable black anodized finish, the MXT tube is built to withstand hard use and corrosion. Installation requires a compatible magazine nut (sold separately) and basic gunsmithing skills—you'll need to remove the barrel and factory magazine components. Nordic Components designs these tubes with internal anti-tilt followers and precisely machined dimensions to ensure consistent feeding under recoil. Compatible with most 12-gauge shotguns that accept aftermarket magazine extensions; verify fit with your specific model before purchasing.
