Nordic Components MXT Magazine Extension Kit, +9 Capacity$64.79
Availability: In Stock
The Nordic Components MXT Magazine Extension Kit +3 is a no-frills capacity boost for 12-gauge shotgunners who need more rounds on tap. Whether you're running 3-gun competitions, tactical training, or just want deeper magazine wells for hunting, this aluminum extension tube system lets you add three rounds to your shotgun's magazine tube. It's built from 6061 aluminum—lightweight and durable—and comes with everything you need to install it: the extension tube, the correct-length spring, and an end cap. The only thing you'll need to source separately is the attachment nut that matches your specific shotgun model.
Nordic Components engineered these kits with practical details that matter on the line. A relief groove machined into the tube (on +2 through +9 extensions) prevents barrel clamp creep, so your setup stays consistent after you break it down between stages. That same groove is offset, giving you the option to reverse the tube and adjust its position if you need fine-tuning—useful when you're dial-in your gun's handling or accommodating different shooting positions. The tube is machined with matching threads on both ends, so reversing it is straightforward.
If you're running a Benelli M1 or M2, Nordic Components makes flush-fit versions: the +3B for 18.5" barrels and +5B for 21" barrels, designed to keep the extension aesthetic and functional without adding bulk. For other shotgun platforms, measure your barrel and select your capacity, then grab the correct extension tube nut for your gun's model. It's a direct, honest upgrade for shooters who want more ammo capacity without complications.

The MXT +3 is universal fit for 12-gauge shotguns, but you must purchase the correct Nordic Components Extension Tube Nut that matches your specific shotgun model (sold separately). If you own a Benelli M1 or M2, Nordic Components offers Benelli-specific flush-fit versions; choose +3B for 18.5" barrels or +5B for 21" barrels.
The kit includes the extension tube, the correctly sized spring for that tube, and an end cap. You'll need to purchase the appropriate Extension Tube Nut separately—it must match your shotgun's model and threads.
Yes. The relief groove is machined off-center, so you can reverse the tube to adjust its position. The tube also has matching thread pitch on both ends, making reversal straightforward. This flexibility helps you fine-tune fit and handling for your shooting style or gun setup.
The relief groove prevents the barrel clamp from creeping or shifting after you take your shotgun apart for cleaning or maintenance. It ensures your setup stays consistent and repeatable between range sessions or competition stages.
