When you're running an extended magazine tube or swapping out a shot magazine spring, the Nordic Components 45-inch extension tube spring gives you the length you need without the guesswork. This spring ships coiled and overlong on purpose, letting you trim it to the exact fit your tube requires with simple cutting instructions included in the box.
A tired or worn magazine spring is one of those sneaky reliability issues that creeps up on shotgun owners. Whether you've got thousands of rounds through your gun or you keep your magazine compressed and loaded for defense, springs lose tension over time. The result is rounds that don't feed cleanly, gaps in your shooting rhythm, or worse. Upgrading to a fresh Nordic spring restores reliable feeding and positive pressure that pushes every round out when you need it.
The 45-inch length gives you room to work with. Most users trim somewhere between 24 and 32 inches depending on their tube length and how much spring pressure they want, though this varies by shotgun model and personal preference. The included instructions walk you through the process. Real-world feedback shows that extra length translates to crisp, positive feeding that noticeably beats worn factory springs or undersized replacements. You can always cut more, but you can't add back what you've already trimmed, so the overlong design lets you dial in your setup the right way the first time.
Nordic Components springs are known for solid performance at fair pricing. This is the standard strength version, well-suited for 2.75-inch loads and general purpose shooting. The coiled design ships compact and protects the spring during transport until you're ready to install it.
Start with leaving the spring 12 to 18 inches longer than your magazine tube. Most users end up cutting 15 to 20 inches off depending on their specific tube and how much spring tension they want. The included instructions help guide this, but trim gradually and test fit before cutting more. It's better to leave extra than risk cutting too much.
This is designed for shotguns with extension tubes and standard magazine configurations. It works with popular models like Remington 870, Mossberg 500, and most semi-auto shotguns that accept aftermarket extensions. If you're using a factory magazine without an extension, check if your shotgun needs a different spring length or type.
If your shotgun is feeding reliably with good velocity pushing the last round out, your spring is fine. But if rounds aren't feeding cleanly, feel sluggish coming out of the magazine, or you've had your gun loaded for years, a fresh spring is cheap insurance for reliable function. Heavy use in tactical or competition settings means replacing springs more often.
This is the standard strength spring, suitable for 2.75-inch loads and general purpose shooting. Nordic Components also makes heavy-duty springs for specialized applications, but check compatibility first since some shotgun models are sensitive to spring tension variations.
