Overview

Built for Remington 870 setups using a two-round magazine extension, this replacement spring is intended to keep the magazine system functioning as designed when a standard spring is no longer the right fit. It is made from 17-7 stainless steel and heat treated for added durability, with the material choice aimed at helping reduce issues associated with rusty magazine springs. The spring can also replace a standard magazine tube spring, though trimming is required for proper fit. For hunters and field users who maintain their shotgun carefully, it offers a straightforward maintenance part rather than a performance upgrade.

Considerations & Trade-offs

  • Designed specifically for Remington 870 setups with a two-round magazine extension, so it is not a universal spring.
  • Can replace standard magazine tube springs, but trimming is required for that use case.
  • The 23 in. overall length means it is intended as an extended replacement rather than a drop-in fit for every configuration.
  • Its stainless-steel construction is aimed at reducing corrosion-related issues, but the product data does not support broader performance claims beyond that purpose.
