The 20 inch genuine, factory brand Remington Model 870 12 Gauge Magazine Extension Kit increases mag tube capacity by 3 extra rounds. The dependable, factory made magazine extensions provide additional round capacity for tactical operations and competition. The all-steel extension tubes attach directly to the end of the magazine tube. The included magazine clamp attaches around the barrel and the extension for added support. The magazine spring is formed from high strength music wire that resists "set" and won't weaken over time. It has a matte blued finish.
