Extend times between reloads with the GG&G® +3 Shot Magazine Extension for Remington® 870™. The magazine extension tube is machined from 6061-T6 aluminum construction with a Type III hard anodized corrosion-resistant finish while the magazine extension tube nut is CNC machined from corrosion-resistant solid steel bar stock for superior durability. This magazine tube lets you add 3 additional rounds to your magazine tube shotgun and is perfect for military, law enforcement, or home defense use. Even better, the end cap of this extension tube can be removed for easy cleaning and maintenance or the use of a magazine plug. Lifetime warranty. NOTE: This mag tube extension protrudes approximately 2.25” beyond the barrel of an 18.5” model. This may cause carbon build-up, scoring, or discoloring to the mag tube extension, especially if you are using a ported choke tube and is not covered under warranty. Made in USA.
