The TacStar Mag Extension Rem 870 +5 is a purpose-built upgrade for Remington Model 870 12 Gauge shotguns, adding meaningful capacity while maintaining a clean, streamlined profile. Machined from tough 6061 aluminum and finished in matte black, this modular extension tube is designed for smooth function and a precise fit, with a recessed section to accommodate a magazine or barrel clamp when needed.

This extension increases the magazine capacity of compatible Remington 870 12 Gauge shotguns by five rounds, making it a practical choice for extended range sessions, training, or hunting where additional shots between reloads are beneficial. The included high-visibility follower and long magazine spring support reliable feeding and allow fine tuning of the setup. TacStar’s attention to machining quality and thoughtful modular design reflects the brand’s reputation for durable, well-engineered shotgun accessories.
