Phase 5 Weapon Systems 12GSF 12ga Shotgun Follower Blue 7075-T6 Aluminum - W/O Mag Crimps

The Phase 5 Weapon Systems 12GSF is a precision-machined 12 gauge shotgun magazine tube follower that drops into most 12ga tubes for a high-visibility, low-drag upgrade over factory polymer followers. It is CNC-machined from solid 7075-T6 aluminum bar stock in the USA, so it slides smoothly through the magazine tube for noticeably more reliable shell feeding under recoil.

This version is finished in a bright blue anodized coating with crisp white lettering on the face, letting you confirm at a glance whether a round is chambered or how many shells remain in the tube. Whether you run a defensive shotgun, a competition rig, or just want a more serviceable magazine tube system, the 12GSF is a simple drop-in upgrade that improves both function and visibility.

This specific variant is built for 12ga magazine tubes without magazine crimps, so it installs without having to modify or remove factory dimples. The 12GSF is compatible with Benelli M2 and M4 semi-automatic shotguns and other similar 12ga tube setups. The aluminum construction adds virtually no meaningful weight while standing up to years of recoil and repeated loading.
