Phase 5 Weapon Systems Low Drag, High Visibility M $19.99
Availability: In Stock
The Phase 5 Weapon Systems Low Drag, High Visibility 12 Gauge Shotgun Follower is a precision-machined upgrade designed to replace the factory follower in most 12-gauge shotgun tube magazines and extension tubes. If you run a Benelli M2 or M4, Mossberg 500 or 930, Remington 870, or similar platform and want faster magazine checks and smoother feeding cycles, this is a straightforward drop-in replacement that delivers real tactical and practical advantages.
Machine-cut from 7075 T6 aluminum—a material about 80% stronger than standard 6061 alloy—the Phase 5 follower is engineered for durability and burr-free operation. The bright anodized finish (available in red, green, or blue) and white lettering serve a purpose beyond style: they make it instantly obvious whether your magazine is loaded or empty, cutting down fumbling during range sessions, competitions, or hunting. The open center design contributes to the low-drag profile, reducing friction as rounds feed and eject.
Installation is simple—it's a drop-in replacement on compatible shotguns—but compatibility matters. The 12GSF will not fit tubes with spring/follower retention dimples; if your shotgun has them, you'll need to modify or swap the tube. Notably, it won't work with Benelli Nova/SuperNova/Vinci variants, Browning BPS or A5, CZ 612 or 712, FN SLP, Franchi 912 Variomax, or Winchester SX2/SX3 models. Keltec KSG users note that two followers are required per shotgun.
A small upgrade that meaningfully improves the feel and feedback of your shotgun—exactly the kind of refinement that compounds into better shooting when every detail works together.
| Gauge | 12 |
| Material | 7075 T6 aluminum |
| Finish Options | Red, green, or blue anodized with white lettering |
| Design Type | Low-drag, open-center follower |
| Installation | Drop-in replacement (for compatible tubes) |
The 12GSF fits most factory 12-gauge magazine tubes and extensions on Benelli M2 and M4, Mossberg 500 and 930, Remington 870, 1100, and 11-87, Keltec KSG (two required per gun), and Stoeger M3000. It will NOT fit Benelli Nova, SuperNova, Vinci, or Super Vinci; Browning BPS or A5; CZ 612 or 712; FN SLP; Franchi 912 Variomax; or Winchester SX2 and SX3 models. Critically, it does not work in tubes with spring/follower retention dimples—if your tube has them, you will need to remove them or replace the tube entirely.
The Phase 5 is machined from 7075 T6 aluminum, approximately 80% stronger than standard 6061 alloy, and finished with a smooth, burr-free surface for reduced friction. The bright anodized color and open-center design also make it simple to visually or tactilely confirm whether your magazine is empty—a practical safety and operational advantage factory followers don't offer.
For most shotguns, one follower per magazine or extension tube. Keltec KSG owners require two followers per shotgun.
On compatible shotguns and tubes without retention dimples, yes—installation is straightforward. If your tube has dimples, they will need to be removed or the tube replaced before the 12GSF can be installed.
