Description
If your shotgun still has that mushy plastic follower rattling around, it's time for an upgrade that feels the difference. The Phase 5 follower swaps in easily and makes loading smoother with far less drag on the spring. You'll immediately notice how much easier it is to fill the tube, especially when pushing shells against a tired mag spring.
Low-Drag Design That Makes Sense
The bearing surface is roughly one-third what factory followers have, which means less friction slowing down your shells on the way in. Made from 7075-T6 aluminum bar-stock machined right here in the USA, this follower is 65 percent stronger than standard aluminum options from other makers. The anodized finish handles the elements, and the shape keeps things moving without binding up in the tube.
See It Clear, Feel It in the Dark
Bright green anodizing with white lettering makes it easy to see at a glance whether your magazine is empty. The center hole works just as well tactilely, so you can verify the tube is clear by feel when you can't rely on your eyes. This matters more than you'd think during a fast reload or in low light.
Compatible Where It Counts
This follower fits most factory 12-gauge magazine tubes and extension tubes without retention dimples. Models like Mossberg 500 and 930, Remington 870 and 1100, Benelli M2 and M4, and KelTec KSG are all compatible. One note: if your mag tube has factory dimples meant to lock the follower in place, you'll need to remove them or swap to a smooth tube for installation. It's a simple mod on most guns.

Frequently Asked Questions
Will the Phase 5 follower work with my shotgun's factory magazine tube?
It will fit most factory 12-gauge tubes and extension tubes as long as they don't have retention dimples. These are small indents the factory adds to lock the follower in place. If your tube has dimples, you'll need to remove them or swap to a smooth tube before installing this follower. Popular models like the Mossberg 500/930, Remington 870/1100, and Benelli M2/M4 are all compatible.
What's the benefit of aluminum over a plastic follower?
Aluminum is significantly more durable and won't crack or degrade like plastic can after extended use. The Phase 5 design also reduces bearing surface friction, making the magazine load smoother and easier. Combined with the bright color for quick verification, you get both better function and practical visibility improvements.
How does the center hole help verify an empty magazine?
The hole lets you see clear through the follower at a glance, making it instantly obvious the tube is empty. In situations where you can't see clearly or are clearing the magazine by feel alone, you can stick your thumb through the hole to confirm there's no round underneath. It's a simple feature that makes a real difference in the field.
Is installation straightforward?
Installation is simple if your magazine tube doesn't have retention dimples. You just remove the spring and old follower, drop in the new one, and reassemble. Some factory tubes use Loctite or may be tight, so you might need a heat gun if things are stuck. Check your specific gun model for any fitment notes if you're unsure.
