Will this work in a Mossberg shockwave without modifications? Expert Answer

The Phase 5 Weapon Systems Inc Low-Drag Shotgun Follower 12 Gauge will fit most factory 12 gauge magazine tubes and should work fine with a Mossberg Shockwave.

So this would not work with a maverick 88? Expert Answer

The Phase 5 Weapon Systems Inc Low-Drag Shotgun Follower should be compatible as it fits most factory 12-gauge shotgun magazine tubes and extension tubes without spring/follower retention dimples. I would still recommend reaching out to the manufacturer directly for fitment confirmation.

Very nice upgrade by Ryan Boone, Verified Owner, March 1, 2026
The OEM follower that came with my new 590A1 seemed to work ok but was just a cheap piece of thin metal. This follower is much nicer and is clearly “slicker” when riding in the magazine tube. Only improvement I would make is if the manufacturer wou...
