Collection: Magazine Extensions
Shotgun magazine extensions are one of the most effective ways to increase capacity without changing your platform. More rounds on board matters, but only if the system runs reliably.
Poorly made extensions cause feeding issues, loosen under recoil, or fail when you need them most. Fitment, spring quality, and construction all matter.
We carry shotgun magazine extensions that install clean, stay tight, and feed consistently, so you get the extra capacity without sacrificing reliability.

Shotgun magazine extensions are one of the most effective upgrades you can make. More rounds on board without changing your platform — but only if the system runs reliably under recoil.
We carry extensions for the most common platforms: Remington 870, Mossberg 500/590, Benelli M4, and more. Every extension we stock is tested for fitment, spring quality, and feeding consistency.
