TOKAREV 12GA One-Round Magazine Tube Extension - Enhanced Capacity & Performance

The TOKAREV 12GA One-Round Magazine Tube Extension adds a single round of capacity to your TX3 series shotgun, bringing your magazine tube to a practical 5+1 configuration with 2¾" shells. If you run a Tokarev TX3 and want quick, reversible capacity without gunsmith work, this extension slides on in seconds and returns your shotgun to stock condition just as fast. It's the kind of no-fuss upgrade that makes sense for hunters who want a little extra margin without permanent modifications.

Installation requires no drilling, welding, or permanent changes to your shotgun. The extension seats over the factory magazine tube and locks in place—you can remove it anytime without leaving a trace. That makes it ideal if you're switching between hunting trips with different capacity needs or if you simply want to keep your TX3 in its original configuration for resale or storage.

A one-round gain might sound modest, but in the field it can mean the difference between reloading and making your shot. For upland hunters, waterfowlers, and 3-gun competitors running a TX3, this extension is a simple way to squeeze more utility out a shotgun you already trust.
