Carlson's Universal Shotgun Plug - Fits All Gauges, 2-Pack

A shotgun plug reduces magazine tube capacity to meet hunting regulations that mandate two-round limits in the field. The Carlson's Universal Shotgun Plug fits all gauges and ships as a two-pack, making it a practical solution for hunters who use the same gun under different legal requirements—waterfowl season versus upland hunting, for instance—or who want a backup. Unlike gauge-specific plugs, this universal design adapts to your gun rather than the other way around, whether you're running a 12, 20, 28, or .410.

The plug is sized to work out of the box on most shotguns, reducing capacity from a typical four-round tube to two rounds. The real flexibility comes from its trimming capability: you can carefully cut the plug to length using standard tools like pruning shears, PVC shears, or a hacksaw to match your specific gun's magazine tube dimensions. The tuning process is straightforward—remove 1/4" to 1/2" at a time and test-fit with the largest shells your shotgun is rated for until exactly two rounds fit comfortably. That hands-on approach takes a few minutes but ensures a snug, reliable fit.

Two plugs in the pack gives you a spare or lets you maintain multiple shotguns without swapping one plug between them. Installation requires no permanent modification to the gun; the plug simply sits in the magazine tube and can be removed if regulations change or you need full capacity again. It's a straightforward, affordable way to stay compliant with waterfowl and other regulated hunts.

Frequently Asked Questions

What shotguns does this plug work with?

The Carlson's Universal Shotgun Plug is designed to fit all gauges, including 12, 20, 28, and .410. It comes full-sized and can be trimmed to match your specific gun's magazine tube.

How do I trim the plug to fit my shotgun?

Start with the full plug and use pruning shears, PVC pipe shears, or a hacksaw to remove 1/4" to 1/2" at a time. Test-fit after each cut using the largest shells your shotgun is rated for; stop when exactly two rounds fit snugly in the magazine tube.

Is the plug permanent or removable?

The plug is fully removable and requires no permanent modification to the gun. You can take it out or replace it anytime, making it ideal if you hunt under different regulations in different seasons.

Why would I need two plugs?

Two plugs allow you to keep separate shotguns pre-tuned to two-round capacity, or provide a spare. This avoids the need to swap a single plug between guns.
