This is a 3D printable Remington 870 Express Super Magnum Shotgun Magazine Plug.

I generally use my 12GA Remington 870 pump shotgun during waterfowl season. Many US states limit the number of shells you can have in the firearm at any one time to 3 shells (1 in barrel + 2 in magazine tube). This magazine "duck" plug can be easily installed and only allows for the shooter to load a maximum of two 3 inch shells into the magazine tube.

I printed mine with 99% infill, no supports, and standing straight up. It's a very simple model (basically just a plastic tube), but it's the perfect dimensions for this specific shotgun. Everything else I've ever used would sort of rattle around in the magazine tube, which would be a bit annoying. Costs ~30 cents to make yourself versus ~$8 to buy online. Figured I'd share.

Be careful & enjoy!
