GMCG Arms Universal 12 Gauge Follower

(1 customer review)



Affordable, durable, and colorful. These 3D printed 12 gauge followers are an easy way to customize your shotgun. Perfect whether you’re looking for something to ensure safety during competition like 3gun, trap or skeet. (And if you want to personalized your gun a bit, no judgement. We all love a good glow in the dark follower.) Please Indicate your preferred color in the order notes. See this blog post for a list of colors we have on hand as well as the colors we can order.

The current design is the result of countless prototypes and hours of testing. It features a hole in the front face of the follower which enables you to check for an empty tube in low lighting scenarios, and 2 channels along the side of the follower for dimpled mag tubes. The length and diameter were specifically chosen to both ensure compatibility with a wide range of shotguns as well as prevent binding within the tube.

One question you may have is why these followers are so affordable. We’ll I can tell you one thing. It’s not because I’m skimping on quality. These followers are affordable because 3D printing is an extremely efficient means of production for small parts such as this. There’s no costly CNC machining, no mold costs, and (at least for these) minimal hands on time to produce them. It’s really just a case of the cost of the polymer you use. And since polymer is so affordable (even for quality filaments) these 12 gauge followers are able to be sold at far lower than the cost of traditionally manufactured followers.

As with all other parts, our 12 gauge followers come with our 60-day money back guarantee and 30% of proceeds go towards charities and causes including the National Alliance on Mental Illness, Deterrence Dispensed, and the Natural Resources Defense Council.


Tested for fit in the following shotguns:

  • Mossberg 500
  • Mossberg 590
  • Maverick 88
  • Winchester 1200
  • Winchester 1400
  • Remington 870

Design should fit in nearly any modern 12 gauge shotgun. On top of that, customers have written in saying that this design is compatible with a Wolff extra-power mag spring, which other designs (both 3D printed and otherwise) may struggle with. If it doesn’t fit in your gun reach out and I’ll work out the necessary edits to make a compatible version or custom version! Other features/specs include:

  • Simple Installation – see the video below
  • Designed in house
  • Durability tested in house

Shipping times will vary based on color chosen. If I have the color in stock, I’ll be able to print and ship in 1-2 business days. If I don’t have a color in stock, it will take a bit longer, but should be no more than 1-2 weeks in most cases. Feel free to email and ask what I have on hand at any given moment.

Installation Instructions

Note: the video below shows an older version of this follower being installed in a Mossberg 500. The process should be fairly similar for any pump action install, but consult with

    These followers are perfect for adding some custom flair to your shotgun.

    They are super easy to install, and the video that Anthony provided is extremely helpful. Even though I don’t have a ton of experience in taking apart my firearms past basic dissembly, I was still easily able to switch out the follower in about 10 minutes.

    You can also tell these are quality made. I was concerned that I was getting something “cheap” because of the price, but I can already tell that the material used for the follower is very strong.

    You can’t go wrong, get your own and see for yourself!
