These STL files let you print an adapter that allows Remington 597 22-round magazines to work with TUFF-22 compatible receivers. The design mounts to the magazine and stays with the magazine, turning your 597 mags into dedicated TUFF-22-compatible units that are compliant with the Canadian law.

This is a receiver-specific design made for TUFF-22 platforms only. It is not universal, and it is not trying to be clever about that. The whole point is a clean, purpose-built adapter for a specific setup.

The files are offered as a free download because this project was developed collaboratively with the community. People contributed ideas, testing, feedback, revisions, and the kind of practical input you only get from builders who actually use their gear.

And yes, support is still available. Even though the files cost nothing, we are still happy to help with reasonable questions about printing, setup, and getting the adapter running properly. Free does not mean abandoned.

What you get:
STL file and STEP  for the adapter design developed for TUFF-22 receiver compatibility. If you want to remix it – go wild.

What you should know:
Designed for TUFF-22 compatible receivers only (and bubbas willing to put that Dremel to use)
Adapter stays attached to the magazine
Community-developed and offered free of charge
Support available because unfinished projects are annoying
