This adapter lets Remington 597 22-round magazines run in TUFF-22 compatible rifles and receivers legally. It mounts to the magazine and stays on the magazine, so once installed, your 597 mags become dedicated TUFF-22 feed devices.

This is not a universal fix and it is not pretending to be one. It is made specifically for TUFF-22 receiver geometry and only works with TUFF-22 receivers. That receiver-specific design is the whole point, ensuring that 22 round magazines cannot be used on a standard 10/22 receiver once affixed to the magazine, since using magazines larger than 10 rounds on a standard 10/22 is not legally permissible in Canada (because pistol Ruger 10/22 charger was imported to Canada, which subsequently resulted in a legal limitation, that’s to the infinite wisdom of you-know-who).

It ships with installation hardware included, so you have what you need to get the adapter mounted without digging around for tiny parts before you can even start.

In the spirit of a project built with help from the people who actually use this stuff, the digital file is also available as a free download. This adapter was developed collaboratively with other members of the community, refined through shared input, testing, and iteration instead of being cooked up in isolation and declared perfect on day one.

Simple idea, properly executed:
Adapter stays on the magazine, works only with TUFF-22 receivers, installation hardware included, and the file remains freely available to the community that helped shape it.

For Canadian buyers, this adapter is intended for TUFF-22 receiver use only and remains attached to the magazine rather than serving as a general-purpose conversion.
