Which firearms take this part
Studio
Every firearm this threads onto, resolved
Not a list the maker typed out: the answer comes from the interface this part needs and the mounts each firearm exposes, so it stays right when either one changes.
- The reverse lookup on every part in the catalogue
- Interface standards, platforms and fit overrides
- The same answers through the API and the MCP server
Requires a signed-in GunSpec account on the Studio plan. The answer is computed per firearm, so it is not part of the public record.
