FreeCAD and STL files for an AR-15 lower milling jig. For a demonstration of it in use: https://odysee.com/@swolebro:4/swolebro-AR-15-jig-v3.2-tutorial:c And this GitHub project for any questions, comments, concerns, etc. https://github.com/swolebro/swolebro-youtube/issues I don't expect this jig will have any more updates in the near future (not until I build an AR-10, anyways), but I do have some videos left to do going over blueprints, how these files are designed, etc. so stay tuned for more.
