JMT AR15 lower receiver machine guide for CNC

AR15 James Madison Tactical polymer 80% lower receiver fixture cutting guide. JMT sells their lowers with a plastic machining guide. It holds the 80% lower square and guides those using a manual mill to machine out their lower. I use CNC and just needed a 3D file to run my tool paths off. JMT would not provide me a 3D model to create my tool paths with. So I reversed the fixture and am providing it for anyone who it can help. This is the overall size and all the key points for milling and drilling. Use THEIR fixture to locate off of and hold the JMT lower in your CNC mill. NOTE: You still need to buy and use the 80% lower from JMT for any value of these files. XFA files are OneCNC XR4 and have the tool paths ready for your post.
With this file you will be able to print JMT AR15 lower receiver machine guide for CNC with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on JMT AR15 lower receiver machine guide for CNC.
