JMT AR15 lower receiver machine guide for CNC

grabcad

The AR15 James Madison Tactical polymer 80% lower receiver fixture cutting guide, sold by JMT, includes a plastic machining guide that holds and directs users as they manually mill their lower. However, if you're using CNC like me, you only need a 3D file for your tool paths. Unfortunately, JMT wouldn't provide this, so I created a reversed fixture with all key points needed for milling and drilling, which can be used in conjunction with their fixture to hold the JMT lower securely in a CNC mill. Note that you still need to purchase and use the 80% lower from JMT to make use of these files; they include XFA files compatible with OneCNC XR4 and ready for post-processing tool paths.
