Weatherby Magazine Extension

thingiverse

+2 magazine extension, designed for Weatherby PA-08, but should work with any model that has an approximately 1" 12 pitch single start thread. (Rumor is the Benelli Nova uses the same threading, and I'm sure many others likely do, especially the Turkish made models) I cleaned up the threads with a tap for testing, and either a 1"x12 or a 25mmx2mm will work. May require modifying the magazine tube, the Weatherby for instance has a slight rolled edge and a dimple to hold the spring in place, it has to be cut or ground back to allow the spring and follower through. Mostly just the spring. Might needs some standing inside the extension too, depending on printer setup. I sold the shotgun this was made for a long time ago, and forgot all about it, so I'm not going to any more development or troubleshooting on it. I've included the source file along with a Fusion360 that might be identical, or might be a test design I abandoned...it's been too long for me to be sure. Feel free to do whatever you like with this model.
