This is my version on a model found on internet: Free STL file AR-15 Magazine Loading Spoon・3D printer model to download・Cults (cults3d.com)
It is no suitable with my PMAGs, and there is no STEP or other editable file.
So I make my own version of it in INVENTOR.
The original has too big gaps between the mag and loader. There is nothing to stop a strip to be bushed into the mag, and may be it is for different strips then mine, or only for metal mags, but it is just not working for me. On the pictures the RED one is the original model.
I make mine to work with PMAGs and I didn't try it wit others brand yet. I have already a few hundreds round loaded and it work perfect.
I hope it will be useful for someone too.
Thanks
The author remixed this model.
