The file 'AR15 Pistol Grip 3D Printer Model' is (STL) file type, size is 424.5KB.
Here is a pistol grip to fit any AR platform. I created this because I wanted a more upright grip for my AR pistol. I modeled the grip at a 12° angle, so your wrist won't need to bend so much.
Edit 7/16/2016: I added a rifle grip file that kicks the grip at a 20° angle which is more appropriate when the tool is being shouldered.
