LAR15 556/223 10rd Pistol Magazines with 3D extender

Short pistol mags with 3D printed 30-round extensions. 
 

I will add more photos when I’m home, these magazines give you the feel of a 30 round full sized mag with 10 rounds of 556/223 in them. They’ve held up to some drop tests and fully loaded mag dumps, no failures to load feed or eject.
