Remember the dude that made the AK-47 out of a shovel? Well he made something else out of some metal bits, a homemade Glock lower receiver frame dubbed the Iron Glock. Check out the entire build thread here. Why would someone want to do this you ask? Well just like with 80% AR-15 lower receivers there’s no paper work needed, and since the frame/receiver is considered the firearm you can buy a Glock slide and barrel and pretty much make a complete pistol. Don’t like the bare metal pistol grip? He even stuck one of his creations into a Glock airsoft frame.
Hell yeah! That is awesome!
