This is a test of my steel bunker door design. The door held up well against .22, .45, 9mm, and 5.56mm carbine AR15 fire.




The design uses 1/8" angle iron welded into a continuous plate, multiple sheets of plywood, and a 3" square tube steel inner frame. As evidenced in the video, this design very effectively traps and destroys small arms fire. I recommend this door design for anyone building a home survival shelter or bunker.
