In this video, Brandon Herrera dives into the unique—and eerie—world of historical DIY firearms by recreating Ted Kaczynski’s homemade “pipe pistol.” Known primarily for his manifestos and mail bombs, Kaczynski also designed a crude firearm that’s rarely discussed. Brandon builds, examines, and tests this unusual piece to see how it actually performs. It’s a fascinating look at the intersection of history, engineering, and survivalist tactics.
