More evidence of the futility of gun confiscation. "Homebuild 20mm cannon project defines stout recoil."
Josh, a 4Chan user, finally got his ATF Form 1 approved and commenced to building a single shot 20mm cannon project that just screams recoil pad. As the builder has a stockpile of 90 rounds of M55A2 TP, the same electrically fired stuff used in the Vulcan 20mm cannon, the NFA defined destructive device uses an electrical system constructed of two CR123V batteries and a boost converter that pumps juice into a 320uf flash photo capacitor to trigger the primers.
