AFTE Store - Ruger Blackhawk Automatic Revolver Conversion

A case report on an attempt to convert a Ruger Blackhawk revolver to fully automatic fire. The frame and cylinder from a Ruger Blackhawk were retrofitted with a 30 M-1 caliber barrel and gas piston. A longer cylinder pin was used to contact the gas piston of the M-1 barrel, which drove the pin to the rear upon firing the first cartridge. This action also rotated the cylinder to the next firing position. In concept, holding the trigger to the rear would accomplish fully automatic discharge. In practice, the full auto functioned only once during testing.
