Winchester's Liberator Shotguns
The Winchester Liberator was a series of four-barrel shotguns designed by Robert Hillberg for low-cost, mass production in counter-insurgency scenarios. Early prototypes like the Mark 1 featured wooden mockups, while the Mark 2 utilized magnesium castings. The Mark 3 evolved to steel tubes for easier manufacturing and was chambered in 12 gauge. Despite interest from Winchester and DARPA, the project ultimately failed to secure military contracts.
