"NATO Burp Guns" - Winchester's 1950s Experimental SMGs
This video explores Winchester's 1950s experimental 9mm submachine guns, internally dubbed the 'NATO Burp Gun.' Developed with potential assistance from Melvin Johnson, these compact SMGs feature a simple tubular receiver, a folding stock that doubles as a front grip, and a bolt cocked via serrations rather than an external handle. The video showcases the N2 and M4 developmental prototypes, both housed at the Cody Firearms Museum, highlighting that the program did not progress beyond these early models before Winchester abandoned it. The presentation is made possible by the Cody Firearms Museum.
