It was internally called the. "NATO Burp Gun", and according to Winchester historian Herbert House, was developed in part (or with the assistance of) Melvin Johnson. The design was a simple tubular receiver with a folding stock that doubled as a vertical front grip when folded. Instead of an external charging handle, it used serrations cut in the side of the bolt, making the gun sleek and compact (albeit more difficult to cock). Today we are looking at the N2 and M4 developmental patterns, both housed at the Cody Firearms Museum. The development program got little further than these prototypes before Winchester abandoned it. Thanks to the Cody Firearms Museum for allowing me access to film these very interesting prototypes!
