The Barnitzke machine gun is a prototype machine gun of late World War II German origin. The weapon uses an unusual delayed blowback operation, where during firing the bolt opening is delayed by the rotational inertia of two flywheels, which are driven by a rack and pinion arrangement on the bolt carrier.{{cite web|url=http://i279.photobucket.com/albums/kk145/gusbucket13/BarnitzkeMG.jpg|title=Archive Photo|accessdate=13 September 2014|archive-date=14 September 2014|archive-url=https://web.archive.org/web/20140914005258/http://i279.photobucket.com/albums/kk145/gusbucket13/BarnitzkeMG.jpg|url-status=dead}}{{cite web|url=http://i279.photobucket.com/albums/kk145/gusbucket13/barnitzkeMG2.jpg|title=Archive Photo 2|accessdate=13 September 2014|archive-date=14 September 2014|archive-url=https://web.archive.org/web/20140914000554/http://i279.photobucket.com/albums/kk145/gusbucket13/barnitzkeMG2.jpg|url-status=dead}}
