"NOCK'S FORM
"Often erroneously referred to as a ‘Knox Form’, this flat section on the barrel adjacent to the receiver ring on many bolt-action rifles is designed to permit the proper seating of the barrel-wrench during fitting or removal of the barrel. It performs the secondary function of a reference plane for correctly setting the iron sights. The Nock's Form is believed to be an invention of the Nock family of 18th and 19th Century London gun-makers, whose name the feature bears to this day." -- (Australian Arms Collectors' Association)
My Enfield No.1 III* has a Nocks's Form (flat on the barrel to next to the receiver). The real No 5 will have additional flutes cut in the barrel near the Nock's Form.
