JGM Nürnberg-Bong Sportmodell 5mm Long Rimfire Rifle (#1632)

Description JGM Nürnberg-Bong Sportmodell 5mm Long Rimfire Rifle – Serial #1632 This JGM Nürnberg-Bong Sportmodell is a scarce bolt-action rimfire rifle chambered in 5mm Long, serial number 1632. Manufactured in pre-war Germany, this rifle was likely produced for civilian target shooting or youth marksmanship programs, reflecting the country’s strong culture of precision rimfire shooting during the early 20th century. It features a slender hardwood stock, single-shot bolt-action mechanism, and fixed sights. The 5mm Long cartridge was a specialty rimfire round used for ultra-light indoor or short-range training, similar in purpose to 4mm and 6mm Flobert-type systems. Due to its unusual caliber, early serial number, and obscure manufacturer, this rifle holds niche collector appeal—particularly among those interested in vintage German sporting rifles, early rimfire systems, or pre-WWII European shooting culture. A true oddity from a bygone era.
