Terni M91 Carcano Semiauto Conversion
This video details an experimental semi-automatic conversion of a Terni M91 Carcano rifle, performed by the Terni Arsenal. Unlike typical gas-operated systems, this conversion utilizes a short recoil mechanism where the barrel and bolt move together. The original bolt with a 90-degree throw is replaced by an 8-lug bolt requiring minimal rotation for unlocking, facilitated by an angled wedge. The rifle remains chambered in 6.5x52mm and uses standard 6-round Mannlicher clips. The base rifle was manufactured in 1908, though the conversion date is unclear. The video expresses gratitude to Beretta for the opportunity to examine this unique firearm.
