The Scotti used the barrel, receiver(maybe) and bayonet mount from the M91 Carcano and was in 6.5mm Carcano caliber. I don't believe it had anything to do with the P14 Enfield if that is the P14 you're referencing. For those not familiar, The Scotti was a rifle submitted for testing when the Italians were looking for a semi-auto after The Great War. Tom
