The M93 Black Arrow is a .50 caliber anti-materiel rifle developed by Zastava to replace some applications of the RPG with better accuracy. It was originally produced in 12.7x108mm, the same as used in the DShK machine guns then in use by the Serbian military. Later production (including this example) included 12.7x99 Browning, which is much more common in Western nations.

The mechanics of the gun are very interesting, as it is essentially a scaled-up French FR-F1 with the exception of the front half of the bolt, which uses Mauser-style locking lugs and extractor.
