The M93 Crna Strela is an anti-materiel rifle of Serbian origin. It was developed by Zastava in the early 1990's. It is possible that there was an earlier Zastava anti-materiel rifle called M84, but little information is available.

The M93 uses the proven Mauser bolt action system. It feeds from a 5 round detachable box. The furniture is made out of high strength plastics. The long barrel is heavily fluted and features a multislotted muzzle brake that reduces recoil with 62 percent. The bipod is mounted in front of the magazine and near the center of mass.

The M93 is available in 12.7x99mm NATO and in 12.7x108mm Soviet. Both rifles use a 5 round detachable box magazine. Both rifles feature a similar performance, even though the model for Soviet ammunition has a much longer barrel. The maximum effective range is quoted to be 1.600 meters.

The M93 is in use with Serbian forces and was used during various conflicts. The M93 is also been exported to various nations.
