About
What it is, and why it matters
The Zastava M91 is a semi-automatic designated marksman rifle chambered in 7.62x54mmR and 7.62x51mm NATO. Based on the Kalashnikov gas-operated action with a 620mm cold hammer-forged chrome-lined barrel, the M91 replaced the older M76 (7.92x57mm) as Serbia's standard squad-level precision rifle. The rifle feeds from a 10-round polymer magazine and achieves 1.5-2 MOA accuracy with match ammunition. Iron sights are graduated to 1,000 meters, with a side rail for the POSP 4x24 optical sight. The M91 has been combat-proven in the Yugoslav Wars, and has appeared in the Syrian Civil War and Yemeni Civil War.
The M91 was developed as Yugoslavia was dissolving, entering service just as the wars began. It proved itself in the intense urban combat of Sarajevo and Vukovar, where its semi-automatic action and 10-round capacity gave designated marksmen a significant advantage over bolt-action alternatives.
Exported to the US civilian market since 2019 by Zastava Arms USA. The 7.62x51mm NATO chambering is the primary variant offered for export.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
