Specialized high-accuracy 12.7×108mm 7N34 59.0 gram FMJ and AP sniper cartridges have been developed for Russian .50-caliber sniper rifles such as this rifle.

Large caliber machine gun cartridges can also be used for firing, but with limited accuracy.

With 7N34 ammunition, its accuracy is claimed as 1.5 MOA at 100 meters or better, equal to the Barrett M107.

The OSV-96 folds in half in between the barrel/chamber and receiver compartments to shorten its length for ease of transportation.

The rifle features a free-floating barrel in combination with a large muzzle brake to greatly decrease its recoil.
