The Kb wz. 35 used the 7.92×107mm DS Cartridge, capable of penetrating up to 30 mm of armor at 100 meters angled at 90˚ or 15 mm of armor at 300 m angled at 30˚. The weapon was bolt-action and possessed a four round magazine. A trained operator could average a rate of fire of about 9-10 rounds per minute. Due to the 1,274 meter per second muzzle velocity, the lifespan of the wz. 35's barrel was relatively short at 300 rounds per barrel. The iron sights of the weapon were fixed by default to 300 meters. For better accuracy, the wz. 35 also comes equipped with a folding bipod.
