A video shows a test firing of the new A545 assault rifle, a Russian-made weapon. The rifle uses a counterbalance mechanism that directs most of the propellant gases back inside the gun, improving stability. Because of this design, the weapon has minimal side-to-side or up‑and‑down movement during firing, giving it high controllability in both single‑shot and automatic fire. The video is part of a series of demonstrations of the A545 model.
