The CZ Bren 2 Ms 7.62 is a semi-auto carbine chambered in 7.62×39mm, built by CZ in Czech Republic. From its 229 mm (9.0 in) barrel, Hornady 7.62x39 FMJ Frontier® (123 gr FMJ) leaves the muzzle at about 2402 fps (732 m/s), adjusted from the 415 mm test barrel the figure was measured in. Zeroed at 100 m, the bullet drops 212 mm by 200 m with 1135 J (837 ft-lb) left. At the muzzle that is enough to defeat Drywall, Plate Glass, Pine Wood and Brick, and not enough for AR500 Steel and Kevlar NIJ IIIA. It feeds from a 30-round magazine.
Computed by the BallisticEngine engine for this barrel length, zeroed at 100 m, 15 °C, sea level, no wind.
