The M305 is a semi-auto firearm chambered in .308 Winchester, built by Norinco in China. From its 559 mm (22.0 in) barrel, Fiocchi 308 Win FMJ (150 gr FMJ) leaves the muzzle at about 2870 fps (875 m/s), adjusted from the 610 mm test barrel the figure was measured in. Zeroed at 100 m, the bullet drops 120 mm by 200 m with 2400 J (1770 ft-lb) left. At the muzzle that is enough to defeat Drywall, Plate Glass, Pine Wood, Brick and Kevlar NIJ IIIA, and not enough for AR500 Steel. It feeds from a 20-round magazine.
Computed by the BallisticEngine engine for this barrel length, zeroed at 100 m, 15 °C, sea level, no wind.
