texasgunguy:Browning M1919A4Developed in the mid 1930s the M1919A4 was by far the most common variant and the first model of the M1919 designed for general use and featured the now standard 24" barrel (earlier variants were designed as tank and cavalry machine guns and had a shorter 18" barrel). Original M1919A4s featured a different heat shield with horizontal slots similar to those found on earlier models as opposed to the circular perforations found on the vast majority of M1919s. Early M1919A4s also featured a rotating notched bar on the right side of the receiver which was used to hold the bolt in the open position to prevent ammunition cook-offs in a hot barrel, a feature required by the Army at the time. This requirement, and hence the bolt latch, was dropped in 1943 (meaning that any M1919A4 lacking this latch prior to 1943 is incorrect) although the bolt latch remained present on some weapons until the 50s.Browning M1919A4Weight: 31 lb (14 kg) (M1919A4)Length: 37.94 in (964 mm) (M1919A4)53 in (1346 mm) (M1919A6)Barrel length: 24 in (609 mm)Cartridge:30-06 Springfield (U.S.)7.62 x 51 mm NATO (U.S.)303 British8 mm MauserAction: Recoil-operated/short-recoil operationRate of fire: 400–600 round/minMuzzle velocity: 2,800 ft/s (853.6 m/s)Effective range: 1,500 yd (1,370 m) (maximum)Feed system: 250-round belt -- source link
