The Mk44 Bushmaster II is a 30 mm chain gun manufactured by Alliant Techsystems. It is a derivative of the 25 mm M242 Bushmaster, and uses some 70% of the same parts as the M242 while increasing the firepower by as much as 50% with the 20% increase in caliber size. The barrel is chromium-plated for extended life. The gun uses standard GAU-8 Avenger ammunition that is available in API (Armor-Piercing Incendiary), HEI (High-Explosive Incendiary) and APFSDS-T (Armor-Piercing Fin-Stabilized Discarding Sabot-Tracer) variants.

    I guess this is intended to replace our venerated M2 .50 cal. I'll believe that 10 to 20 years, from now.

    @Hooksdown. The bushmaster chain guns are in a different class then the .50 cal and serve a different purpose..... not a replacement.

    These are old weapons systems. They keep saying reliability but thats some BS. When it jams, its a real pain to remove the feed rounds on the 25mm. I don't trust it for a cold war style battle but in Iraq vs light targets its a monster.
