The M2 is one of the most effective suppressive fire weapons available for use against soft skinned and lightly armored vehicles, bunkers and buildings. Renowned by generations of warriors for its reliability, range, accuracy and hard-hitting downrange performance, it’s instant offense made simple. Descending from the legendary Browning .50 caliber, now manufactured by FN Herstal and widely considered the ultimate heavy machine gun, today’s M2 Series are simple, highly reliable, extremely effective weapons that adapt to a broad range of battlefield roles. Now the FN M2HB QCB delivers greater versatility and expanded field capabilities with the innovative Quick Change Barrel (QCB) that allows the barrel to be changed by one soldier in seconds and eliminates the need to check and adjust headspace and timing at the user level, speeding set-up and improving sustained fire support in battle. The M2HB QCB modification has been in service worldwide for more than a quarter century and allows any QCB barrel to be mounted on any QCB-modified weapon.
