FN Herstal is the original manufacturer of the Quick Change Barrel (QCB) version Browning M2HB .50 cal heavy machine gun.
Today, tens of thousands of the FN QCB™ configuration are in service around the world.
- Fast, easy and safe barrel change procedure
The FN QCB™ system allows the barrel change to be quickly carried out by one person, reduces exposure time to enemy fire and eliminates the need to check and adjust headspace at user level.
The reliability and effectiveness of the M2HB Browning .50 cal machine gun remain unchanged.
- Target effect
A full range of cartridges including Armor Piercing and Armor Piercing Explosive Incendiary allows the FN M2HB-QCB™ to engage soft skinned and light armoured vehicles and buildings or bunkers.
Easy and Quick Conversion in service M2HB machine guns
In service M2HB machine guns of FN Herstal or other origin can be converted in less than 30 minutes by an armorer in a normal workshop using a simple kit of tools and gauges to the FN M2HB-QCB™ configuration.
The modifications to the original M2HB design are limited, so the effect on user training and logistics are minimal.
- One weapon for various applications
The FN M2HB-QCB™ can be used on a wide variety of mountins for vehicles, boats and ships.
