General Dynamics wins $35 million contract from U.S. Army to produce M2A1 quick change barrel conversion kit. "With the QCB conversion kits, the U.S. war fighter can change the machine gun barrel in a few seconds. The M2A1 features fixed headspace and timing, which eliminates the need to manually calibrate the weapon after each barrel change and reduces exposure time to enemy fire," said Mike O'Brien, vice president and general manager of gun systems for General Dynamics Armament and Technical Products. "The M2A1 is an efficient and reliable tool for American war fighters in combat".
