GUNS LOTS OF GUNS

  HK416 Rifle System Caliber :　 5.56 × 45mm NATO At the 2004 Gun Show held in Las Vegas, USA on February 11, HK exhibited several new products. In addition to the XM8 and P2000SK, there was also a series of carbines collectively called "HKM4" (note: not HK's "M4", but "HKM4") . This weapon is actually a modification of the M16 series rifles. It was named HKM4 instead of HKM16 probably because the name M4 has more commercial value. At that time, many companies produced and sold rifles with similar appearance and names to M4, which made Colt extremely dissatisfied.

However, HK IAR is the lightest among all competing models, weighing 7.9 pounds (about 3.6kg) when empty, and the operation is the same as M16 . Ordinary soldiers do not need special training to master it, because HK simply directly took out one of the carbine models of HK416 to participate in the bidding. According to the Marine Corps Times on December 2, 2009 , HK IAR won the bid in this project. In May 2010, HK IAR was officially designated as M27 and has begun to be delivered to troops for trial. The Marine Corps does not require the IAR to have a quick barrel replacement function. The US military has always believed that machine guns must be able to...
