Presumably the well-known bin Laden must have heard about it. He was once stabbed in the flesh in the eyes of the Americans and was eventually shot to death after the careful operation of the US Navy SEALs. I believe that many friends must think that the gun that killed Osama bin Laden must be a famous American gun. In fact, Osama bin Laden, who was shot to the head and chest by the HK416 automatic rifle, was very difficult to sell at the beginning, and almost no one cares about it. Described that although there are occasional small orders, most of the orders from law enforcement or security agencies, accidentally saw a US military use HK416 in Iraq, but it is estimated that it is also a personal act.

But there is an old saying that gold always shines. After difficult sales, HK416 began to usher in its own spring. In 2007, it finally got a good news. , First of all, in the March 1, 2007 report of the US "Army Times", the Delta Commando planned to purchase a batch of HK416 upper receivers, which will obviously be used to modify the existing M4A1. In the US Federal Procurement Announcement (No. FA5270-07-R0009) on March 28, it was shown that 84 sets of HK416 10-inch upper receiver sets were purchased for the 1st Special Forces battalion of "DELTAFORCE" in Ryukyu. use. The Jane’s report on April 25, 2007 stated that Norway had signed an order contract worth $16.6 million with the German HK company to purchase 8,200 HK416 and related accessories and spare parts for the replacement of existing Norwegian military equipment. G3 rifle. The selection of the new Norwegian gun also includes the HK company G36KV3 and the Canadian Dimark company C8, but I did not expect that the final contract will be the same as the HK company HK416. Obviously, the Norwegian believes that the reliability improvement is more important than the top-heavy man and machine. Efficacy is more important. The technology of HKM4 is not the first, and there are similar products with similar M16/M4 modified air guiding devices. In fact, Taiwan T65 can be regarded as a similar product of M16+AR18 air guide device. Although the steel magazine of HK416 is relatively heavy, it has high reliability. Therefore, the US Department of Defense has ordered a batch of HK416 magazines to replace part of M16 aluminum magazines. .

HK416 actually has another name "HKM4". HK416, originally produced in Germany, was developed by Heckler & Koch (often abbreviated as H&K or HK), and is now produced in the United States. The British SA80 and M16 were modified by the HK company. The HK 416 was developed to provide a weapon with better performance than the long-serving M16 assault rifle. It uses a short-stroke air-guided automatic method, instead of using a direct air drive system like the M16 series. The gun has made significant improvements to the basic design of the M16, replacing the integrated alloy front bracket with a two-part polymer front bracket and adopting a floating barrel. Equipped with a foldable mechanical sight, because the standard configuration uses optical and night vision sighting equipment.
On February 11, 2004, at the gun show held in Las Vegas, the HK company exhibited several new products, in addition to XM8 and P2000SK, there is also a kind of collectively known as "HKM4" (Note: It is not HK's "M4", but the "HKM4" ) carbine series products. This weapon is actually a modification of the M16 series of rifles, named HKM4 instead of HKM16 probably because the name M4 has more commercial value. Later, it may be because Colt planned to sue HK Company for infringing their rights in 2004. HK Company gave up the name HKM4 and changed its name to HK416. "4" probably refers to M4, and "16" probably refers to M16. The HK416 was officially launched on the market in February 2005. At the same time, a new structure of Picatinny rail handguard was adopted, which makes the HK416 and the original M16/M4 carbine more distinct in appearance.

And the performance of HK416 is also very good, if it does not come later, it will not be purchased by the US special forces, HKM4 Reliability tests conducted at the U.S. Army’s ground weapons proving ground in the Yuma Desert in Arizona, under a variety of extreme environments, as demonstrated by different types of barrels, different types of ammunition, and installation or absence of mufflers. The reliability is higher than that of the M16 series, and it can even be shot underwater. As long as the guns of the same level of the US military M4A1-CQBR and M16A4 are flooded, they will explode. "The HK416 has no problem at all, and there is almost no heat and gunpowder gas (dirt) transmitted to the gun when shooting. This AR gun series (M16, M4, etc.) is unmatched.

as a derivative of the M4 carbine, there are also many similarities and differences between the appearance of the two.
①The “safety”, “semi-auto” and “auto” of the insurance selector button use the international icons; ②redesign the telescopic butt, and the bottom plate of the butt can be rotated; ③redesign the grip to improve the grip; ④The integrated tactical fishbone handguard adopts a floating design. The main internal difference is the short-stroke piston transmission system of the HK G36. In order to withstand the pressure brought by the new transmission system, the barrel wall is also thicker. In addition, the adjustable piston system makes the short barrel module (with or without muzzle silencer) more reliable. The mechanical sight is a folding front sight with a rear sight similar to G3. Most parts of HK416 are made of stainless steel, while M16 and M4 series are mainly made of aluminum alloy and plastic. Remove the upper receiver from the HK416 to directly access the M4 system. In other words, you can directly install the HK416 transmission system, handguards, and sights with the lower receiver of the existing AR-15 gun.
In general, the performance of HK416 is quite good. Before G36, almost all automatic weapons of HK company adopted roller lock. After G36, almost all firearms of HK company also adopted AR-18 air guide device. . HK company engineers will indeed use mature technology. In any case, this new type of air guide is more reliable than the M16 series, which is prone to "dirty", and can greatly reduce the user's maintenance. In order to increase the service life, HK company uses high-quality European steel to manufacture 5 different lengths of cold forged barrels, including 9 (HK416C), 10 (10.4) (HK416D), 14.5 (16.5) (HK416N) and 20 (HK416S) Inch, there is also a semi-automatic civilian MR556 (14.5 or 16.5 inch barrel). The life of the cold forged barrel is more than 20,000 rounds. It can shoot 3000 rounds in one maintenance. There are currently 5 barrels of different lengths. In addition, a new buffer device is used to improve the reliability and safety of the weapon. In addition, a more reliable steel magazine was manufactured (with empty storage). It can also be seen from the picture above that HK has also improved the new firing mechanism. The position of the speed machine (standard speed machine is single shot burst, fully automatic and locked three gears, and can be operated by left and right hands) is much more convenient than the M16 series. . Makes HK416 more perfect and outstanding.
