.22 Long Rifle

The .22 Long Rifle rimfire (metric designation: 5.6×15mmR) cartridge is a long-established variety of ammunition, and in terms of units sold is still by far the most common in the world today.

The cartridge is often referred to simply as .22 LR ("twenty-two-/ˈɛl/-/ˈɑːr/") and various rifles, pistols, revolvers, and even some smoothbore shotguns have been manufactured in this caliber. The cartridge originated from the Flobert BB cap of 1845 through the .22 Smith & Wesson cartridge of 1857, and was developed by the American firearms manufacturer J. Stevens Arms & Tool Company in 1887 by combining the casing of the .22 Long with the 40-grain (2.6 g) bullet of the .22 Extra Long. For many decades, it has been a very popular cartridge around the world. It is one of the few cartridges that are accepted by a large variety of rifles, as well as pistols. The .22 Long Rifle and related cartridges (.22 Short, .22 Long, and .22 Extra Long) use a heeled bullet, which means that the bullet is the same diameter as the case, and has a narrower "heel" portion that fits in the case.

Year 22 (XXII) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Agrippa and Galba (or, less frequently, year 775 Ab urbe condita). The denomination 22 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Heckler & Koch HK416

The Heckler & Koch HK416 (HK M4) is an assault rifle/carbine designed and manufactured by Heckler & Koch. It is based on the AR-15 platform, and was originally conceived as an improvement based on the Colt M4 carbine family issued to the U.S. military, with the notable inclusion of an HK-proprietary short-stroke gas piston system derived from the Heckler & Koch G36.

History

The United States Army's Delta Force, at the request of R&D NCO Larry Vickers, collaborated with the German arms maker Heckler & Koch to develop the new carbine in the early 1990s. During development, Heckler & Koch capitalized on experience gained developing the Bundeswehr's Heckler & Koch G36 assault rifle, the U.S. Army's XM8 rifle project (cancelled in 2005) and the modernization of the British Armed Forces SA80 small arms family. The project was originally called the Heckler & Koch M4, but this was changed in response to a trademark infringement suit filed by Colt Defense.

Delta Force replaced its M4s with the HK416 in 2004, after tests revealed that the piston operating system significantly reduces malfunctions while increasing the life of parts. The HK416 has been tested by the United States military and is in use with some law enforcement agencies and special operations units. It has also been adopted as the standard rifle of the Norwegian Armed Forces.
