Delta Force replaced its M4s with the HK416 in 2004 after it was proven that the piston operational system greatly reduces malfunctions and increased the life of the parts. In factory testing, the HK416 fired 10,000 rounds in fully automatic mode without malfunctioning. The gun has been tested by the U.S military and is used by some law enforcement agencies. It was also adopted as the standard rifle for the Norwegian Armed Forces and the French Armed Forces. The cost is high, so this gun is not widely used.

3. Stoner AR-15


During the early 1950s, the ArmaLite company, a division of Fairchild Engine and Airplane Corporation of Hollywood, California, was working on a new assault rifle. Their chief engineer was Eugene Stoner whom many considered to be the most talented firearms designer since John Browning. His first attempt was the AR10.

Later, the focus was changed to the 22-caliber rifle and the AR-15 was born. Tests by the Infantry Board found the AR-15 to be much more reliable than the M14 in the development stages but Dr. Carten’s report stated that the AR-15 had not demonstrated sufficient technical merit and should not be developed by the Army. So the Ordnance Corps lost interest in the AR-15.

In 1959, ArmaLitesold the rights to the AR10 and AR15 to Colt, who marketed it to different miltary services throughout the world.

In 1960, Air Force General Curtis LeMay wanted to order 80,000 of the guns and eventually, the gun was retested and approved, and General LeMay got his AR-15s.

Stoner’s family, after his death, asserted that he was an avid skeet shooter and hunter and did not own an AR-15 because he intended it only for military use.

There are many variants available of this gun. A few are the M4, M-16 and the AR- 15. The place of origin of this gun is the United States Of America. The designs of all the variants are same, even the parts used are some, what differs is the accessories. There are versions that fire automatically and are used by military worldwide. The semi- automatic versions are also quite popular as assault-style civilian rifles worldwide.

2. M2HB 50-Caliber Machine Gun


Also known as “The Fifty” or “Ma Deuce”, this gun has been used more than any other machine gun. It is a .50 caliber and shoots 500 rounds per minute with accuracy at more than a mile. This gun was designed by John Browning in 1918. It was classified as a “heavy machine gun”. Production began in 1921. Its design allowed a single receiver to be turned into seven different variants by adding jackets, barrels or other components. About 94 years after its production, the 324th one made was found in an Army depot. It had never been overhauled, yet still shot perfectly.
The design is simple and the parts are quite durable and it has a wide variety of applications.

The M2 machine gun has been produced longer than any other machine gun. In fact, the M2 has been in use longer than any other firearm in U.S. inventory except the .45 ACP M1911 pistol, also designed by John Browning. The M2 has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was used during World War II, the Korean War, the Vietnam War, the Falklands War, the Iraq War, and the War in Afghanistan.

The current M2HB is being manufactured in the U.S. by General Dynamics and U.S. Ordnance for use by the U.S. government, and for allies through Foreign Military Sales.



The most powerful gun in the world was developed by the Belgian Fabrique Nationale company. The enormous length makes it rather bulky, but it was the most popular assault rifle in the 20th century. This gun is a favorite in 90 countries. It is accurate, durable and flexible.

The prototype was finished in 1946, introduced by its designers in 1951, and produced two years later. In countries where the rifle was used, the letters FAL became an acronym and is pronounced as one word instead of an abbreviation.

Germany adopted the FN FAL in 1956. FN was happy to accommodate the German special features but refused to sell Germany a manufacturing license. FN had no problems with selling manufacturing licenses and did with many nations. The company just did not trust the Germans only 11 years after the end of World War II. The Germans were adamant at producing the rifle in their country and eventually abandoned the FAL for political reasons.

One thing gun collectors should keep in mind is that many in American have purchased rifles that they believed to be FALs but found to be far from the quality of a true FN. The reality is that most of what is on the U.S. market may look like a FAL but does not function like a true FN FAL. These are usually made from discarded parts and, while FN did use interchangeable parts, building a FAL from new parts or used parts requires much expertise.

FN’s assemblers were true craftsmen had numerous parts at their disposal and decided which to use by subjective feel, like a custom rifle. If one part did not feel right, the worker substituted another one. Unless you have fired an FN FAL or a quality made version as made by DSA, you have not truly experienced the classic FAL.

This is a brief description of the most powerful guns ever made. There is much more information available for those interested in a particular one mentioned here. Some have quite an interesting story that this synopsis could not do justice to. If you are a gun enthusiast or interested in military history, you would probably enjoy reading more about some of these.
