What is the difference between M4A1 and M6? What is the difference between M16 and M4

m6？m16 bar.

The one above has copied so much, in fact, two sentences can explain it.

The M4 is a short-barreled automatic rifle (carbine) developed on the basis of the M16A2 automatic rifle, and the M4A1 is an improved version of the M4.

Carbine originally meant a carbine, that is, a rifle used by a rider, usually with a shorter barrel.

1. The M16 is called an assault rifle and is mainly used by the ground forces of the US Army. It is the main battle equipment of the United States Army. The M4 is a carbine, which can be seen as a smaller version of the M16, which is mainly used by the US Navy, Air Force and Special Forces.

2. Appearance: The M16 barrel is relatively long, the muzzle velocity of the bullet is large, the firing range is slightly longer, and the power is greater; The M4 has a shorter barrel and a slightly shorter range, but because it is lightweight, it is generally distributed to US special forces, as well as naval or air force ground forces, for self-defense.

3. The M16 is an old-fashioned rifle (the improved A3 model can carry a filter), and cannot carry certain equipment, such as infrared sights, low-light night vision, etc. However, the M4 can be equipped with these equipment and provide various support for the US military's special operations.

4. M16 is an assault rifle with three shooting modes: single shot, triple burst fire and fully automatic. The M4 has only two modes: single and triple bursts.

5. The use environment and tactics are also different, mainly M16 is used in regular operations, and M4 is used in special operations or naval and air force reserves.

<> from an objective point of view, the M4A1 is an improved version based on the M16, the main thing is that it has been updated in terms of bullets and gunpowder, and it has also been shortened in length. However, the main differences between the two M4A1 and M16 are in the following aspects. First of all, in terms of status and significance, the M16 has a slight edge.

The M16 series automatic rifle is the second generation of rifles reequipped by the United States after World War II, which created a precedent for small-caliber and had a far-reaching impact on the miniaturization of light shouting false attacks in the future. Since it became the standard rifle of the U.S. Army in 1967, it has been used by nearly 100 countries.

In addition, it and its modified guns are also used in more than 50 national Zheng brothers' homes, in addition to the army, the M16 series has also been adopted by many SWAT teams, private security agencies, non-** guerrillas and other organizations, known as one of the six famous guns in the world today.

The M4A1 carbine is a rifle developed by the Colt company, which is the first modification of the M4 rifle, which mainly designs a new flat-top receiver cover to facilitate the installation of a modular sighting system. to meet the needs of indoor hand-to-hand combat**.

In addition, the M16 is a rifle and the M4A1 is a carbine, and when the two guns are put together, it is obvious that the M4A1 is a little more compact and has a shorter barrel than the M16. In addition, the M4A1 has a retractable stock, and although some of the M16 series rifles are retractable, its stock is not adjustable.

In terms of performance, the M16 is an improvement from the AR-15, with a total gun length of 986 mm, a caliber, a theoretical rate of fire of 700-950 rounds, and a muzzle velocity of the warhead capable of reaching 975 meters per second.

And the M4A1 belongs to a new type of M16 carbine and is equipped with a large number of tactical accessories. The barrel length is about the same, the caliber is the same, and it can theoretically reach a rate of fire of 800-980 rounds in one minute, and the muzzle velocity of the warhead is about 884 meters per second. See that the M4A1 has an advantage in the rate of fire, but in terms of accuracy and power, the M16 is even better!

Moreover, the operational needs of the two are different. The M16 is an infantry assault rifle with a longer barrel and greater power and range, but with fewer auxiliary accessories, mainly for infantry ground combat use. The M4 is a carbine with a short barrel and accessories such as nylon rails, which are generally issued to special forces and other units that operate in small spaces.

It is more suitable for special operations, close-range fire suppression, and tactical equipment can be adapted to the needs of different missions; The M16 is more suitable for medium and long-range shooting, and the cost is cheap and suitable for large-scale equipment. However, the distance of combat in modern warfare has been greatly reduced, so such a long-range reputation will appear excessive.

M4 is used for close-range street fighting, such as the installation of ACOG, M203, night vision devices, etc. Therefore, in the Iraq war, the Iraqi army suffered a great loss in the night battle with the US military. The M16 uses a heavy barrel and has a long body, which is very inconvenient for tank members and pilots to carry, because the M16 has a fixed stock, but the M16 has a longer range than the M4.

M4 refers to the American M4 carbine, the United States Carbine Caliber, caliber NATO M4A1 (United States & North Atlantic Treaty Organization caliber M4A1 carbine).

The M16 is a second-generation rifle reequipped by the United States after World War II, which has had a profound impact on the later light miniaturization. To date, the M16 series rifle is used by nearly 100 countries and is known as one of the six most famous guns in the world today.

The recoil of the M4 is significantly smaller, more accurate, and more expensive.

The design of the M4 carbine dates back to the M16, an earlier carbine version. They were all developed from the CAR-15 developed by Eugene Stoner, and the M4 was shorter in length and lighter than the M16A2 assault rifle, and eighty percent of the parts could be shared. Some M4A1s are fitted with thicker and heavier barrels to reduce the heat generated during fully automatic** and thicker aluminium insulation.

All M4 and M4A1 use SS109 bullets, and still use the M16's unique gas direct thrust transmission. The M4A1 carbine is also used by the Multinational Counter-Terrorism Force (TNT) and the SWAT Force, mostly in close combat. It is also very suitable for urban warfare.

The M4 is a carbine, and the M16 is an assault rifle.

The M4 is a carbine version of the M16.

The M4 has a shorter barrel and a shorter firing range. However, the M4 has a fully automatic firing mode, while the M16 except for the M16A3 version, other versions of the M16 cannot be fully automatic, and can only shoot semi-automatically, or in triple burst mode. The M4 is fully automatic.

Therefore, from the point of view of use, the M16 is used by the army field army, and it has high long-range accuracy, but poor firepower. The M4 is equipped with special forces or airborne troops, and has strong firepower, but its long-range accuracy is not as good as that of the M16
