M240 Refile

Army and Weapons | M240 Refile | M240 was adopted by the U.S. military in 1977. The M60E4 (Mk 43 set by the U.S. Navy) was pitted against the (then called) M240E4 the Army trials in the 1990s for infantry medium machine gun new, in the competition to replace the decades M60s. M240E4 win, and then classified as the M240B. This led to 1000 existing M240 sent to FN for repairs and a special kit that modified them for use on ground (such as stocks, rails, etc.). This led to procurement contracts in the late 1990s for all-new M240B.

 

However, new features are added, hydraulic buffer system to reduce fear as incorporated in the M60. While the M240B had been more reliable in the tests, it's a few pounds heavier than the M60E4, and there is a program underway for a new medium-light machine guns in the early 2000s. The Army M240 converted M240B configuration should not be confused with a large number M240D converted into M240G configuration for the Marine Corps.

Clearing the weapon is done by ensuring the bolt locked to the rear and the weapon is on safe. Feed tray cover is then lifted, the remaining belt (if any) are swept out of the feed tray, the feed tray is lifted to visually inspect the back of the barrel and bolt face. Any links or brass casings removed. The weapon is now clear. In the rare event that the cycle of life is on the bolt face, knocking it loose with a cleaning rod or another rigid object. If there is a live round lodged in the barrel, the operator must immediately decide if the barrel is hot enough that there was a chance to cook off. If anything, he will immediately move his face away from the opening gun. 

 

He then had to wait for the barrel to cool before attempting to remove it. In many cases, attempting to remove the barrel will cause the round to detonate as soon as the barrel is opened by the recipient. Operators can also try to extract the round by taking the weapon off of safe, pulling the trigger and pull back on the charging handle. It has a fair chance of causing a firearm, so care must be taken to ensure that the weapons are pointed toward safe first.

Bullpup Rifle

 

Army and Weapons | Bullpup Rifle | Bullpup configuration weapons are where the action (or mechanism) and magazine are located behind the trigger. This increases the barrel length relative to the overall length of the weapon, allowing the short to long-barreled guns of the same, saving weight and increasing maneuverability. This allows for a longer barrel guns alternatives of the same length, improving trajectory and effective range. This concept was first used in a bolt-action rifle as Thorneycroft carbine of 1901, and is known to have been applied to semi-automatic firearms in 1918 (6.5 mm French Faucon-Meunier semi-automatic rifle developed by Lieutenant Colonel

 

Armand-Frédéric Faucon, then in 1936 a bullpup pistol patented by the French Henri Delacre. A 7.62 mm caliber experimental assault rifle developed by Korovin in the Soviet Union in 1945. England have been considering the idea of ​​bullpup service rifle since 1944. Two designs, EM-1 and EM-2 which was developed by the British as a substitute for a separate pistol, submachine guns and shotguns. Bullpup design options is a must to maintain accuracy while keeping the overall length down. EM-2 was adopted by the British in 1951 as the world's first rifle (limited) service bullpup but was soon replaced by the adoption of the 7.62 x 51 mm NATO cartridge.

 

Bullpups began a major military weapons in the 1970's with the introduction of the Steyr AUG and FAMAS in Austria and France, respectively (AUG later became standard military rifle for the problem some other countries). In 1985, Britain followed suit with the introduction of the SA80. Today, bullpups are common in modern military weaponry, and make a substantial minority of military small arms.

 

Recently, Israel, Singapore, Iran, and China has adopted all bullpup rifle designed and manufactured locally. The F2000 can only be adopted by a number of countries. New bullpup rifle actually exceeded new-layout conventional military rifle designed and introduced in recent years. Some mention the increasingly urban nature of the war as a reason for their popularity increased, the short-term they become useful in CQC (close quarter combat).
