Types of Firearms

Assault rifles, like the popular AR-15, usually fire smaller bullets than handguns. But they’re capable of firing many more bullets without reloading, which makes them potentially more lethal. The AR-15 is the most popular assault rifle in the U.S., and was originally designed to give U.S. soldiers an advantage over Russian-made AK-47 rifles during the Vietnam War.

With fully automatic weapons, open-bolt operation allows air to circulate, cooling the barrel; with semi-automatic firearms, the closed-bolt operation is preferred, as overheating is not as critical, and accuracy is preferred.

Although the United States had developed the M2 Carbine, a selective-fire version of the M1 Carbine during WW2, the .30 Carbine cartridge was closer to a pistol round in power, making it more of a submachine gun than an assault rifle.

The fire lance (simplified Chinese: 火枪; traditional Chinese: 火槍; pinyin: huǒ qiāng) was a very early gunpowder weapon that appeared in 10th century China during the Jin-Song Wars. It began as a small pyrotechnic device attached to a spear-like weapon, used to gain a critical shock advantage right at the start of a melee.

A machine gun is a fully automatic mounted or portable firearm designed to fire bullets in rapid succession from an ammunition belt or magazine, typically at a rate of 300 rounds per minute or higher. Not all fully automatic firearms are machine guns.

China is credited with inventing both gunpowder and firearms but the matchlock was claimed to have been introduced to China by the Portuguese. Europeans refined the hand cannons that had arrived in Europe in the early 15th century and added the matchlock mechanism.

A tactical knife is perhaps the best self-defense weapon you can carry. In fact, within 20 feet. a knife can be more effective, and more deadly, than a gun. We really like the idea of carrying a knife as your personal defense weapon because knives have multiple uses, even outside of self-defense.

A rifle is a portable long-barrelled firearm designed for precision shooting, to be held with both hands and braced against the shoulder for stability during firing, and with a barrel that has a helical pattern of grooves ("rifling") cut into the bore walls.

2.1.1 Shotgun A shotgun is a firearm designed to be fired from the shoulder and designed to use the energy of the explosive in a fixed shotgun shell to fire through a smooth bore either a number of projectiles or a single projectile for each pull of the trigger.10 A shotgun subject to the NFA has a barrel

A submachine gun (SMG) is a magazine-fed, automatic carbine designed to fire pistol cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun.
