Lever action in the context of Fully automatic

A shotgun (also known as a scattergun, peppergun, or historically as a fowling piece) is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot, or a single solid projectile called a slug. Shotguns are most commonly used as smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting sabot slugs (slug barrels) are also available.

Shotguns come in a wide variety of calibers and gauges ranging from 5.5 mm (.22 inch) to up to 5 cm (2.0 in), though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single barreled, double barreled, or in the form of a combination gun. Like rifles, shotguns also come in a range of different action types, both single-shot and repeating. For non-repeating designs, over-and-under and side-by-side break action shotguns are by far the most common variants. Although revolving shotguns do exist, most modern repeating shotguns are either pump action or semi-automatic, and also fully automatic, lever-action, or bolt-action to a lesser extent.

The Henry repeating rifle is a lever-action tubular magazine rifle. It is famous for having been used at the Battle of the Little Bighorn and having been the basis for the iconic Winchester rifle of the American Wild West.

Designed and introduced by Benjamin Tyler Henry in 1860, the original Henry was a sixteen-shot .44 caliber rimfire breech-loading lever-action rifle. It was produced from 1860 until 1866 in the United States by the New Haven Arms Company. The Henry was adopted in small quantities by the Union in the American Civil War, favored for its greater firepower than the standard-issue carbine. Many later found their way West, notably in the hands of a few of the Sioux and Cheyenne in their defeat of George Armstrong Custer's U.S. Cavalry troops in June 1876.

A Winchester rifle is any of a series of lever action repeating rifles manufactured by the Winchester Repeating Arms Company. Developed from the 1860 Henry rifle, Winchester rifles were among the earliest repeaters. The Model 1873 was particularly successful, being marketed by the manufacturer as "The Gun That Won the West".

A semi-automatic rifle is a type of self-loading rifle that fires a single round each time the trigger is pulled while automatically loading the next cartridge. Such rifles were developed before World War II and were widely used throughout that war. Rifles are firearms designed to be fired while held with both hands and braced against the shooter's shoulder for stability. Externally similar shotguns can fire multiple pellets simultaneously through a smoothbore, while rifle barrels are rifled to spin-stabilize individual bullets. The actions of semi-automatic rifles use a portion of the fired cartridge's energy to eject the spent casing and load a new round into the chamber, readying the rifle to be fired again. This design differs from manually operated rifles such as bolt-action and lever-action rifles, which need to chamber a cartridge manually before firing again, and automatic rifles, which continue firing as long as the trigger remains depressed.
