A revolver is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers for firing. Because most revolver models hold up to six cartridges, before needing to be reloaded, revolvers are commonly called six shooters.
A semi-automatic rifle is an autoloading rifle that fires a single cartridge with each pull of the trigger, and uses part of the fired cartridge's energy to eject the case and load another cartridge into the chamber. In contrast, a bolt-action rifle requires the user to cycle the bolt manually before they can fire a second time, and a fully automatic rifle fires continuously until the trigger is released.
The scout rifle is a conceptual class of general-purpose rifles defined and promoted by Jeff Cooper in the early 1980s that bears similarities in the design and functionality of guide guns, mountain rifles, and other rifle archetypes, but with more emphasis being placed on comfortable portability and practical accuracy, rather than firepower and long range shooting.
In firearms terminology, an action is the functional mechanism of a breech-loading firearm that handles the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock.
The Colt AR-15 is a lightweight, magazine-fed, gas-operated semi-automatic rifle. It is a semi-automatic version of the M16 rifle sold for the civilian and law enforcement markets in the United States. The AR in AR-15 stands for ArmaLite rifle, after the company that developed it in the 1950s. Colt's Manufacturing Company currently owns the AR-15 trademark, which is used exclusively for its line of semi-automatic AR-15 rifles.
Smith & Wesson Brands, Inc. (S&W) is an American firearm manufacturer headquartered in Maryville, Tennessee, United States.
A semi-automatic firearm, also called a self-loading or autoloading firearm, is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, each trigger pull only discharges a single round from a semi-automatic weapon, as opposed to a fully automatic weapon, which will shoot continuously as long as the ammunition is replete and the trigger is kept depressed.
.22 Short is a variety of .22 caliber (5.6 mm) rimfire ammunition. Developed in 1857 for the first Smith & Wesson revolver, the .22 rimfire was the first American metallic cartridge. The original loading was a 29 or 30 gr bullet and 4 gr of black powder. The original .22 rimfire cartridge was renamed .22 Short with the introduction of the .22 Long in 1871.
The Smith & Wesson Model 500 is a five-shot, double/single action large-caliber revolver produced by Smith & Wesson, firing the .500 S&W Magnum cartridge.
A rim is an external flange that is machined, cast, molded, stamped, or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called "flanged" cartridges. Almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as "rimless cartridges". The rim may serve a number of purposes, including providing a lip for the extractor to engage, and sometimes serving to headspace the cartridge.

The .30 Remington AR is a cartridge created in 2008 by Remington Arms to fill a perceived gap in performance on large game between the .223 Remington and larger cartridges such as the .308 Winchester. The design of the cartridge is considered a joint effort between companies under the "Freedom Group" name through a private equity firm and included such companies as Bushmaster, DPMS and Remington itself. It is a rebated rim cartridge designed to fit Remington's R-15 semiautomatic hunting rifle. It was made to fit the dimensional constraints of the AR-15 magazine and is based on a modification of the .450 Bushmaster, which in turn is based on the .284 Winchester.

An AR-15–style rifle is any lightweight semi-automatic rifle based on or similar to the Colt AR-15 design. The Colt model removed the selective fire feature of its predecessor, the original ArmaLite AR-15, itself a scaled-down derivative of the AR-10 design by Eugene Stoner.
A cadet rifle is a rifle used by military cadets and others for basic firearms and marksmanship training. Generally .22 caliber and bolt-action, they also come in semi-automatic versions. They are often miniature .22 caliber versions of standard issue service rifles.
An AR-22 rifle is the general name given to an AR-15 rifle that can shoot 22lr rounds instead of 5.56 NATO rounds. An example of such a weapon available commercially would be the Smith & Wesson M&P15-22. A popular option is a conversion kit and alternate magazines for existing AR-15 rifles. In this vein, some manufacturers sell converted upper receivers as "AR-22" or similar.
