A revolver is a repeating handgun with at least one barrel and 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 or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns.
A semi-automatic rifle is an auto-loading rifle that fires a single round of ammunition at a time, contained in a cartridge, with each pull of the trigger. It uses part of the fired cartridge's energy to eject the case and automatically loads another cartridge into its chamber. This is in contrast to bolt-action or lever-action rifles, which require the user to manually chamber a new round before they can fire again, and fully automatic rifles, which fire continuously while the trigger is held down.
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 breechloading 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 product line of magazine-fed, gas-operated, autoloading rifle manufactured by Colt's Manufacturing Company ("Colt") in many configurations. The rifle is a derivative of its predecessor, the lightweight ArmaLite AR-15, an automatic rifle designed by Eugene Stoner and other engineers at ArmaLite in 1956.
A bullpup firearm is one with its firing grip located in front of the breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable, and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range, and ballistic effectiveness.
Smith & Wesson Brands, Inc. (S&W) is an American firearm manufacturer headquartered in Maryville, Tennessee, United States.
.22 short is a variety of .22 caliber 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.
Rotating bolt is a method of locking the breech of a firearm closed for firing. Johann Nicolaus von Dreyse developed the first rotating bolt firearm, the "Dreyse needle gun", in 1836. The Dreyse locked using the bolt handle rather than lugs on the bolt head like the Mauser M 98 or M16. The first rotating bolt rifle with two lugs on the bolt head was the Lebel Model 1886 rifle. The concept has been implemented on most firearms chambered for high-powered cartridges since the 20th century.
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 Heckler & Koch SL8 is a semi-automatic rifle manufactured by Heckler & Koch. It is a civilian version of the Heckler & Koch G36.
The Smith & Wesson K-22 Target Masterpiece Revolver is a six-shot, double-action revolver with adjustable open sights, built on the medium-size "K" frame. When introduced, it was intended for bullseye target shooting competition of the type then most common on the United States, which is today called NRA Precision Pistol, specifically in the "smallbore" or "22" category. It is chambered for the .22 Long Rifle cartridge. It is one of three similar models that Smith & Wesson offered, the other two being intended for the "centerfire" category, the K-32 Target Masterpiece chambered for the .32 S&W Long cartridge and the K-38 Target Masterpiece chambered for the .38 Special cartridge. Most K-22 revolvers were fitted with a 6 in (150 mm) or 8+3⁄8 in (210 mm) barrel, but other lengths have been produced. First produced in 1947 and originally known as the K-22 Target Masterpiece, it was numbered the Model 17 in 1957 when all Smith & Wesson guns were given numerical model numbers. It is built on the same frame as the seminal Smith & Wesson Model 10 revolver.
The .30 Remington AR / 7x39mm Remington AR is an intermediate 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.
The Remington Model 8 is a semi-automatic rifle designed by John Browning and produced by Remington Arms, introduced as the Remington Autoloading Rifle in 1905, though the name was changed to the Remington Model 8 in 1911.
The SR-556 is a semi-automatic AR-15 style rifle manufactured by Sturm, Ruger & Co. The rifle was introduced in 2009 in .223 Remington/5.56×45mm NATO and as a .308 Winchester AR-10 variant in 2013, the SR-762. It is one of several AR-15 rifles to use a gas piston operation.

The 7.62×40mm Wilson Tactical is a centerfire rifle cartridge introduced in 2011 by Wilson Combat. The goal was to produce an accurate, low-recoil .30-caliber hunting cartridge that could be used in an AR-15-type rifle using as many standard components as possible.
An AR-15–style rifle is a 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, which is a scaled-down derivative of the AR-10 design. It is closely related to the military M16 rifle.
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.
