Rolling Block
A rolling block action is a form of firearm action where the sealing of the breech is done with a specially shaped breechblock able to rotate on a pin. The breechblock is shaped like a section of a circle. The breechblock is locked into place by the hammer, thus preventing the cartridge from moving backwards at the moment of firing

Breech-loading Weapon
A breech-loading gun is a firearm in which the cartridge or shell is inserted or loaded into a chamber integral to the rear portion of a barrel. Modern mass production firearms are breech-loading (though mortars are generally muzzle-loaded), except those which are intended specifically by design to be muzzle-loaders, in order to be legal for certain types of hunting. Early firearms, on the other hand, were almost entirely muzzle-loading. The main advantage of breech-loading is a reduction in reloading time – it is much quicker to load the projectile and the charge into the breech of a gun or cannon than to try to force them down a long tube, especially when the bullet fit is tight and the tube has spiral ridges from rifling

Springfield model 1871
rolling-block U.S. Army rifle was manufactured in 1871–72 by Springfield Armory, using the design originated by Remington Arms Company, under a royalty agreement.[1]Contents1 Origin 2 Production 3 See also 4 Notes 5 ReferencesOrigin[edit] During the U.S. Civil War, Joseph Rider experimented with several breech loading weapon designs. In 1865, he was issued the first patent for what would evolve into the Remington rolling block action.[2] The Remingtons continued to invest in Rider's work, and met with Ordnance Department officials in the hope of interesting them in this new design. The U.S. Navy Ordnance Department became interested in the design, and purchased several different models of rifles from 1867 through 1869

Bolt Action
Bolt action
Bolt action
is a type of repeater firearm action where the handling of cartridges into and out of the weapon's barrel chamber are operated by manually manipulating the bolt directly via a handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). As the handle is operated, the bolt is unlocked from the receiver and pulled back to open the breech, allowing the spent cartridge case to be extracted and ejected, the firing pin within the bolt is cocked (either on opening or closing of the bolt depending on the gun design) and engages the sear, then upon the bolt being pushed back a new cartridge (if available) is loaded into the chamber, and finally the breech is closed tight by the bolt locking against the receiver. Bolt-action firearms (or "bolt guns" colloquially) are most often rifles, but there are some bolt-action variants of shotguns and a few handguns as well

Lever-action
Lever action
Lever action
is a type of firearm action which uses a lever located around the trigger guard area (often including the trigger guard itself) to load fresh cartridges into the chamber of the barrel when the lever is worked. This contrasts to bolt-action, semi-automatic, or selective-fire weapons. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have also been made. One of the most famous lever-action firearms is the Winchester Model 1873 rifle, but many manufacturers—notably Marlin and Savage—also produce lever-action rifles. Even Colt's Mfg. Co. produced 1883 until 1885 6403 lever-action Colt-Burgess rifles. Mossberg produces the 464 in centerfire .30-30

Slide-action
A pump-action or slide-action firearm is one in which a forend can be moved forward and backward in order to eject a spent round of ammunition and to chamber a fresh one. It is much faster than a bolt-action and somewhat faster than a lever-action, as it does not require the trigger hand to be removed from the trigger while reloading. Once fired, the forend is slid rearward by hand and the expended cartridge ejected

Break-action
Break action
Break action
is a type of firearm action in which the barrel or barrels are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barrelled shotguns, double rifles and combination guns, and are also common in single shot rifles, pistols (especially derringers), and shotguns, and can also be found in flare guns, grenade launchers, air guns and some older revolver designs

Falling-block Action
A falling-block action (also known as a sliding-block or dropping-block action) is a single-shot firearm action in which a solid metal breechblock slides vertically in grooves cut into the breech of the weapon and is actuated by a lever.[1]Contents1 Description 2 See also 3 References 4 External linksDescription[edit]Sliding (falling) block action.When the breechblock is in the closed (top) position, it seals the chamber from the high pressures created when the cartridge fires and safely transfers the recoil to the action and stock. When the breechblock is in the lowered position, the rear (breech) end of the chamber is exposed to allow ejection or extraction of the fired case and reloading of an unfired cartridge. It is a very strong action; when the breech is closed, the receiver essentially becomes a single piece of steel (as opposed to other actions which rely on lugs to lock the breech)

Remington M1867
The Model 1867 Remington rolling block rifle was the first rifle using metallic cartridges to be adopted by the Swedish and Norwegian armies. Nominally it had a caliber of 4 decimal lines, but the actual caliber was 4.1 Swedish decimal lines or 3.88 Norwegian decimal lines (12.17 mm), and it fired a rimfire round with a 12.615 mm (.497 in) lead bullet. The 12.17 mm caliber was chosen because the Swedish army had approximately 30,000 new muzzle-loading Model 1860 and breech-loading Model 1864 rifles in 12.17 mm caliber in stock, rifles that were suitable for conversion to Model 1867 rolling block rifles

Firearm Action
In firearms terminology, an action is the mechanism that handles the ammunition (loads, locks, fires, extracts and ejects) or the method by which that mechanism works. Breech-loading weapons have actions; actions are technically not present on muzzleloaders, as all are single-shot weapons with a closed off breech. Actions can be categorized in several ways, including single action versus double action, break action versus bolt action, and others. The term action can also include short, long, and magnum if it is in reference to the length of the rifle’s receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of 2.8 in (71 mm) or smaller
