The Springfield Model 1866 was the second iteration of the Allin-designed trapdoor breech-loading mechanism. Originally developed as a means of converting rifle muskets to breechloaders, the Allin modification ultimately became the basis for the definitive Springfield Model 1873, the first breech-loading rifle adopted by the United States War Department for manufacture and widespread issue to U.S. troops.

The Model 1866 corrected problems encountered with the prototypical Springfield Model 1865, in particular a simplified and improved extractor and a superior .50 caliber centerfire cartridge (the Model 1865 used a .58 caliber rimfire cartridge with mediocre ballistics), among many other less significant changes. It employed a robust version of the trapdoor breechblock design originated by Erskine S. Allin, Master Armorer of the Springfield Armory.

Approximately 25,000 .58 caliber Springfield Model 1863 rifled muskets were converted by Springfield Armory for use by U.S. troops, the barrels being relined and rifled to .50 caliber and the trapdoor breech system affixed. The rifle was chambered for the powerful centerfire .50-70 Government cartridge (.50 caliber 450-grain (29 g) bullet; 70 grains (4.5 g) of black powder). Though a significant improvement over the extractor of the Model 1865 Springfield Rifle, the Model 1866 extractor was still excessively complicated and the extractor spring was somewhat prone to breakage. However, it is a misconception that a broken extractor disabled the weapon. In the official 1867 government user booklet “Description and Rules for the Management of the Springfield Breech-Loading Rifle Musket, Model 1866”, the following is stated regarding a broken extractor and/or ejector: “It should be understood that the ejector and friction springs are convenient rather than necessary, and that the piece is not necessarily disabled if one or both of them should break, for the shell can be easily removed by the fingers after being loosened by the extractor hook.” Furthermore, the cleaning rod of the rifle can be used quite effectively to remove a stuck case in an emergency. Thus it is clear that this weapon is not as easily disabled as is sometimes believed.

The Model 1866 was issued to U.S. troops in 1867, and was a major factor in the Wagon Box Fight and the Hayfield Fight, along the Bozeman Trail in 1867. The rapid rate of fire that could be achieved disrupted the tactics of attacking Sioux and Cheyenne forces, who had faced muzzle-loading rifles during the Fetterman massacre only a few months before. The new rifles contributed decisively to the survival and success of severely outnumbered U.S. troops in these engagements.

In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/belt-fed firearms, but also with much slower rates of fire.

The term Springfield rifle may refer to any one of several types of small arms produced by the Springfield Armory in Springfield, Massachusetts, for the United States armed forces.

The Remington M1867 is a rolling-block rifle that was produced in the second-half of the 19th century. It was the first rifle using metallic cartridges to be adopted by the Norwegian and Swedish armies. Nominally, it had a caliber of 4 decimal lines, but the actual caliber was 3.88 Norwegian decimal lines or 4.1 Swedish decimal lines (12.17 mm), and it fired a rimfire round with a 12.615 mm lead bullet. The 12.17 mm caliber was chosen because the Swedish army had approximately 30,000 new muzzle-loading M1860 and breech-loading M1864 rifles in 12.17 mm caliber in stock, rifles that were suitable for conversion to M1867 rolling-block rifles. With the exception of the first 10,000 rifles and 20,000 actions, which were made by Remington in the US, all Remington M1867 rifles and carbines were made under license in Norway and Sweden, by Kongsberg Vaapenfabrik in Norway, and by Husqvarna Vapenfabriks Aktiebolag and Carl Gustafs stads Gevärsfaktori in Sweden with the two Swedish manufacturers producing about 80% of the weapons.

A rifled musket, rifle musket, or rifle-musket is a type of firearm made in the mid-19th century. Originally the term referred only to muskets that had been produced as a smoothbore weapon and later had their barrels replaced with rifled barrels. The term later included rifles that directly replaced, and were of the same design overall as, a particular model of smoothbore musket.

The .45-70, also known as the .45-70 Government, .45-70 Springfield, and .45-21⁄10" Sharps, is a .45 caliber rifle cartridge originally holding 70 grains of black powder that was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873. It was a replacement for the stop-gap .50-70 Government cartridge, which had been adopted in 1866, one year after the end of the American Civil War, and is known by collectors as the "Trapdoor Springfield".

The Springfield Model 1873 was the first standard-issue breech-loading rifle adopted by the United States Army. The rifle, in both full-length and carbine versions, was widely used in subsequent battles against Native Americans.

The Springfield Model 1870 was one of the rifles which used the trapdoor breechblock design developed by Erskine S. Allin. The Model 1870 was a minor improvement to the Springfield Model 1868, and retained most of the Model 1868 rifle features.

The Springfield Model 1868 was one of the rifles which used the trapdoor breechblock design developed by Erskine S. Allin.

James Paris Lee was a British Canadian inventor and arms designer. He is best known for having invented the Lee Model 1879 rifle, which is the first bolt-action detachable box magazine-fed rifle. These features would be incorporated into more successful repeating rifle designs later on, such as in the Lee–Metford and Lee–Enfield rifle series.

The .50-70 Government / 12.7 x 45 mm R, also known as the .50-70 Musket, .50-70 Springfield, and .50-1+3⁄4" Sharps) is a black powder cartridge adopted in 1866 for the Springfield Model 1866 trapdoor rifle.

During the American Civil War, an assortment of small arms found their way onto the battlefield. Though the muzzleloader percussion cap rifled musket was the most numerous weapon, being standard issue for the Union and Confederate armies, many other firearms, ranging from the single-shot breech-loading Sharps and Burnside rifles to the Spencer and the Henry rifles - two of the world's first repeating rifles - were issued by the hundreds of thousands, mostly by the Union. The Civil War brought many advances in firearms technology, most notably the widespread use of rifled barrels.

The Springfield Model 1870 rolling-block U.S. Navy rifle was a shipboard small arm for use by the United States Navy, employing the Remington Arms Company rolling-block design, and manufactured under a royalty agreement with Remington.

The Springfield Model 1869 was one of several model "trapdoor Springfields", which used the trapdoor breechblock design developed by Erskine S. Allin.

Frank Wesson rifles were a series of single-shot rifles manufactured between 1859 and 1888 in Worcester, Massachusetts. They were purchased by many state governments during the American Civil War, including Illinois, Indiana, Kansas, Kentucky, Missouri, and Ohio.

In firearms, a trapdoor is a form of breech-loading mechanism for rifles in which a hinged breechblock rotates up and forward, resembling the movement of a trapdoor. The Springfield models 1865 and 1873 were best known for first employing this type of action.

The Serbian Peabody rifle is a single-shot breech-loading rifle made and used in the Principality of Serbia in the second half of the 19th century. It was the first Serbian military rifle to use metallic cartridges.
