In the mid 1960s, Crouch sold his design to the High Standard Manufacturing Company, who used their C1200 Supermatic shotgun as the basis for the first model, the 10A. The C1200 Supermatic was modified by replacing the stock, relocating the trigger assembly, and fitting a three-piece plastic shell around the receiver and first half of the barrel. The rearward piece of the shell provided an attachment point for the rotatable shoulder stock. The lower piece of the shell provided the grip. Since the trigger assembly was moved forward to accommodate the bullpup design, a rod that connected the new and original trigger locations was used to allow minimal modifications to the original receiver.
High Standard Model 10A
Although the standard capacity of the Model 10 is 4 shells, there was a magazine tube extension available which would increase the capacity to 6 shells.
On the early model shotgun the 10A, the upper plastic section also housed the built-in flashlight and carrying handle.
The later model shotgun the 10B was improved with a left-hand charging handle, flip-up front sight, and utilized the new flashlight mount/carrying handle mounting block (which doubles as the carrying handle mount) as the rear sight. The "Kel-Lite" branded flashlight can be removed, as it is attached to the aforementioned mounting block.
Service
Originally, the Model 10 was sold to law enforcement only. The concept of this shotgun was quite interesting to many police agencies who adopted the Model 10 in the late 1960s and early 1970s; however, most of the agencies found many shortcomings, and ultimately ceased using the Model 10.
The most common problem was the failure to cycle correctly. According to the instructions on the Model 10, only magnum or "high brass" shells were to be used. However, even with the correct shells, the action would sometimes fail to cycle reliably. Other problems that plagued the shotgun were the rough and unpredictable trigger feel, the strange rotatable shoulder stock, and the tendency of the recoil to cause the flashlight's batteries to become damaged.
Another problem was that the Model 10 could only be fired from the right arm, as the gun ejected spent cartridges from the right side of the unit with a high force. There is a warning on the right side of the shotgun reading "CAUTION - DO NOT SHOOT FROM LEFT SHOULDER."
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and used by an individual. The term is legally defined further in different countries.
The Pancor Corporation Jackhammer is a 12-gauge, blow-forward gas-operated bullpup automatic shotgun designed in 1984 and patented in 1987. Only three working prototypes of the Jackhammer were built.

The Winchester Model 1897, also known as the Model 97, M97, Riot Gun, or Trench Gun, is a pump-action shotgun with an external hammer and tube magazine manufactured by the Winchester Repeating Arms Company. The Model 1897 was an evolution of the Winchester Model 1893 designed by John Browning. From 1897 until 1957, over one million of these shotguns were produced. The Model 1897 was offered in numerous barrel lengths and grades, chambered in 12 and 16 gauge, and as a solid frame or takedown. The 16-gauge guns had a standard barrel length of 28 in (71 cm), while 12-gauge guns were furnished with 30 in (76 cm) barrels. Special length barrels could be ordered in lengths as short as 20 in (51 cm) or as long as 36 in (91 cm). Since the time the Model 1897 was first manufactured, it has been used to great effect by American military personnel, law enforcement officers, and hunters.
The Mossberg 500 (M500) is a series of pump action shotguns manufactured by O.F. Mossberg & Sons.

Its compact bullpup design includes a telescopic sight, a non-adjustable fixed notch and front blade secondary sight. The weapon has fully ambidextrous controls, allowed by a unique ejection system, ejecting spent cartridge casings forward and to the right side of the weapon, through a tube running above the barrel. The F2000 made its debut in March 2001 at the IDEX defence exhibition held in Abu Dhabi, in the United Arab Emirates.
The lock of a firearm is the mechanism used to initiate firing. It is a historical term, in that it generally refers to such mechanisms used in muzzle-loading and early breech-loading firearms. Side-lock refers to the type of construction, in which the individual components of the mechanism are mounted either side of a single plate. The assembly is then mounted to the stock on the side of the firearm. In modern firearm designs, the mechanism to initiate firing is generally constructed within the frame or receiver of the firearm and is referred to as the firing or trigger mechanism.
The Saiga-12 is a shotgun available in a wide range of configurations, patterned after the Kalashnikov series of rifles and named after the Saiga antelope native to Russia. Like the Kalashnikov rifle variants, it is a rotating bolt, long-stroke gas piston operated firearm that feeds from a square magazine. All Saiga-12 configurations are recognizable as Kalashnikov-pattern guns by the large lever-safety on the right side of the receiver, the optic mounting rail on the left side of the receiver and the large top-mounted dust cover held in place by the rear of the recoil spring assembly. Saiga firearms are meant for civilian domestic sale in Russia, and export to international markets.
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock, or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body.
The Type 95 automatic rifle or QBZ-95 is a bullpup assault rifle designed and manufactured by Norinco, and issued since 1995 as the service rifle for the People's Liberation Army, People's Armed Police and various paramilitary law enforcement agencies in the People's Republic of China. The rifle's designation "QBZ" stands for "'light weapon' —'rifle' (Bùqiāng)—'automatic' (Zìdòng)", in keeping with the coding standards of the Chinese defense industry.
The A-91 is a bullpup assault rifle developed during the 1990s by KBP Instrument Design Bureau in Tula, Soviet Union as an offspring of the 9A-91 firearm family.
Break action is a type of firearm action in which the barrel(s) 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-barreled shotguns, double-barreled rifles, combination guns, and are commonly found in single shot pistols, rifles, shotguns, including flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions.
The Vepr is the first Ukrainian-made assault rifle, designed in 1993–1994 by the State Space Agency of Ukraine and announced in 2003. It is one of several bullpup conversions of the conventional Russian AK-family design, along with the Polish Kbk wz. 2005 Jantar, the Chinese Norinco Type 86S, the Russian OTs-14 Groza, the Finnish Valmet M82 and the South African Vektor CR-21.
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun which needs to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols, although other handguns such as derringers and machine pistols also see infrequent usage.
