The SPAS 15 MIL (SPAS stands for Special Purpose Automatic Shotgun) is a purely military weapon, inheriting the mantle of the assault rifle in its design conception and construction, with combat effectiveness that meets the requirements of both the US and Italian militaries.
The gun is somewhat similar in appearance to the Belgian FNC assault rifle, and its internal structure is similar to that of a conventional rifle. It utilizes the gas-guided automatic principle, rotating the receiver to lock and unlock the chamber for firing, and is capable of semi-automatic and pump-action firing, which can be switched at any time by a button on the pump-action grip (wood guard).
The pump-action mechanism is the same as that of the common tubular magazine shotguns, and is designed to ensure the manual decocking and feeding of shells when the firing charge pressure is too weak.
The safeties are dual, with an unconventional manual safety knob on the front of the trigger guard (locking the trigger and hammer), which is automatically pushed to the firing position when the action pushes a round from the magazine into the chamber, a device that prevents the danger of the action improperly unlocking (latching out of place) during pump-action firing. There is also a grip-press safety at the front of the grip, which can only be depressed to release the trigger.
The receiver is stamped nickel-chrome steel with the outer surface shot blasted and phosphated. Above the receiver is a carry handle for a range of sighting devices, and below the handle is a pull handle that can be operated by either right or left hand. The barrel is made of high-strength molybdenum-chromium steel with a chrome-plated bore and phosphated exterior, and the muzzle is threaded to allow for screwing of the muzzle device.
The stock consists of two steel tubes and a bottom bracket that folds to the left.
The gun can be attached to a series of auxiliary devices at the muzzle, and is capable of firing a variety of super-caliber grenades, which is rare in shotguns, and indicates that this shotgun is quite close to an assault rifle.
The SPAS 15 MIL is a 12-gauge caliber that fires serialized military and police ammunition. The standard deer shot (a lead bullet) fired at a distance of 40 meters in the dispersion of 900 mm in diameter, even if the probability of aiming at the hit rate is also very high, the projectile 40 meters of survival energy than 7.65 mm pistol rounds at the same distance of the survival of the energy is also higher than 50%. Its launch of a single bullet and 7.62 mm NATO bullet terminal energy equivalent to the same caliber of tear gas and ultra-caliber grenades can reach a range of 150 meters. The gun weighs 3.9 kilograms empty, the whole gun length of 915 millimeters, feeding mode for the magazine (6-round) type.
U.S. XM1014 automatic shotgun
Due to the growing importance of urban combat weapons, all types of CQB weapons filled the U.S. military units, at the same time, in the face of this aspect of the military threat is also growing, and therefore take the lead in opening up the military use of tactical shotguns the U.S. military has decided to provide the army with new military shotguns, the proposed Tri-Service Tactical Shotgun Program ( Joint Service Combat Shotgun - JSCS), JSCS proposed technical indicators include: reliable semi-automatic firing mode, folding stock, and 76mm within all types of ammunition compatible with the structure of a solid. After comparative testing by the U.S. Army Ordnance Research, Development and Engineering Center, the XM1014 (commercially known as the M4 Super 90), a prototype provided by a joint company consisting of Burnelli and HK USA, stood out from the rest of the competition as a guided-gas semiautomatic shotgun, with a unique dual-piston system to ensure sufficient energy for low-temperature conditions. The chamber is 76mm long and can be used with 76mm or 70mm long shotgun shells. The top of the magazine has a RIS rail and can be equipped with a sighting system. The preferred standard accessory is the ACOG Reflex scope, and the M4 Super 90 has a unique telescopic stock that tilts to the right, making it easy to sight in with a gas mask.

The American "Olin" (Olin) Close Combat Assault Weapon System
The "Olin" Close Combat Assault Weapon System was jointly developed by Olin Corporation of the United States and HK Corporation of Germany. According to the requirements of the ammunition at that time, Olin developed a diameter of 19.5 mm, 76 mm long brass cartridge ammunition, the bullet containing 8 tungsten alloy ball projectiles, each weighing 3.1 grams, muzzle velocity of 538 m / s, 150 meters away from the 20 mm thick pine boards or 1.5 mm thick soft steel plate can be penetrated.
The German company HK developed a weapon with a shape somewhat like a rifle on the basis of this ammunition. The ammunition used for this gun cannot be used for civilian shotguns, but civilian 12-gauge ammunition can be used for training on this gun. The weapon can be fired semi-automatically and automatically, and because it uses specialized ammunition, it does not have a pump-action mechanism.
The most striking feature of the gun is the internal "floating" mechanism, as in the German G11 caseless rifle. Due to the high energy of the ammunition it fires, the "float" mechanism greatly reduces the perceived recoil of the shot, thus improving shot controllability. The gun has an all-plastic casing and is stockless. The muzzle can be fitted with an additional device (throat retraction) to change the firing density. The gun can be thrown from the left side by turning the receiver position by 180°, which makes it possible for left-handed people to maneuver the shot.
The gun is based on the tube-return automatic principle, with a closed chamber. The safety, fast and slow machines are located on both sides of the receiver above the trigger, and can be manipulated by both left and right hands. The carry handle is located above the receiver and has a single optical sight inside the tubular handle, which can also be converted to a rail-type sighting rib for generalized aiming. The pull handle is located below the handle and can be operated with either the right or left hand.
In addition to tungsten shotgun shells, the gun's main ammunition includes "000" deer shells and cluster arrow shells. Cluster arrows containing 20 small arrows, muzzle velocity of up to 900 m / s, in the 100-meter range can penetrate the U.S. steel helmet and light body armor.
The gun weighs 3.7 kilograms empty, 764 millimeters long, 10-round magazines, the theoretical rate of fire of 240 rounds / min, the effective range of 150 meters.
The U.S. "steam hammer" (Jackhammer) A2 combat shotgun
The gun is the U.S. Pancor (Pancor) company developed a very unique design, the use of the rifle's "no support" structure, with the help of a rotary chamber for ammunition, can be used. The gun was developed by Pancor in the United States. It is automatic with a forward-firing barrel, which is not common in light weapons. When firing, the pressure of gunpowder gas makes the barrel forward, and then by the spring action to return, driving the rotation of the rotating wheel and make the transmitter in the state of waiting to strike. This automatic method makes the barrel avoid being fastened together with the runner under the action of gunpowder gas when firing, so that the runner rotates smoothly to supply ammunition. This is a reliable way to realize the automation of the high rifling pressure runner.
The gun is both a feeder and a chambered runner, with a striped bulge on the outer wall, which cooperates with the automatic lever cam in the barrel assembly to enable the runner to rotate when the barrel returns to motion. The wheel is pre-loaded and sealed, painted with different colors to distinguish the type of ammunition, the wheel can be discarded after use.
The barrel and flamethrower, the reloading spring and the "automatic mechanism" are all made of high-strength steel, while the receiver, the transmitter, and the rotor are made of plastic. The wood guard also serves as a pull handle, after installing the rotor, pulling the wood guard can make the transmitter in the standby state. The butt part has a release standby lever, which can be released when there are bullets in the chamber, making it easy to carry and transport safely. The carry handle also serves as a rail-type (bridge-type) sight.
The Hammer A2 is capable of firing any standard 12-gauge ammunition. Panco is currently researching new principles of ammunition, aimed at the development of a series of ammunition dedicated to this gun, one of which has been developed, this bullet made of plastic shells, can be loaded with armor-piercing bullets, arrows, chemicals, rockets and other range-extending bullets in the field, very powerful, the shooting barrel must be locked to prevent damage to the automatic mechanism, and can only be manually single-shot shooting.
The gun weighs 4.57 kilograms, with a length of 525 millimeters, a capacity of 10 rounds of ammunition, a theoretical rate of fire of 240 rounds per minute, and commonly used ammunition such as standard deer ammunition.
