Kel-Tec KSG: The Shotgun That Makes All Other Tactical Shotguns Obsolete

A tactical or combat shotgun is a class of smooth-bore small arms, the representatives of which can be extremely effective in hitting fast-moving targets in fast-paced combat and confined spaces. Add to this a wide selection of ammunition: buckshot, shot, live and rubber bullets. Thanks to these features, shotguns have become a common weapon in the arsenals of military and police forces around the world. Kel-Tec KSG was able to bring a number of innovative and interesting solutions to a specific niche that made the shotgun legendary.

Description

The Kel-Tec ShotGun is a shotgun designed with a bullpup design, meaning the magazine is located behind the trigger. The main distinguishing feature of the KSG is the two tubular cartridge containers located under the barrel, parallel to it. In the basic version, each of them holds up to 7 rounds, and the total capacity of the shotgun reaches 14 (+1). This makes it one of the most multi-shot pump-action shotguns, since shotguns rarely boast a large ammunition capacity.

An ambidextrous safety button and loading through a window located at the bottom of the receiver allow the KSG to be used equally effectively from the right shoulder as well as the left. Spent cartridges are also discharged through the loading window. The KSG is equipped with a Picatinny rail mounting system above and below the barrel. On the shotgun you can install: open and collimator sights of various types, a tactical flashlight, a laser pointer, a handle block and other accessories.

Excerpt describing Kel-Tec KSG

– Qui etes vous? Pierre was silent because he was unable to utter words. For Pierre, Davout was not just a French general; for Pierre Davout, he was a man known for his cruelty. Looking at the cold face of Davout, who, like a strict teacher, agreed to have patience for the time being and wait for an answer, Pierre felt that every second of delay could cost him his life; but he didn't know what to say. He did not dare say what he said during the first interrogation; revealing one's rank and position was both dangerous and shameful. Pierre was silent. But before Pierre could decide on anything, Davout raised his head, raised his glasses to his forehead, narrowed his eyes and looked intently at Pierre. “I know this man,” he said in a measured, cold voice, obviously calculated to frighten Pierre. The cold that had previously run down Pierre's back gripped his head like a vice. “Mon general, vous ne pouvez pas me connaitre, je ne vous ai jamais vu…” “C’est un espion russe,” Davout interrupted him, addressing another general who was in the room and whom Pierre had not noticed. And Davout turned away. With an unexpected boom in his voice, Pierre suddenly spoke quickly. “Non, Monseigneur,” he said, suddenly remembering that Davout was a Duke. - Non, Monseigneur, vous n'avez pas pu me connaitre. Je suis un officier militia naire et je n'ai pas quitte Moscou. - Votre nom? – repeated Davout. - Besouhof. – Qu'est ce qui me prouvera que vous ne mentez pas? - Monseigneur! - Pierre cried out in a not offended, but pleading voice. Davout raised his eyes and looked intently at Pierre. They looked at each other for several seconds, and this glance saved Pierre. In this view, apart from all the conditions of war and trial, a human relationship was established between these two people. Both of them in that one minute vaguely experienced countless things and realized that they were both children of humanity, that they were brothers. At first glance for Davout, who only raised his head from his list, where human affairs and life were called numbers, Pierre was only a circumstance; and, not taking the bad deed into account on his conscience, Davout would have shot him; but now he already saw a person in him. He thought for a moment. – Comment me prouverez vous la verite de ce que vous me dites? – Davout said coldly. Pierre remembered Rambal and named his regiment, his last name, and the street on which the house was located. “Vous n'etes pas ce que vous dites,” Davout said again.

Operating principle

Reloading of the gun magazines in the KSG is manual, carried out by a pump-action mechanism through the forward-reciprocating sliding of the forend. The shotgun fore-end itself is made of high-strength plastic and is connected to the bolt through two metal rods. The barrel channel is locked by a swing-type combat cylinder and engages the bolt with the tail of the barrel.

Two tubular magazines located horizontally under the KSG barrel are responsible for feeding cartridges, but only one is used at a time. Which cartridges will be taken from is regulated by switching a special lever, which is located at the bottom of the shotgun box. This switch has three states: left, right and center position, which allows you to empty the chamber or quickly throw ammunition into it.

KSG magazine switch

The shotgun is loaded one cartridge at a time through a window located at the bottom of the KSG, between the teeth of the feed fork. The inserted ammunition will go into the magazine that the switch lever is currently pointing at. Each magazine, depending on the KSG modification, holds from 4 to 7 rounds.

The KSG is equipped with a Picatinny rail, allowing you to install the necessary equipment. One of the main and recommended by Kel-Tec representatives is the front handle. It is used to clearly control the movement of the forearm during reloading and protects the hand from accidentally hitting the muzzle during active reloading.

Shooting

Shooting from a Sub-2000 is something special. It was this feature that made me change my opinion about him, to be honest. Fans of pistol caliber carbines probably already understand what I mean. In addition, the rifle is very light. Together with a 30-round magazine, a belt, a flashlight and a red dot sight, it will weigh 3.2 kilograms.

By the way, a collimator sight will be very useful. The sight on the Sub-2000 is quite interesting. It is very visible. In addition, the rear sight folds and unfolds with the rifle. Sights are designed for maximum speed and fairly accurate shooting. However, it is worth understanding that this is a small-caliber weapon, so it fires quickly, but with some spread.

The Sub-2000 is exactly the rifle it should be. If I were clearing out a building with any more or less open spaces, I would take it. Of course, for short distances I would still choose a shotgun, however, the Sub-2000 has a number of advantages. The small size makes this weapon extremely convenient for confined spaces, in addition, the shooter can use an extended magazine, and the stability of this weapon, which is due to the length of the barrel, allows the Sub-2000 to be fired like a rifle.

We decided to shoot at about 100 yards and got about what we expected. In a video of us shooting in the rain, we hit bowling pins with little to no difficulty. It only took a few shots to zero in, and the extended barrel allows for very impressive results compared to a pistol.

At close range the Sub-2000 will surprise you. We shot faster and faster. Of course, the recoil will throw off your aim, but this is very easy to deal with. And if you have a collimator, then your advantage over the intended enemy becomes obvious.

Design

The bullpup layout allows you to minimize the size of the gun. This ensures the greatest comfort in using the shotgun in limited combat conditions. For example, on city side streets, in apartments or inside buses. Thanks to its weight and size, the KSG performs well in dynamic and active work, which is why it is valued by law enforcement agencies.

KSG with optics

Both ammunition containers are fixed in the receiver. Each allows you to load a shotgun with seven 12/70 cartridges or six 12/76 cartridges through a special window. This gives a total capacity of 15 rounds. Next to the loading and ejection window there is a magazine selector.

The shotgun is not equipped with a choke. The barrel has an internal and external diameter of 18.4 mm and 21.8 mm, respectively. Above it is a Picatinny rail. The union nut that secures the barrel in the muzzle panel can be replaced with a door breaking attachment. Around the barrel there is a KSG forend, which is also equipped with a 15 cm long Picatinny rail at the bottom. The forend travel during reloading is 10.4 cm.

The shotgun shoulder rest is entirely plastic, with the exception of the feed tray located at the back of the box. The shutter assembly is compact and small, with dimensions of 59, 18 and 27 mm. When locked, the force-controlled bolt stop moves upward from the bolt block and fits into grooves on the top side of the barrel. The ejector is located on the bottom of the bolt.

The design of the weapon is well thought out, so disassembling the KSG for cleaning and maintenance is not very difficult. It consists of the following steps. It is best to perform them in a horizontal position.

Kel Tec KSG design

Disconnecting the trigger (trigger mechanism):

1. Cock the forend.
2. Place the shotgun on the safety.
3. Press out the USM fixing pins and install them in the special holes.
4. After which you can raise the trigger.

The back of the head is knocked out without additional manipulation and removed from the receiver. After that, all that remains is to move the platform with the shutter to the rearmost position and remove it. This way, you can gain access to the barrel and partially clean the shotgun.

To further disassemble the weapon you will need certain tools. But it is also simple.

1. To completely disconnect the barrel, you need to gradually unscrew two screws.
2. After pressing the forend-fixing plate, the box with tubular under-barrel magazines is easily disconnected, and the bolt pusher is removed.
3. All KSG components are now accessible for inspection and cleaning. If necessary, you can also disconnect the forend using a hexagon.

Assembly is carried out exactly the opposite. It is worth paying attention to only three details: 1) the forend locking plate; 2) before tightening the screws, if they spin freely, it is necessary to slightly press the barrel into the box; 3) the shutter is put in place by twisting it 90 degrees. The assembly is verified by monitoring the proper operation of the feeder tray. After assembly, you should fire a blank shot so as not to leave the gun in an erected state.

Advantages and disadvantages

Advantages:

• Compact shotgun size due to bullpup design.
• Multi-charge.
• The KSG was created taking into account the combat requirements and tasks of the 21st century.
• Ability to load magazines with different types of ammunition. For example, buckshot and bullets. This will allow you to perform various combat missions.
• Convenient for working in a group, discharging spent cartridges under the feet and forward, and not to the side.
• The ability to use the magazine that is most comfortable (depending on your hand) for charging, while keeping a second magazine as a backup for an emergency.
• Good weapon balancing, both with a full magazine and with different amounts of ammunition.
• The shotgun can be used by both right-handed and left-handed people.
• The KSG is comfortable to shoot, and the movement after the first shot is comparable to any other gun.

Flaws:

• The legislation of a number of countries requires changes in the design of the shotgun for its legal use in the country. For example, attaching a DTK (muzzle brake compensator).
• Lack of built-in sighting devices.
• The sight must be high. This feature makes it inconvenient to use some collimator sights. The KSG is ideal for scopes used in conjunction with an AR-15 rifle.
• Some people may find the magazine selector to be a little short. But you can purchase an extended version from Kel-Tec.
• The KSG lacks the traditional shotgun side ejection window through which a cartridge can be inserted.
• Full mastery of the shotgun requires a lot of time and thousands of practice shots.

Kel-Tec Sub-2000

Now let's go back a little. Almost all the features that turned me off to this rifle make it special. Firstly, the weapon is very compact. The barrel length is only 41 centimeters, just enough so that the weapon does not have to be registered (in the USA - approx. lane). When unfolded, the length of the rifle is 75 centimeters.

The stock is a simple tube that allows the bolt to move. This means that if you are as big as I am, the weapon will seem small to you.

Magazines (Glock family) fit into the grip, just like a pistol. The magazine reset button is made very convenient. The fuse is also simple and convenient. The mechanics of handling weapons are simple and straightforward.

The base model's handguard is made of polymer. There is also the option of installing an aluminum quad rail forend, and I think that should be done first. In stock configuration, the rifle has enough length for good grip. It is also worth noting that the Sub-2000 has very little recoil thanks to the 9x19mm caliber.

The most important feature of the rifle is that it folds. It is very easy to fold and unfold. Moreover, if you fold the rifle when there is a cartridge in the chamber, then since the bolt will be in one part and the barrel in the other, the cartridge will simply fall out of the weapon.

Modifications

The KSG was created for civilian use, so modifications were not initially planned. However, the rapid growth in popularity of the shotgun in law enforcement agencies forced Kel-Tec to reconsider its position and release additional variations of the gun:

KSG 25 with a barrel length of 774.7 mm and a total length of 965.2 mm, and magazines of 10 rounds. Weight 4.2 kg. Price 1400$

KSG Tactical with a barrel length of 343 mm and a total length of 546 mm, and magazines of 4 rounds. Weight 2.8kg. Price 1200$
