TKB - Tula Design Bureau (Тульское конструкторское бюро - Tul'skoye konstruktorskoye byuro)
- TKB-09 - 5.45x39 - The TKB-09 is one of the prototype rifles by German A. Korobov that uses a cable/cam counter recoil system.
- TKB-010 - 7.62x39 - The TKB-010 is one of the prototype rifles by German A. Korobov that uses a cable/cam counter recoil system.
- TKB-011 - 7.62x39 - The TKB-011 is a bullpup rifle designed by Nikolai M. Afanasyev between 1963-1965. The rifle is made from steel with an external chassis made of bakelite. The TKB-011 and TKB-022PM were the first rifles to use a tunnel ejection port now famously seen on the FS2000.
- TKB-015 - 7.62x54R -
- TKB-022 - 7.62x39 - The TKB-022 is one of the most unique firearms in the gun world today. It was designed in the early 1960s by German A. Korobov with the TKB-022 being released in 1962. They were gas operated with an annular gas pistol located around the barrel with a vertically moving bolt which made it possible for the receiver to be as short as possible. A U-Shaped extractor was used to chamber and extract rounds from the magazine by pushing it into the chamber after extracting a spent round from the chamber, while feeding in a new round, the spent case is then pushed into a tube above the barrel where it exits above the muzzle. Because of the ejection setup, it is ambidextrous. Because of the operation system of the weapon it is extremely compact with an over all length of 525mm (20.7in) and a barrel length of 415mm (16.3in). It is claimed the rifle had better accuracy then the AKM when lying from the prone position of a distance of 100 meters. Despite the innovations of the platform, the rifle was ultimately rejected by the Soviets because of the concerns with the rearward center of gravity, the weapons durability due to the polymer housing, and the radical design.
TKB-034 - The TKB-034, better known as the RPG-16 is rocket launcher designed in 1968 by Bazalt. It went into production in 1970. The RPG-16 fires teh PG-16V rocket with its 58.3mm warhead. It like the RPG-7, fires a shaped charged explosive. It is capable of penetrating armor up to 300mm (11.8 inches). It has a range of 500-800 meters (1640-2625 feet) and a velocity of 350 meters per second (1148 feet per second).
- TKB-047 - 43x140mm - The TKB-047 (OKV-40) is a fragmentation grenade designed by K.V. Demidov to be used with the TKB-048 Iskra (OKG-40) grenade launcher. The design requirements was to great a weapons with at least 40mm that could fire between 50 and 400 meters. An explosive charge placed in the body of the grenade with a shape charge in the cone. This allowed the grenade to penetrate armor. A sleeve was attached to the rear of the body which contained the primer and charge to send the grenade down range.
- TKB-048 - 43x140mm - The TKB-048 Iskra (OKG-40) was an experimental underbarrel grenade launcher. It was designed in 1963 but Viktor V. Rebrikov. The original idea for a rifle mounted grenade was to use one that slipped over the muzzle and the firing a blank to send the grenade down range. This idea had been used all the way up to WWII. After testing it was determined they were not getting the distances and power from the grenade they were hoping for so they later decided to try a self contained round. What they came up with was a low pressure underbarrel launcher. Ironically enough countries such as Poland and Yugoslavia, to name a few, would go back to the muzzle fired grenade launchers. As of 1966 the US Military and the Soviet Red Army were both working on underbarrel grenade launchers, both unaware of each others progress. Because the TKB-048 featured a pistol grip, it resembled more of a flare gun, then what we would think of as a grenade launcher today. To attach the launcher to the rifle it would lock onto the bayonet lug and slip around the muzzle, in a similar fashion as a bayonet would. It had its own trigger as well. On the left side of the unit, it featured folding sights as the standard rifle sights would not work. It was designed to be shot like a mortar, which means butt on the ground. It is reported the grenades the TKB-048 uses could punch through 50mm of armor during trials, but the unit performed poorly and development was halted by 1970. It is considered Russia's first grenade launcher and one of the first underbarrel grenade launchers.
- TKB-049 Fakel
- TKB-059 - 7.62x39 - The TKB-059 is a three barrel bullpup rifle designed by German A. Korobov between 1962-1966. It is based on the Pribor 3B, which is an earlier experimental rifle with three barrels also designed by German. Both the TKB-059 and the Pribor 3B are fed from a 90 round magazine with each barrel independently fed from the same magazine. The TKB-059 ejects from the bottom of the rifle, in front of the magwell resulting in the rifle being ambidextrous. The rifle can be seen at the Tula Arms Museum.
- TKB-072 - 5.45x39 - The TKB-072 was a rifle designed by German A. Korobov in 1975 and manufactured by TsNIITochMash. The rifle was submitted to trials in the late 1970s in which it met all the requirements, however in the later parts of the competition the Ministry of Defense Industry requested a simplified version of the rifle to be made, and as such Korobov created the TKB-072-1. Unfortunately for Korobov the weapon was removed from trials program all together as the fire selector was needlessly complicated and was seen as not real advantage over current rifles. The TKB-072 uses a recoil system similar to what would be later called the BARS. It allowed the rifle to have a 2 round burst of 2000 RPM, while normal full auto fire was round 500 RPM. The extreme rate of fire for the 2 round burst allowed it to get off two rounds before the shooter felt the recoil of the first one, and the slow rate of fire under full auto allowed the shooter to easily control the rifle.
- TKB-0111 - 5.45x39 - The TKB-0111 is a prototype rifle designed by German Korobov and manufactured by TskIB SOO. The rifle took place in the Project Abakan trials as one of the original eight rifles. The rifle was eliminated very early in the trails as it was not deemed promising as a weapon platform. It features a rather larger muzzle device as well as a high rate of fire with its burst mode. Standard rate of fire was 500 rounds per minute, and in burst it was 1700.
- TKB-0116 - 5.45x39 - The TKB-0116 is a prototype rifle designed by Igor Stechkin and was manufactured by TsKIB SOO. It was part of the trails program which ultimately gave us the AKS-74U. The TKB-0116 is a short recoil operated rifle. It features a top folding stock (thought a solid woodend stock was also an option), a muzzle device that acts like a booster to help system the weapon and to kill the flash of the rifle as it is fired. It also had a proprietary 20 round magazine, but a standard AK-74 mag would also work in the firearm. While the TKB-0116 did better then some of the other weapons in the trails, it ultimately did not have the same reliability as the Kalashnikov design, now known as the AKS-74U. The TKB-0116 never went past the prototype stages of development.
- TKB-0125 - 72.5mm - The TKB-0125, better known as the RPG-22 Netto, is a single shot disposable rocket launcher designed in the early 1980s and went into production in 1985 by Bazalt. It was designed to replace the RPG-18, which it did completely by 1990. The design of the rocket is very similar to that of the US Military M72 LAW. The tube is made of two parts, both being constructed of fiberglass. It consists of the main tube and the telescoping forward extension which slides over the weapons barrel. There are end caps that cover both ends of the tube when transporting or storing the launcher. The TKB-0125 is cocked by lifting the rear sight, and can be decocked by lowering the sight. The backblast area is 15 meters (50 ft).
- The TKB-0125 fires the PG-22 round, which is a 72.5mm shaped charge HEAT (High Explosive Anti Tank) warhead which can penetrate 400mm (15.7 in) of rolled homogeneous armor, 1000mm (39.4 in) of reinforced concrete, and 1200mm (47.2 in) of brick. The rocket uses all its propellant completely while still in the tube where it accelerates it to 133 m/s (436 fps).
- TKB-01455S - 6x49 - The TKB-0145 is an experimental bullpup rifle featuring a somewhat unusual folding receiver. There were several versions of the rifle designed in the TKB-0145 series, but the 'S' variant is the final design. To give some backstory of how the rifle came to be, the 6x49mm round (known as 6mm Unified) was supposed to replaced the 7.62x54mmR cartridge in machine guns and sniper rifles, so a trails program was put into place to to design a series of new machine guns and rifles which would fire the new round. This would lead us to the TKB-0145, which was designed by Alexander Adov. One of the main requirements for the new rifle was to make the weapons as compact as possible so issue with vehicle troops and paratroopers. So to get the length down Adov started with a bullpup design to make the over all length as short as possible. The rifle features a 28.3 inch barrel, so that helped. His second step was to make the rifle fold in half to make storage better. In its folding configuration the over all length was only 32.8 inches. The hinge point of the rifle is in the receiver, in front of the rear sight block. The rear of the rifle has a spring loaded latch to lock the rifle in place when folded.
- The gas system was rather unusual as well. It does not have a gas port in the barrel like most traditional rifles do, yet it as a system very similar to the Bang rifle. The design was said to eliminate any possible effects the gas system would have on the bullets flight.
- TKB-0146 - 5.45x39 - The TKB-0146 is a bullpup rifle designed by Igor Yakovlevich Stechkin. The rifle participated in Project Abakan. Nikonov and Stechkins designs were the only innovating designs in the Abakan trials that made it to the final rounds of testing. The other 6 rifles in the competition were based on more conventional rifle designs. The TKB-0146 could fire two round burst at 2000 RPM or sustained full auto fire at 600 RPM. During the trials it was determined the TKB-0146 was slightly more accurate then Nikonov design, but less reliable. Nikonov design won the competition and became the AN-94. To switch from semi auto to full auto there is a switch behind the trigger. Pulling the trigger back slightly fired a single round, while pulling the trigger all the way back would hit the switch behind the trigger causing it to fire in full auto. A similar design would later be found on the Steyr AUG. To switch to two round burst a done by flipping a lever, which would convert the rifle to full auto to burst buy doing the same trigger squeeze as full auto. Two examples can be found in the Tula Arms Museum, one of which is an early prototype with 3 round burst rather then two.
- TKB-0175 - 105mm - The TKB-0175, better known as the RPG-29, is a rocket launcher designed in the 1980s and went into production in 1989 by Bazalt. The RPG-29 is a shoulder fired and unguided anti tank rocket launcher that has a range of 500m. It is designed to carried and operated by a single soldier. It uses the 1P38 sight which has a 2.7x magnification. A 1PN51-2 night vision optic can also be fitted. The PG-29 rocket the RPG-29 fires has 8 fins which are deployed automatically when the rocket exits the tube when fired. There is a shoulder brace on the bottom of the tube to help the shooter stabilize the launcher when firing and a forward pistol grip.
- The RPG-29 has two different rockets it can fire. The PG-29V tandem warhead and the TBG-29V thermobaric warhead. Both are 105mm shaped warheads. The PG-29V has a stated penetration capability of 750mm (29.5 in) of rolled homogeneous armor, 600 mm (23.6 in) of rolled homogeneous armor after explosive reactive armor effects, 1500 mm (59.1 in) of brick or reinforced concrete, or 3700 mm (145.7 inches) of reinforced log and earth fortifications.
- TKB-0249 - 30x29mm - The TKB-0249 is a magazine fed 30mm grenade launcher. It was designed in the later 1980s by Valery Nikolayevich Telesh. It went into production in the later 1990s by TsKIB SOO. The TKB-0249 has an extra long receiver to hold a compensator system to reduce felt recoil on the shooter. It reduces the recoil to that of a light machine gun. It feeds from either a 5 round box mag or a 10 round drum. It features a built in bipod to aid in shooting from a fixed position. It can be used with a PSO-1 optic which allows the weapon to fire out to 1700 meters. The TKB-0249 uses the same 30x29mm grenades used in the AGS-17.
- TKB-408 - 7.62x39 - The TKB-408 is a bullpup rifle with a tilting bolt designed by German A. Korobov and was submitted to trails in 1946 to the Red Army as their next main rifle. Of the trails, none were selected although the AK-47 was later adopted after several revisions, some being major changes. The TKB-408 is a select fire wit semi and full auto fire capabilites. The fire selector is located on the left side of the pistol grip.
- TKB-486 - 9x18mm - The TKB-486 is a blowback submachine gun designed by Igor Stechkin in 1955 and manufactured by TsKIB SOO. It was the first submachine gun to use the 9x18 round. It has a cyclic rate of 550 RPM. It has a folding magazine, and combined with its folding stock it becomes very compact for storage.
- TKB-506 - 7.62x35 SP-2 - The TKB-506 is a conseable gun designed by Igor Stechkin in 1954. it was designed to be used by KGB operatives and fires the silent 7.62x35 SP-2 round. It is designed to look like a cigar tin. It features three barrels with a trigger is designed to look like the button that opens the case.
- TKB-506B - 7.62x35 SP-2 - The TKB-506B is an updated version of the standard concealable pistol. It features a more traditional pistol layout.
- TKB-517 - 7.62x39 - The TKB-517 was designed by German A. Korobov in 1957 and never left the prototype stage. In 1957 the Soviet Main Missile and Artillery Directorate (GRAU) issued a set of requirements for a new rifle for the Soviet Army. The rifle was to fill the role of a LMG and an assault rifle and was to be more accurate then the AK-47 which was a newly adopted rifle. They wanted the rifle to be cheaper to manufacture as well. The rifle was submitted for trails from Jan-Feb of 1957. The main competitor to the rifle was the updated AK-47, the AKM. During the beginnings of the trails the TKB-517 was universally liked over the AKM, as it was said to be more accurate. As a result a rate reducer was added to the AKM, which was also found on the TKB-517. As the trails ended in 1958 only the TKB-517 and AKM were the only two rifles that were deemed suitable for adoption with the GRAU requesting that both weapons be updated. The Kalashnikov design was refined by the engineers at Izhmash, with modifications to the TKB-517 being delayed. In the end the TKB-517 was rejected for the AKM as the delayed blowback design did not seem to give any advantages to the more traditional gas operated Kalashnikov design. The revised AK was dopted in 1959 as the AKM.
- TKB-579 - 7.62x54r - The TKB-579 is a sniper rifle designed by German A. Korobov in 1958 and manufactured by TsKIB SOO. Its intended goal was to enter in the trails to replace the Mosin-Nagant Sniper Variant. It is reported the rifle functioned so poorly that GRAU simply declined to test the weapon. The competition was ultimately won by the SVD sniper rifle designed by Yevgeny Dragunov.
- It is a gas operated rifle with a somewhat unusual gas system. It has a gas port on the top of the barrel like a conventail rifle, but also on either side of the barrel for a total of 3 gas ports. The rifle has the option to fire full auto if need be.
