    In the early 1970s by the Soviet Army adopted a new perspective 5.45h39 mm cartridge. Using the new ammunition maloimpulsnogo promised a number of significant advantages, chief among which were a marked decrease in dispersion when firing, increased point-blank range, weight of weapons and ammunition wearable.

    Calculations showed that, along with increased performance characteristics (TTX) full-size army-type, allow the creation of a new cartridge compact small-sized automatic weapons, which experienced an acute need for military support and technical units, the number of which has increased steadily in the army. The possibility of creating such a model has been proved in the late 1960s, experts TsNIITochmash, where research and testing was a prototype lightweight compact machine AO-46 chambered for 5.45 × 39 mm.

    According to the results of research and testing machine AO-46 decision of the commission of the Presidium of the Council of Ministers of the USSR in 1973 was opened developmental work to create compact 5.45mm machine codenamed "Modern". In accordance with the tactical and technical requirements (TTM) new compact machine designed for weapons grenade, artillery, armored vehicles crews and other military personnel categories for which you want a compact weapon with high firepower, should provide the capability of automatic and single fire, have a mass no more than 2.2 kg, length buttstock with less than 750 mm with folded butt - not more than 450 mm Sighting range up to 500 m

    work to establish a compact machine embarked on a competitive basis arms designer Mikhail Kalashnikov, SG Simonov, SI Koshkarov, A. Konstantinov, I. Ya Stechkin.

    most original model of a new machine for the competition "Modern" presented designer Tula TsKIB COO Igor Yakovlevich Stechkin, created before this became known APS automatic pistol. Stechkin machine was assigned the designation TKB-0116 (Tula Design Bureau, sample number 0116).

    5,45-mm compact machine TKB-0116 has automatic return to the trunk when his short course. At the end of the barrel recoil transfers energy gate, accelerating its movement. Shutter is rigidly connected to the bolt. The barrel is locked by turning the stem in the fully forward position with the lugs on the barrel are engaged with the notches of the bolt carrier.

    Reflection sleeve made up through a closed ejection port cover that opens automatically when you move the bolt.

    nadulnoe Removable device simultaneously performs the function returns the trunk amplifier, brake compensator, flame arrester and reduces the sound level when shooting. This assembly allowed the use of various types of nozzles: silencing device for firing blank, etc.

    hammer-type firing mechanism allows single and automatic fire.

    To supply arms ammunition produced direct shop, housed 20 rounds and did not extend beyond the weapons, though it is possible to apply and staff shops from AK-74 capacity of 30 rounds.

    mechanical changeover sight has settings for shooting at a range of 100, 400, 500 m and "P" (permanent).

    folding metal stock leans up turning back until it stops.

    machine housed in the handle supplies for maintenance of weapons.

    decision section NTS Minoboronprom Izhevsk revised sample was sent to the military tests in the future under the symbol AKS-74U (6P26) was adopted by the Soviet Army, and then the Ministry of Internal Affairs of the USSR. The decisive argument in its favor was the high degree of commonality with those already adopted for service AK-74.

    Although

    Stechkin automatic TKB-0116 a number of indicators surpassed other products submitted for the contest is "Modern" was simple, technologically, is original and has passed more tests in 1977, it still remained within the prototype, and hold it further refinement was decided impractical.
