The Zastava M77 is a 7.62x51mm battle rifle and light machine gun developed and manufactured by Zastava Arms. [2] It is a Kalashnikov pattern rifle based on the Zastava M70 . While early versions of the M77 had a milled receiver, later variants would be built with the standard Yugoslavian 1.5mm stamped RPK receivers.
The Zastava M77 B1 is a battle rifle developed and manufactured by Zastava Arms in Serbia (formerly Yugoslavia). [3] It was introduced in 1977. [4] It is a derivative of the Zastava M70 [4] and modified copy of the Soviet AKM [1] chambered in 7.62×51mm with an enlarged receiver, [4] and a Western-style flash suppressor. It is gas-operated, air ...
Yugo (pronounced) is the common name used for the Zastava Yugo, [1] later also marketed as the Zastava Koral (pronounced [ˈzâːstaʋa ˈkǒraːl], Serbian Cyrillic: Застава Корал) and Yugo Koral. Originally introduced as the Zastava Jugo 45, various other names were also used over the car's long production run, like Yugo Tempo ...
English: Block diagram of a tuned radio frequency (TRF) receiver, the simplest type of amplifying radio receiver circuit. It consists of one or more tuned RF amplifiers, each consisting of a tuned circuit which functioned as a bandpass filter followed by a radio frequency (RF) amplifier; a detector (demodulator) to extract the audio waveform from the radio carrier wave; followed by an audio ...
English: Block diagram of a crystal radio, the simplest type of radio receiver which was invented in the early 1900s and widely used until vacuum tube receivers replaced it.
Attaching the barrel to the receiver using a barrel nut and a barrel with a shoulder is an alternative to action threads, which has been used in firearms such as the Sten gun and AR-15. Hand tools Quick barrel change systems is an increasingly popular alternative, as seen in for example SIG Sauer 200 STR , Roessler Titan or Blaser R8 .
[citation needed] In 1994, Serbia developed a new version called the M-94 Oganj C, which could fire the rockets M91 (cluster-type warhead with 40 submunition grenades) and M77 (HE warhead). This version featured a 32-rocket reloading system which makes it possible to fully reload and launch a second salvo within three minutes.
In order to achieve both good adjacent channel selectivity and image rejection, the double-conversion receiver uses two intermediate frequencies (IFs). The incoming radio frequency (RF) signal from the antenna is first mixed with a sinusoidal signal from the 1st local oscillator (LO) to give a high 1st IF frequency.
