6. BACKGROUND
It was russians who 1st recognised that most
of the wars were fought with short range.
Thus they though of designing a gun with
short range upto 300 m and which was brutal
assault rifle with more damage. To reduce the
cost cartidge size was shortened to that used
in long range fights.
A TYPE OF AK-47 RIFLE
7. Features Of AK-47
The main advantages of the Kalashnikov rifle are its simple
design, fairly compact size and adaptation to mass
production. It is inexpensive to manufacture, and easy to
clean and maintain; its reliability are legendary . The AK-47
was initially designed for ease of operation and repair by
glove-wearing Soviet soldiers in Arctic conditions.
8. OPERATING CYCLE
To fire, the operator inserts a loaded magazine, moves the
selector lever to the lowest position, pulls back and
releases the charging handle, aims, and then pulls the
trigger. In this setting, the firearm fires only once (semi-
automatic), requiring the trigger to be released and
depressed again for the next shot. With the selector in the
middle position (full-automatic), the rifle continues to fire,
automatically cycling fresh rounds into the chamber, until
the magazine is exhausted or pressure is released from the
trigger. As each bullet travels through the barrel, a portion
of the gases expanding behind it is diverted into the gas
tube above the barrel, where it impacts the gas piston. The
piston, in turn, is driven backward, pushing the bolt carrier,
which causes the bolt to move backwards, ejecting the
spent round, and chambering a new round when the recoil
spring pushes it back.
9. Disassembly
Dismantling the rifle involves the operator
depressing the magazine catch and removing the
magazine. The charging handle is pulled to the
rear and the operator inspects the chamber to
verify the weapon is unloaded. The operator
presses forward on the retainer button at the
rear of the receiver cover while simultaneously
lifting up on the rear of the cover to remove it.
The operator then pushes the spring assembly
forward and lifts it from its raceway, withdrawing
it out of the bolt carrier and to the rear.
10. Ballistics
