Caliber:7.62¡Á39mm

CzechSA Vz.58Department of assault rifles because of its
shape and the famous KalashnikovAK-47Assault rifles similar
to known, although their structural principle is not the same.
SaidCzech deliberatelyVz58Designed this form, it wants to
borrowAKOf fame to get better sales, but inWarsaw Pact countries,Vz58Assault
rifle is relatively rare "original" one of the assault
rifles, because at that time the vast majority of the Warsaw
Pact countries are a direct imitation of Soviet-style using
their ownAKRifle.
Vz58Full nameSamopal vzor 1958, From the literal translation
is "1958Assault rifle "means, of course, we all
know is actually a rifle assault rifles. More accurate abbreviation
should be"SA Vz.58"ButIs often referred to asSa58OrVz58,
But because it is the production of weapons in the Czech Republic,
it will be sometimes incorrectly referred to as theCZ58.
Vz58AssaultRifle small arms designer from the Czech Republic
Jiri Sai Make (Ji?¨ª ?erm¨¢k) In the1956Year1Began research
and development, the new gun design projects have been named
"KO?T¨§", Translated into Chinese, that is,"
broom "in Italian. The new gun in two years after1958Years,
was finalized and adopted soon located in the Czech Republic
Urs brod state arsenal (Uhersky Brod ?esk¨¢ zbrojovka) Into
production. In fact, as early as1953Years, the other a Czech
arms designer Emmanuel Talha Lectra (Emanuel Holek) In relation
to designOf a Kalashnikov rifle, the Czech government has
also carried out experiments on the rifle,Kazakhstan is the
Sai Make Lectra's design-based improvements to designVz58Assault
rifles, perhaps this is theVz58Assault rifles shape andAKAssault
rifles similar to the real reason for bar.Emmanuel Talha LectraIn1920Designed
in the lateZH-29Automatic rifles, the semi-automatic firing
mode, or choose automatic rifle at that age is very trendy
concept, the then Chinese government has also purchased a
small group to try, and now in Beijing, the Chinese People's
Revolution Military Museum of the light weapons on the Showcase
hanging from aZH-29Automatic rifles.
Vz58Since the assault rifle series1958Age became Czechoslovakia's
army standard rifle, a comprehensiveTo replace the original
equipmentM23,M24,M25,M26Submachine gun and the52Type and52/57-Style
semi-automatic rifle, which not only equipped with the Czech
RepublicAndSlovakiaThe Federal Republic ofSea, land and air
forces, but also to equip border guards and militia.
When the Czech and Slovak Federal Republic1993Was re-separated
into two independent countries, the Czech Republic in order
to move closer to NATO, has developed, including assault rifles,
short assault rifles and light machine guns, including three
kinds of modelsCZ-2000Gun family (formerly known as theLADASeries),
and intended to use this emission5.56mmThe new NATO-standard
bullet to replace the gun familyVz58Series, however, due to
financial difficulties, delay in the implementation of procurement
plans, resulting inVz58Series in the Czech Republic serving
in the armed forces for nearly half a century, and evidently
will continue in service go. The Slovak army because there
is no suitable alternative products and the continued use
of this type of weapon.
In addition to military use in the Czech Republic and Slovakia,
theVz58Assault rifles have been exported to other countries
in the world, there are90A number of countries or regions
use of such armed assault rifle. ButAKRifle thanVz58The number
in the world is still too small, so few show up on the battlefield.
Vz58Assault rifle series launched the Warsaw Pact7.62 ¡Á 39mmIntermediate
power rifle rounds,The series developed to mainly the following
models:
SA Vz.58P
A fixed standard infantry rifle, the main equipment of conventional
forces, the butt of the early wood, late into plastic.
SA Vz.58V
Folding metal butt type, major equipment, armored units, airborne
troops and special forces.
SA Vz.58Pi
Night-type, in theSA Vz.58PRifle casing with a dovetail slot
on the left to install a long scope mount for the installation
of infrared night vision sight, with two tripods, is installed
on the cone-shaped muzzle flash suppressor and efficient to
avoid when shooting at night The muzzle flame interfere with
night vision sight.
SA Vz.70
5.45¡Á39mmCaliber experimental, this is the1976To1978Developed
in the years that the name has not been proven stereotypes.
CZ 858 Mk.IITactical
Semi-automatic civilian type, with folding stock, barrel length
of390mmAnd482mmTwo kinds.
AsCZ-2000Gun family, costume changing plans within the foreseeable
future, at present the Czech Republic only to active duty military,
theVz58Assault rifles modernizing, for example, four weeks in
nursing plus Pikatingni wood rails, and purchased a new type
of aiming device, in theVz58VSteel butt paste on the gills with
plastic panels.
AndAK-Type assault rifle the same asVz58Assault rifle is
also a derivative gas-operated automatic weapons, but the
latter uses a short stroke piston design, latch-way latch
card iron swing (also known as the ups and downs of wedge-type),
firing mechanism belongs to hammer translation type; TheAKSeries,
compared with a long stroke piston, rotary and rotary hammer
lock. Therefore, although the appearance of similar, but different
internal structure.
Vz58Assault rifle barrel is located above the guide gas installations,
gas piston guide has a separate recoil spring, recoil stroke
is about19mm. There are two air chamber beneath the vent,
piston recoil16mmWill leave after the indoor air, gas and
powder room gas will escape from the exhaust vent. The piston
and the barrel axis center distance between the small, only
the19mm, Can reduce the gunpowder gas acting on the impulse
from the piston, to improve the shooting accuracy benefit.
Rifle with iron swing-type locking system, similar to the
German Walter CardsP38Semi-automatic pistol lock body. Bolt-ons
from the bolt, latch-card iron, firing pin, pull the shell
hook, pull the shell hook springs and top pins formed in the
bolt latch-card iron hinged bottom bolt front-end addition
to bombs, at the end of nest, pushing convex shells bamboo
shoots, pull the shell hook nest and two symmetrical latching
convex bamboo, the bamboo on the right side convex short positions
in front of a hanging slot, the following grooves to throw
shells by Ting. In addition, both sides of a symmetrical rotary
shaft hole to install the rotor back iron latch card ear.
On both sides of the guide rail bolt guide slot in the machine
frame movement. Pinhole stretching from the rear is a hammer
blow hole, easy to hammer against firing pin. Wire drawing
machine handle installed on the machine frame on the right.
Closed-bore gun is to be hit. When the shooting fat, the guided
gas piston recoil and impact machine frame, machine frame carrying
about22mmFreedom of travel, the latch card iron machine frame
under the action of unlocking slope upward from the receiver
on the swing and the latch groove, thereby bolt lock, while
preparing to play the role of smoke shells. Then the gun crew
as a whole began to backward movement, Chouchu Kong cartridge,
and then thrown thrown under the action of the shell pretty
shell. When the gun crew during re-entry into the bore it delves
into a new bomb. When the bolt recoil in place, machine frame
locking down the slope forced the latch card iron swing, latch
lock slot protruding shoots into the receiver, after machine
frame to continue to re-enter, has completed post-lockout free
trip, allow the plane of plane frame blocking the latch card
iron limitation surface, blocking the completion of action indeed.
As the gun crew of the two movements guide a larger spacing,
it increases the driven machine frame bolt torque, so that
the energy consumption increase Machine frame and affect the
reliability of body movement. Machine frame bolt driven through
the latch-card iron middleware to achieve, and in tight re-entering
wedge generated when the phenomenon of increased frictional
resistance also affects the reliability of body movement,
in addition to pushing up the bomb during the hold when the
bullet shells from the mouth After easily stuck in the bolt
of the lower side rail, an increase of push bullet resistance,
which in turn is an agency action affecting the reliability
of reason. China in1980BC had a number of foreign light weapons,
carried out extensive comparative test, in the rightVz58Assault
rifles water immersion test, every hair in place have emerged
re-enter without fault.
Receiver cover, recoil spring devices and hammer:1- Casing
cover;2- Recoil spring;3- Hammer spring
In the rifle is designed to have a logistical nature of the
defects, if lacking the iron lock card can not latch, but
theVz58Assault rifle was able to iron in the absence of latch-card
combination of circumstances and launch, and when the gun
does not lock in the case of shooting a serious accident occurs,
so soldiers in the decomposition of the maintenance re-combination
of rifle must be very careful.
Vz58The firing mechanism for the hammer Horizontal (or called
the hammer direct-acting type), this design is also different
from the common hammer rotary design. Hammer is a hollow steel
tube, inner spring inside the hammer and hammer spring guide
rod, guide rod fixed on the casing cover, and parallel with
the recoil spring. Hammer connected with the machine frame,
machine frame when the rear with the rear driving hammer,
machine frame re-enter after the hammer was hanging in the
rear of the firing to be relieved when the drop hammer sear
in the hammer under the action of spring force hammer separate
forward movement along the guide casing, impact firing pin.
Large size cylindrical firing pin does not spring from the
pull-hook the rear convex shell limit shoots behind the bolt
so that it can not hit inside the pinhole in the prolapse.
Hammer-type firing mechanism shifting the advantage of firing
produced by beating a small, helping improve the rifle-shooting
accuracy, there is a kind of argument is95-Type assault rifle
firing mechanism that is affected by the uniqueVz58Inspired
self-developed, although the structure is different, but the
principle is similar.
The overall design of the plate unit is relatively simple,
but very few moving parts. By (percussion) resistance iron,
single shot, firing rod (bursts of resistance iron), triggers,
speed machine, composition and position of leaf spring leaf
spring formed, and through the trigger shaft, blocking iron
shaft and connected to the crankshaft speed receiver on the
leaf spring limited by the location could not get out of the
various axes. Single truss rod and firing placed side by side,
but the single bar front1.6mm, Firing rod is in place the
insurance and non-iron-linked resistance, and only in the
machine frame lock is finalized, the insurance sear in order
to jack up shots bursts.
Insurance Manual/Speed machine handle in the right side of casing,
there is3Install a given position, namely, insurance, single
and fully automatic. Installed in the insurance position, speed
of machine shaft at the same time depressed single shot and
firing shots, so that they iron out with the resistance, this
time while still be able to withhold the trigger, but can not
escape hammer sear.
Manual Insurance Status
The pace set by the automatic machine handle position, speed
of machine shaft alignment gap firing rod, the latter under
the action of spring force swarmed with blocking iron fastening,
single rod was depressed, and sear off. Withhold the trigger,
firing sear rod driven down relief hammer, hammer re-advance
on hair. After firing, machine frame driven hammer, with the
rear bolt. Not in place the insurance drive rod sear relief,
combined sear leaf spring so that the insurance recovery in
situ. Hammer into the rear seat in place after re-start, but
only re-enter a very short distance, followed by insurance,
sear withholding. If the withholding trigger link, and then
re-entered when the machine frame in place depressed are not
in place when the drive rod sear insurance, insurance, namely,
relief hammer sear, hammer and then re-direct re-firing.

Set the speed semi-automatic machine handle mounted position,
speed of machine shaft alignment gap in single pole, single
pole lift hang sear; firing rod was depressed, and with resistance
from the iron. After firing, the rear frame in the machine process,
the machine frame under the bump on the left depressed single
pole, so that separation with the sear, sear the role of the
combined leaf spring to resume in-situ. When the machine frame
recoil relief in place is not in place insurance, sear, the
hammer will be forward movement, but only moving1.6mmJibei resistance
iron withholding. To re-launch, you must first release the trigger,
so that single shot back at the top of lift, re-hang sear, this
time to re-trigger before firing withheld.

Sight is an open, aimed at long-baseline356mm. Sight for
the column, there are guard; sight for theVNotch type, rear
sight sub-classified as a100~800mEach sub-classified as a100m,
No wind bias correction. Zero calibration may rotate or move
horizontally up and down to sight.
Sight on the barrel/Bayonet base, under the care of Gas hoop
and wooden hoop, are fixed with the pin. Guide holes in the
barrel before the top of the surface away from the barrel
end of the216Mm. Muzzle with a muzzle cap connected by a threaded
muzzle with cone angle.
Vz58The casing, machine frame, etc. are machining parts,
iron and other cards in the latch-key components of the chrome-plated,
wear-resistant and easy cleaning. Butt, grip and protect wood
from wood cellulose filler material made of plastic, so the
gun lighter. Rifle with a magazine with the board have short
positions to shore up shells hanging sudden shoots, it can
not beAKRifle cartridges interchangeably.
Vz58Assault rifle has the advantage of light weight, good
accuracy drawback is that reliability is poor, harsh environment
high failure rate, in addition, individual components of combination
is not good when the logistical support.
Vz58Assault rifle decomposition process is as follows:
1) Unloaded magazine, pull back the machine handle to check
whether there is actually no bullets inside the chamber. If
the hammer in the rear, should withhold the trigger to hammer
recoil to the front of the position;
2) Pulled the right rear of the receiver cover pin connections,
will push the casing cover slightly forward and lift the back
end, remove the receiver cover, recoil spring, hammer spring
be removed;
3) Back drawing machine handle, break out the machine frame,
bolt, latch card iron and hammer, etc.;
4) Pull hammer back until the sudden gap in alignment machine
frame on the left edge convex bamboo shoots, it will hammer
counter-clockwise rotation1/8Turn, back out;
5) Pulled right in front of the rear sight base connection
pin, lift the end of protecting wood, remove the retaining
wood;
6) Pull the piston back, when the piston head out of gas
chamber, the slightly swarmed, remove the piston and piston
spring.
