Sinak zar nije aka 47-ca? I da ta tema je stara od kada su napravljene puce. 16-ca ima vecu preciznost i domet, dok je "Kalash" efektivan do nekih pola km, ali zato efekat-ogromna razorna moc zrna velikog kalibra.

These modifications were primarily the result of converting the rifle to the intermediate-caliber 5.45x39mm cartridge, in fact, some early models are reported to have been converted AKMs, with the barrel resleeved to 5.45x39mm.[1] The result is a more accurate rifle than the AKM.[2] The AK-74 and AKM share an approximate 50% parts commonality (interchangeable are most often pins, springs and screws).

The rifle’s operation during firing and reloading is identical to that of the AKM.[2] After ignition of the cartridge primer and propellant, rapidly expanding exhaust gases are diverted into the gas cylinder above the barrel through a vent near the muzzle. The build-up of gases inside the gas cylinder drives the long-stroke piston and bolt carrier rearward and a cam guide machined into the underside of the bolt carrier rotates the bolt approximately 35° and unlocks it from the barrel extension via a camming pin on the bolt. The moving assembly has about 5.5 mm (0.2 in) of free travel which creates a delay between the initial recoil impulse of the piston and the bolt unlocking sequence, allowing gas pressures to drop to a safe level before the seal between the chamber and the bolt is broken. Like previous Kalashnikov-pattern rifles, the AK-74 does not have a gas valve; excess gases are ventilated through a series of radial ports in the gas cylinder. The AK-74's bolt has a larger extractor claw than the AKM.[1] Other minor modifications were made to the bolt and carrier assembly.

The rifle received a new, reinforced barrel[2] with a chrome-lined bore and 4 right-hand grooves at a 200 mm (1:8 in) rifling twist rate. The front sight base and gas block were also redesigned. The gas block contains a gas channel that is installed at a 90° angle in relation to the bore axis. A pair of support brackets are cast into the gas block assembly and are used to attach a BG-15 or GP-25 under-slung 40 mm grenade launcher. The forward section of the front sight base features a threaded collar that is used to screw in a newly-designed multifunction muzzle device (performing the role of a muzzle brake, recoil compensator and flash suppressor) or a blank-firing adaptor. The muzzle device is held in place by a spring-loaded button and is quickly detachable. The distinctive muzzle brake features a large expansion chamber, two symmetrical vertical cuts at the forward end of the brake and three vent holes positioned to prevent muzzle climb and lateral shift to the right (for right-handed shooters). A flat plate near the end of the brake produces a forward thrust when emerging exhaust gases strike its surface, eliminating nearly all felt recoil. The muzzle brake prevents backblast from reaching the firer, although it is reported to be harsh on bystanders as the muzzle gases are dispersed to the sides.[3]

The AK-74 was equipped with a new stock, handguard (which retained the AKM-type finger swells) and gas cylinder. The stock has a different shoulder pad than the AKM, which is rubber and serrated for increased traction. In addition, there are weight-reducing lightening cuts on each side of the buttstock. These also function to distinguish externally by sight and touch between the AKM and the AK-74, preventing the accidental loading of the wrong ammunition in the AK-74. The stock, lower handguard and upper heatguard were first manufactured from laminated wood, this later changed to a synthetic plum and then a black-colored polymer.

The AK-74 gas tube has a spring washer attached to its rear end designed to retain the gas tube more securely. The lower handguard is fitted with a leaf spring that reduces play in the rifle's lateral axis by keeping the wood tensioned between the receiver and the handguard retainer. The receiver remains nearly identical to that of the AKM; it is a 1 mm (0.0 in) thick sheet steel pressing supported extensively by pins and rivets. The internal guide rails on which the bolt carrier travels are stamped and spot welded to the inside of the receiver housing.[1] Minor changes were made to the front barrel and rear stock trunnions as well as the magazine well. All external metal surfaces are coated with a glossy black enamel.

The original AK-74 magazine was identical to that of the AKM, except for minor dimensional changes required by the 5.45x39mm cartridge. These rust-colored magazines are often mistakenly identified as being made of Bakelite (a phenolic resin), where in reality, they were fabricated from a two-part glass-reinforced polyethylene plastic molding, assembled using an epoxy resin adhesive.[1] Noted for their durability, the magazines did however compromise the rifle's camouflage.[1] A new dark-brown 30-round magazine was introduced in the early 1980s, composed of ABS plastic. All AK-74 magazines have a raised horizontal rib on each side of the rear lug to prevent their use in a 7.62x39mm AK. The magazines can be quickly recharged from stripper clips. The 40-round plastic magazine of the RPK-74 light machine gun is also interchangeable with that of the AK-74.

Accessories supplied with the rifle include a 6H4-type bayonet, a quick-loading device, three spare magazines, four 15-round stripper clips, maintenance kit, cleaning rod and sling. The bayonet is installed by slipping the muzzle ring around the flash hider and latching the handle down on the bayonet lug under the front sight base. The rifle fires the intermediate 5.45x39mm M74 rifle ammunition that includes the jacketed, steel-core 7N6 bullet, 7T3 tracer round and a blank cartridge. The ammunition was developed by a team of designers led by Victor Sabelnikov.

One of the rifle’s main versions is the AKS-74 (S – So skladnym prikladom) equipped with a side-folding metal stock. This variant, designed primarily for use with air assault infantry was developed and introduced alongside the AK-74. Unlike the AKMS's somewhat fragile underfolding stock (modeled after the MP-40 submachine gun stock), the AKS-74 stock is fabricated from stamped sheet metal struts, machine pressed into a "U" shape and assembled by punch fit and welding. The stock has a triangular shape; it lacks the folding shoulder pad found on the AKMS stock and is folded to the left side of the receiver. The hinged stock is securely locked in place in its extended position by a spring-loaded buttton latch located at the rear of the receiver on the left side. When folded, the stock is held closed by a spring-loaded capture hook in the left forward end of the receiver. A rear-mounted sling swivel is also provided and placed on the right side at the beginning of the stock frame.

In 1979 a shortened variant of the AKS-74 was adopted into service – the AKS-74U (U – Ukorochenniy) carbine, which in terms of tactical deployment, bridges the gap between a submachine gun and assault rifle. It is intended for use mainly with special forces, airborne infantry, rear-echelon support units and armored vehicle crews. The rifle's compact dimensions, compared to the AKS-74, were achieved by using a short, 210 mm (8.3 in) barrel (this forced designers to simultaneously reduce the gas piston operating rod to an appropriate length). In order to effectively stabilize projectiles, the barrel’s twist rate was increased from 200 mm (1:8 in) to 160 mm (1:6.3 in). A new gas block was installed at the muzzle end of the barrel and a new conical flash hider was used, which features an internal expansion chamber that alleviates gas pressure generated during firing. The flash suppressor locks into the gas block with a latch placed on the right side. The forward sling loop was relocated to the left side. The front sight is integrated into the gas block.

The AKS-74U also has a different sight system arrangement with a U-shaped flip sight instead of the standard sliding notch sight. The rear sight has two settings: “P” (fixed for firing at 350 m) and “4-5” (used for firing at distances up to 400–500 m). The rear sight is housed in a semi-hooded shroud that is riveted to the receiver top cover. This top cover is connected with the gas tube cover and is hinged, pivoting forward when opened. Both the gas tube and handguard are also of a new type and are shorter than analogous parts in the AKS-74.

The AKS-74U is significantly more maneuverable in tight quarters than the AKS-74, however the steep decline in muzzle velocity from 900 m/s (2,952.8 ft/s) to 735 m/s (2,411.4 ft/s) resulted in a decrease in effective aimed range (the effective hitting distance for a “running”-type silhouette was reduced from 625 to 350 m).[2] The carbine cannot mount a bayonet or standard under-barrel grenade launcher. However, a suppressed 30 mm BS-1 grenade launcher was developed that fires high-explosive dual purpose (HEDP) grenades. The grenades from the BS-1 are launched by blank cartridges and the rifle is cycled manually in this mode of operation. The majority of AKS-74U carbines were manufactured at the Tula Arms Factory rather than Izhmash.

The AK-74 is also available in a “night-fighting” configuration equipped with a side-rail used to mount night vision sights (these variants, the AK-74N, AKS-74N and AKS-74UN are used with NSPU and NSPUM sights). The AKS-74UB (B – Bezshumniy) is a specialized variant of the AKS-74U, adapted for silenced use with the PBS-5 sound suppressor (used in conjunction with the subsonic 5.45x39mm US cartridge).

In 1991 the Izhmash factory in the city of Izhevsk began production of an improved variant of the AK-74 – the AK-74M (M – Russian: Модернизированный; Modernizirovanniy or "modernized") assault rifle. Apart from several minor production improvements the rifle also features a new synthetic stock made from a black, glass-filled polyamide that is shaped like the AK-74 fixed stock, but also folds like in the AKS-74. Additionally the AK-74M uses a reinforced muzzle device and dust cover. Each AK-74M is fitted with a side-rail bracket for mounting optics. The AK-74M was going to be adopted by the Soviet Union as the standard service rifle, and has been accepted as the new service rifle of the Russian Federation. Older versions of the AK-74 are also still in Russian service.

The AK-74 was also the basis for the new Russian family of Kalashnikov firearms: the 5.56 mm AK-101 standard rifle and 5.56 mm AK-102 carbine (both use the NATO-standard 5.56x45mm cartridge), 7.62 mm AK-103 assault rifle and 7.62 mm AK-104 (both chambered for the 7.62x39mm M43 round) and the 5.45 mm AK-105 carbine (adapted to use 5.45x39mm M74 ammunition). The AK-101, 102, 103 and 104 are destined primarily for export, while the AK-105 is slated to replace the AKS-74U with the Russian Armed Forces.

Ja ih obe preferiram u Counteru 

Najbolje o vrednosti AK-47 govori podatak da su za vreme vijetnamskog rata Americki vojnici masovno bacali svoje oruzije i uzimali Ak/47 kao primarno naoruzanje.

Ja M-ku.

Koristim srbijansku verziju 47-ice, sto ce reci M-70. Nemam nikakve zamerke i ne bih je menjao ni za sta na svetu pa ni za 16-cu. Pozdrav Amerima ali postovanje Rujama. Sve stoji i preciznost i kvalitet i kvalitet i zavrsna obrada,ali kada pucu ne cistis po 2-3 meseca a ona radi kao da je izasla iz pogona u tom slucaju su reci suvisne.
za nase koji su prekopirali Ruse...

Bila je emisija na Discovery-ju!!! Koja je najbolja puska na svetu! Rekli ljudi AK-47... a ja im verujem!!!



I ja!!
