The sight height above the bore axis is also approximately 3 mm (0.1 in) higher than the AK-74, due to the combined front sight/gas block, rear sight configuration. The AKS-74U has a different rear sight composed of a U-shaped flip sight on the top cover instead of the standard sliding notch tangent rear sight.
It was derived from the AK-74 rifle, with modifications that mirror those made to the AKM to create the RPK. The RPK-74 also uses a longer and heavier chrome-plated barrel, which has a new gas block with a gas channel at a 90° angle to the bore axis, and a ring for the cleaning rod.
The saiga most resembles an AK-74 and the AK-100 series of rifles. It includes a stamped receiver, and 90-degree gas block unlike the AK-47 which has a milled receiver and 45-degree gas block. The use of a third trunnion rivet gives it resemblance to the AK-100 series of rifles Russia is currently exporting.
Diagram of long-stroke gas operation system Long stroke gas piston, from an AK-74. With a long-stroke system, the piston is mechanically fixed to the bolt group and moves through the entire operating cycle. This system is used in weapons such as the Bren light machine gun, AK-47, Tavor, FN Minimi, FN MAG, FN FNC, and M1 Garand.
E2S Shorty AK [7] - Shorty variant with 14.5-inch carbine SBR barrel with an AK-74-style muzzle brake permanently welded to the end to increase the overall length to 16 inches. E2S Dissipator [7] - Variant with a Bushmaster-designed 16-inch "Dissipator" barrel. This mounts a false gas block with a front sight at the 20" position with the real ...
The most easily recognized AKM feature is the gas block design (45 degree versus 90 degree). Incidentally, although the gas block is purely AKM, the gas vent in the barrel did change to a 90-degree design to minimize bullet shearing (a problem with early Soviet AK-74s with 45-degree gas blocks).
The Tantal is a selective fire, gas piston operated weapon that taps expanding exhaust gases off through a port in the barrel to a gas cylinder above the barrel. The barrel is locked against its longitudinal axis by a right rotating bolt. A spring extractor is contained inside the bolt head, and a fixed ejector—inside the receiver housing.
The milled gas block is flat on both sides and, like the Type 58, has a sling swivel that extends outward from the left side. [3] The folding stock variant of the Type 68 has the Soviet underfolding design with stamped steel struts and buttplate. [3] The rear sights are graduated to a distance of 800 meters. [3]
