The 7.62×39mm (aka 7.62 Soviet, formerly .30 Russian Short) [5] round is a rimless bottlenecked intermediate cartridge of Soviet origin. The cartridge is widely used due to the global proliferation of the AK-47 rifle and related Kalashnikov rifles, the SKS semi automatic rifle, as well as the RPD and RPK light machine guns.
The M92 also features a shorter barrel. Unlike most rifle rounds which would otherwise experience a loss of velocity out of a shorter barrel, the 7.62×39mm round loses very little velocity when compared to a full-length barrel. This makes it an excellent round for short-barrel rifles.
Valmet M76 (milled) – a civilian semi-automatic variant of the RK 62, produced in .243 Winchester, 7.62×39 and .308 Winchester. Valmet M78 (stamped) – an export variant of the RK 62 76 with a strengthened front trunnion, heavier barrel and sight layout of the RK 71, which led to external resemblance to the Soviet RPK. Developed separately ...
The 7×46mm is designed to replace both the 5.56mm and 7.62mm NATO cartridges. It is low recoil and so can be used from carbines, but has long enough range to be used in machine guns and designated marksmen rifles. Its overall length has been optimized so that guns chambering it would be bigger than AR-15s but smaller than AR-10s. [11]
The 7.62 mm designation refers to the internal diameter of the barrel at the lands (the raised helical ridges in rifled gun barrels). The actual bullet caliber is often 7.82 mm (0.308 in), although Soviet weapons commonly use a 7.91 mm (0.311 in) bullet, as do older British ( .303 British ) and Japanese ( 7.7×58mm Arisaka ) cartridges.

The barrel has four right-hand grooves with a rifling twist rate of 185 mm (1:7 in), and has a muzzle velocity of 920 m/s (3,018 ft/s) using standard ammunition. Small numbers of this variant were made in order to show to clients for potential contracts that call for the purchase of the RK 95 TP in 5.56 NATO caliber in trade shows and arms ...
