Unlike between AK-47 and AKM, the internal parts are fully interchangeable between RK 62 and RK 62 76, the only difference being the receiver. The total weight of the RK 62 76 is 3.27 kg. RK 62 76 - stamped steel receiver version, which resembles the RK 62 with newer style plastic furniture, but features a lighter weight receiver.the cleaning kit) in the tubular buttstock.Īll RK variants are designed to withstand the extreme environmental conditions of Northern Europe. A port in the shoulder pad allows storing items (e.g. This design made its way into the IMI Galil. This system reduces the number of parts, and simplifies manufacturing as well as assembly/disassembly. The ring's diameter matches the tube diameter, and it acts as the guide within the gas tube, the notches on the ring allowing excess gasses to be vented behind the piston head/guide. The gas piston has a cog shaped ring on the stem, behind the piston head. The gas tube is dove tailed into the front trunnion, and is a single-diameter tube, unlike the AK/AKM tube, which has a star-shaped cross-section to guide the piston while allowing gasses to vent behind it. The forward sight also has a mode for night operation. The rifle uses a "peep" diopter sight, which is flipped over to reveal the open tritium enhanced rear night sight. This is apparent especially in its accuracy, as it can frequently achieve less than one minute of arc. Aperture rear sight on a sliding tangent with flip tritium night sight, forward hooded post, 470 mm sight radius. The sight radius is doubled enhancing the accuracy along with the hammer-forged match CM barrel. In the Rk62 the rear sight is mounted on the rear of the receiver cover with tritium illuminated night-sights. The biggest single improvement, apart from the metallurgical quality of the receiver and the overall quality of the barrel, are the sights - most AK variants have the rear sight mounted on top of the gas piston housing on top of the receiver. The RK 62 is considered a high quality AK-47 variant. The upgraded model will be known as RK 62 M. An option for mounting a top rail for telescopic sights and night vision devices will be added to all rifles likewise the barrel will get an attachment point for tactical lights and lasers. The old tubular butt and leather sling will be replaced with a telescopic stock and tactical sling. In August 2015, the Finnish Defence Forces announced that they will gradually modernize existing RK 62 rifles. After testing by the military, the RK 60 was slightly modified (trigger guard was reinstated) and adopted as the 7.62 RK 62. The very first prototypes, closely modeled after Polish licence made AKs, had tinted birchwood stocks. It featured a metallic buttstock, a plastic handguard and pistol grip but lacked the trigger guard (it was hoped that it would make firing this weapon easier in cold Finnish winter when soldiers wore warm mittens). The RK 62 was produced in 1960 at the Valmet factory in Tourula and was internally almost a copy of the AK-47. Various foreign models were looked at, the Soviet AK-47 being the most important. The development of a Finnish assault rifle began in the 1950s. In addition to the flash suppression, the end can quickly cut barbed wire by pushing the muzzle onto a strand of wire and firing a round. One of the most distinctive features of the Valmet rifles, including the M62 and all subsequent variations, is the open-ended, three prong flash suppressor with a bayonet lug on its lower side. The RK 95 TP is a more modern, improved version of the RK 62. The RK 62 has a three-pronged flash suppressor, and a groove for a specially designed knife bayonet, which can be used alone as a combat knife. It is the basis of the IMI Galil, an Israeli-made assault rifle with many similarities. Between 19 350,000 M62 rifles were produced jointly by Valmet and Sako. The RK 62 uses the same 7.62×39mm cartridge as the AK-47. The RK 62 was designed in 1962 and is based on the Polish licensed version of the Soviet AK-47 design. It is the standard issue infantry weapon of the Finnish Defence Forces. The RK 62 (from Finnish rynnäkkökivääri 62, 'assault rifle 62'), officially 7.62 RK 62 and commercially M62, is an assault rifle manufactured by Valmet and Sako. 940 mm with fixed or extended stock / 710 mm with stock foldedĪperture rear sight on a sliding tangent with flip tritium night sight, forward hooded post, 470 mm sight radius
