What parts does the RPK share with the AKM? I'm talking about only the 7.62 version. Really wondering about the gas tube, gas piston, recoil spring, bolt/carrier........................TIA, Taipan :mchngun:
The RPK receiver is beefier with the additional material being on the inside. It reduces the width of the front and rear trunnions by about 1/20th of an inch.
The fire control group; bolt and carrier; return spring and piston; and gas tube are common with the AKM. The gas tubes I have seen have generally been ventilated. The front lower hand guard and retainer are different.
And obviously, because of the increased outer barrel diameter, the front site; gas block; etc. are not interchangeable.
