Ak 47 restoration - gun restoration - soviet gun

In this gun restoration video, I restore an ak M. I bought this gun in an arsenal in the Czech republic, I already intended to restore the gun, but the restoration process was not easy, because AKM has pins inserted at 12 tons, which means that a large hydraulic press is needed for the restoration of this gun. However, I managed to complete the restoration and make this Soviet beauty work perfectly.
This gun is built in Izhmash in 1971, normally he required maintenance, but this needs really a restoration because he stay a lot of time in a humid place. and was used to take every piece. but in the end, the restoration ended with a great result.
