Ak restoration - gun restoration - soviet gun

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, the restoration process was not easy, because akm has pins inserted at 12 tons, this 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 maintenece, but this need really a restoration because he stay a lot of time in humid place. and was used for take every pieces. but at the end the restoration was end with a great result.
