You would end up with a gap at the trunion and the area for the center support is a issue . it is best to just make a new one out of some correct metal. I milled my first one from solid bar stock as it was all I had on hand. but for the rebuild I will use sguare tubing cut into angle per HC pookies idea else were in this sight. air craft spruce has it.
Would it be possible to use a standard AK47 ejector, but just set it further back in the reciever for shell clearance, or will a whole new ejector rail have to be made/manufactured?
