Hello all just picked up an ak47 Saiga I'm looking for an Arsenal 7.62x39mm 16" Barrel 23mm Trunnion Block to put it back to original state. Currently configuration had an RPK barrel on it. Also noticed that the picture tube will not lock down properly any info on this subject will be greatly appreciated. I cant figure out how to attach pictures other wise I would do that. Can email or text pics if needed. I'm located in Indiana

Definitely going to need pictures to show what you're talking about. I can decipher some of what you said but still not sure if you need a barrel or a trunnion, or what.
