I wonder what a sagia 308 will actually handel?? It can be done and Ive looked at doing it but if I were to do it Id want to make a bunch of them and I just simply dont have the funds for it or the insurance to sell them. I am starting to see more and more guys with CNC equipment talking about doing bolts and trunions. Turbothis ahs been playing with a CHC mill on the AK forum and he has made some cool looking stuff he was talking of doing 19mm trunions.

    Why not just get a Saiga 308 bolt?

    Saiga .308 bolts are in short supply. That is why I use a Bulgarian 5.45 bolt in my 7.62 NATO AK. Although I did have to open up the bolt face, and dremel the extractor a little.

    The 308 Saiga bolt is a different design. A standard AK bolt may hold up to a bit of shooting, but it might not. When firearms are proof tested they are placed inside a steel container.

    I would like to know where you heard that from. What are the sources for that information?

    The Russians published it a long while ago, when the 308 rifles first came out. It was before I had the internet.

    thats what I have read as well. i dont know the source but it makes sence that they would have not redesigned the bolt for know reason.

    Well...I happen to talk to some of their designers and specifically mentioned this to them on a side note and they were very quick to correct me that the pressures were fine and that the reason they added that extra lug was to try and squeeze a little more accuracy out of the .308. I'll find out more on my next visit with them, but until I can see the actual "publication" and from what source...which I will ask them about and have them verify...I am going to remain skeptical. I have seen a few .308 builds that do just fine on hot handloads without a third lug. How many does the M76, PSL, .308 M90s have???
