View Thread: ORF Galil Receiver Ejector Rail Hardness?


millersm99
Took my new Galil build to the range today. New ORF receiver. Ran great with Wolf, and brass cased ammo. Put around 60 rounds through it. Took it apart tonight and noticed the ejector rail was worn a bit. Much more than I expect for only 60 rounds. Has anyone taken a close look at theirs?

I'm a bit worried as to the longevity of these receivers. If the ejector wears down WTF do we do then?

Ir seems that some ORF receivers are a bit soft. You might try heat treating just the ejector with a torch. Heat it and quench it in a bucket of water might do it. If it's soft I doubt you can make it any softer. The milled receiver will draw the heat from area quickly though.

My Galil was put together by a builder. I now have extensive experience with the Galil and how they are built. I'm here to tell you that the ORF receiver is a good receiver. It high quailty steel and is fairly dimensionally sound but ORFs quaility control when it comes to heat treating is piss poor. Before I built my Galil I wanted to make sure that the receiver was viable and would last as long as it possibly could. My builder had the receiver tested and the receiver was harder on one side than the other. These receivers should be at least 40 on the rockwell C-scale (rates hardness of steel). One side of my receiver was far below this (the other side was harder but still not to spec). The builder I used also told me about ORF receivers that were in the low thirties on the C-scale (way to soft the ejectors will round off or bend or the rails will wear prematurely). If I were you I would not fire the gun anymore. I would find an inustrial district in your area. Find a good metal shop that does heat treating. I can almost guarantee that you can find one locally or maybe you know somebody. They can test the receiver for hardness and heat treat it for you. I got my receiver treated for about 20$. They took up to about 45 on the rockwell (milled receivers can be a little bit harder than stamped receiver becuase of their rigidity and carbon content). My galil functions flawlessly and I have seen no discernable wear after over a hundred rounds of Partisan 75 grain. Be weary though if your receiver becomes to hard it can crack and cause bigger problems than you already have. I would advise against doing it yourself for that very reason. The biggest headache will be removing your stock and barrel. I think you will find that there are a lot of people that have the same problem with the ORF receiver. Spread the word. Its a good receiver but you just have to watch that heat treat.

Who was your builder?

Peice of History Fireams, they were extremely patient with me and he did an excellent job on the build. He was very flexible and kept in constant contact concerning how the build was going. I'll definately use them again and I would strongly encourage anyone to use him for any kind of build. Check out his site.
