So, I wanted to know, are ORF recievers good to go? This rifle was built a couple of years ago on an Ohio Rapid Fire receiver, Bulgy parts kit with original barrel, 922r Compliant with trigger group, pistol grip, gas piston and reciever. Owner claims he parked it then sprayed black paint over that. It IS riveted.





Whats it worth?





linkage.

If it looks good I would say it is worth what he is asking.  Maybe try to see if you can put a mag through it.  (one of your mags if possible)

ETA: no experience with ORF recievers but I have dealt with them and like them as a company goes.

Find out if ORF fully hardened their receivers or just the pin holes.

If not fully hardened, I would not pay much more than the worth of the parts in it.

If fully hardened, then $500 seems fair if it shoots well and the rivets are well done.

I never knew that Ohio Rapid Fire made receivers for AKs other than the Galil receivers that had issues.

They usually used Ohio Ordnance Works OOW/ITM receivers on their stamped builds as far as I knew.  Those receivers only had the trigger and hammer axis holes spot treated.

Okay, my bad it's a Ohio Ordnance receiver.



This is the process they describe
Heat treated. Trigger, hammer holes and
ejector are heat treated, then the whole receiver is drawn down at 575
Degrees for one hour. The receiver is now heat treated but not brittle.
If you heat treat the whole receiver, the minute you quench it––it will
warp.


Which is to say it's spot treated. And they claim that everyone elses receivers are warped. Goody. I may have to pass.

ORF did a small run of Type 2 AK receivers as well as a milled AK74 receiver that was their own design (rare I think, I've only seen one in person and one for sale online).  This was around 2005 or so.

Heres a pic of their AK74 receiver.

Now that you posted that pciture I remember seeing those, not that I would want one, they look hideous.

That means only the holes are really heat treated. Ejector too. The rest is basically mild steel. If you twist or bend it, it will stay bent!

That receiver is about the same as making one from a flat yourself.

NDS does full heat treating with no warpage. If you get it, I would rebuild it on a NDS or any other fully heat treated receiver.

You don't want to trip and land on your rifle and get up and find it bent. A full heat treated one will spring back.

Over the course of this year I bought four new NDS receivers to rebuild four buiilds I did on flats some years ago. Nothing wrong with my flat builds. I was proud of them. But there was no way I could fully heat treat them as a home builder. So I am slowly re-doing them on NDS's. Demilling the old ones was a real eye opener. Tearing those flats down was way too easy. You easily bend the material. Only the rails and holes had been toughened with heat treating. Just not the same as de-milling a tough original receiver stub or working with an NDS.

There is a builder on the AK Forum who offers fully heat treated receivers made from AKB flats. These are damn good flats. I used them myself. Funny.... He gets them fully heat treated with no warpage.

Personally, it would only be worth the value of the parts to me, since I would want to rebuild it on a better receiver.
