Just a quick update:

We took apart 5 kits and sent some parts off to be nitrided and some parts off to be black ox'd. We'll see how they each turn out. The receivers should be done in a few days and we'll have a look see at them, too. Man, there are a lot of small parts to one of these kits, that's for sure. Lots of "handling" time.

I was just told that the receivers have been nitrided and are ready for pickup. We shall see how they turned out.

Is the idea that nitriding the receiver will harden the ejector cam surface and help keep wear down?

No. All the camming acting is done in the front trunnion, cups and rollers. Those are original. We simply made a new receiver shell that duplicates the original shell and weld, then copper furnace braze the trunnions, etc. to the new shell. Plus, the nitriding very closely duplicates the original finish.

To eject fired cases, the ejector sweeps across the face of the bolt and knocks the case out base first. See here:

https://www.falfiles.com/forums/show...3&postcount=11

The ejector is actuated by a raised section in the back half of the upper left corner of the receiver. Some have raised concerns that if the receiver isn’t hard enough that this raised section could see a lot of wear from the ejector. It seems like nitriding could help the receiver resist ejector wear.

It's gratifying to see that people are still getting use out of what I wrote years ago!

The geometry is such that I doubt you would ever wear out the camming surface in the receiver so long as its good steel.

But... good for nitriding. Can't hurt.

Well, I guess in my haste, I read your initial post incorrectly. I don't really have an answer yet, but will soon enough. And, yes, the nitriding adds a bit. That's some hard stuff.

ETA: Receiver shells are hardened. I have pics incoming, but they're not fully downloaded yet to show some nitriding. They turned out nice looking.

Simply gorgeous! Not that it matters but is the location of the serialling and manufacturing info finalized? Is this what a "production" receiver will look like?

woof, other than some fine tuning and interior stuff, this is what a final receiver will look like nitrided. And, yes, it is some fine work, if I say so myself. Yes, this is where the serial number and info will be located. We had to have special stamping dies made for this location.

Well, the first 5 prototypes are completed and ready for an endurance run on the range. Dang Sig's and their millions of small parts.

I've been following this thread since your first posts. Just wanted to add my name to the list of folks who admire your skills. It may be common knowledge here but I assume you are a gunsmith/machinist by trade? Just amazing stuff. I'd never be able to afford one of your rifles but I'll continue to watch your thread as long as you post updates...and maybe a video or two at some point.

Well, kroberts, thank you. And, no, I'm not a gunsmith by trade, but have been doing this type of thing for a looonnnggg time. I started out, like many, tinkering with k98's and almost immediately SLR's/FAL's.

And, if you think you cannot afford a complete built rifle, then maybe you could get a kit (about the same price as a nice FAL kit) and a receiver shell (coming soon) and build your own rifle.

We do have a few NOS barrels. Also, there will be new made barrels, but they are expensive to produce as they will be like the originals complete with the fluting cut in the chambers. This is not cheap. They are in the works, but that is a whole other project that demands a little time and a lot of money. Soon, though.

Actually what I meant was why were the kits imported without barrels? 922r issues?

Is a chamber like that broached?

No receivers, no barrels import ban. We're getting new barrels made soon and there is a minimum (expensive) order required to get started. This ball is rolling at a pretty good pace given what has been accomplished. And, yes, the chambers are fluted. We fired the 5 prototypes moments ago and all but one worked flawlessly. We think the bolt head gap is off slightly, but not a big deal. And, check out the first US compliant pistol grip! I know, I know...........awesome.

AGG is pretty close. The ones in the past sold for that and the ones that are being test fired now, some are spoken for already, with people in line waiting.

Or, you could buy a kit, a receiver shell from us, a barrel from us and make your own rifle for less, minus the hours put into it.

Does someone have a summary of the changes needed to get one of these running in .308?

In the HK roller-locks, the cartridge characteristics affect the locking piece that is needed. Is the fixed locking piece on the 7.5 bolt assembly ok for .308? Does the 7.5 bolt face work with a .308 case head? Does the recoil spring assembly work well without modifications?

I’m trying to decide if all the conversion work would be worth the benefit of not having to use the pricy and less available 7.5 ammo.

Vaughn, send me a PM so I won't forget.


thisismyboomstick, there are several mods that are required in order to get the .308 to properly function. I just test fired one of our conversions earlier in the week and it ran flawlessly. It took us a while to figure it out and that's how we're going to keep it for now......sorry. Top secret. hehe And, no, the bolt face has to be modified, first by laser welding and then by milling to another dimension, but it works perfect.

I was just looking at the pictures of your assembled rifles and noticed where the bipod hinges. Clever, not that we should expect any less from the Swiss.
