Default Yugoslav 3 rivet grip nut plate?

Sourcing one of these and a Yugo selector is proving difficult...

If anyone may know where either of these are available and could point me in the right direction I would be much obliged.


Does anyone know if I could just use one of the various 3 rivet grip nut plates for milled receivers?

The Yugo pattern holes are already located and drilled in my blank.

Are there no other selectors that will jive with the Yugo angled selector notches in the receiver except Yugo?

I’m pretty sure the T3 nut is the same as Yugo nut
You want to get a Yugo selector
I think I saw one on eBay two days ago.

The Russian, Polish, Bulgarian, and Hungarian Type 3 grip nut interchange with the Zastava grip nut. Same hole pattern and rivet diameter. I am fairly sure that Apex has these.

Apex has one (01) piece in stock: https://www.apexgunparts.com/polish-...stud-good.html

The Zastava selector is unique. Apex just listed a group of M70 kits and there may be a selector available - you'll have to call. The super-rare selector is the Zastava unit for their underfolding rifle. Me? I would place a WTB thread in the Marketplace.

I think the rivet holes are the same, but I think somebody thought they found that the angle of the threads was a bit different.

I can't see it making much difference if the angle is slightly different.

It is just pulling the grip tight up against the flat bottom of the receiver.

No - same there as well. I thought they were different but they are the same 24-degree angle measured from vertical. A murky digit on the blueprint caused this error.

The Zastava unit has an additional rivet hole to secure it to the butt block of the stamped rifle. I'd venture that the "extra" holes in the Zastava are left over from the M64 design that used a lower tang as did the Type 3.

A customer once brought over one of the later Arsenal milled rifles for installation of the lower tang. The Arsenal pistol grip nut on this rifle did not have the second hole for the lower tang and I drilled it as an assembly after setting one (01) rivet. Once finished it was exactly like the Type 3 buttstock mount.

On the AKM style M70's and on the M92, the rivets get support washers under them inside the receiver to compensate for the thinner / weaker receiver.

Yes, ha ha, it looks like a transmission chain link on the M92 I have from one of the mil-spec kits imported several years ago. When I unpacked the kit parts I found a few M5 socket-head cap screws and I found that "chain link" and thought it was also spare hardware until I measured it and compared it to Metric transmission chain standards. I kept the "chain link" with the kit and long before I assembled the kit it dawned on me to "look again". I could see it was a shim to make up for the "missing" 0,6mm.

I placed the socket-head cap screws in the machine shop's general fastener stock.

I've never seen the AKM-style M70 except in photographs.

I thought you made two different bucking blocks for Yugos and T3s. Was the difference based upon the perceived angle of the threaded hole?

Dumb question. If the angle is the same, then why does utilizing a standard Bulgarian pistol grip on a Yugo result in warpage of the pistol grip screw? I never bothered to measure the angle, I just noted that my screw bent after I switched the 92s grip.

I did at one time, and then I found that the angle was the same.

The AKM-style grip used on the AKM and AK74 has an angle of 20-degrees rather than the 24-degrees of the Type 3/Zastava riveted unit. The different pistol grips have this difference as well.

Makes sense. Why waste time measuring angles when someone here already knows the answer.


Also missed the reference to "milled", was too busy working and irritating people at the time of the post.

Put an original T3 grip on my 16” M72 that was built w the Yugo nut that came in the 72 kit.
No difficulty / angle difference what so ever
