Yugo trigger guard question

allesennogwat · 04-20-2010, 03:23 PM

I need to know if the four front rivet hole locations (M70) are the size and spacing as an AKM and if they are the same distance from the magwell opening. I know the rear is riveted through a milled type pistol grip mount. I gave away the only M70 trigger guard I had. It was from a stamped underfolder. I want to know if the M70 selector stop is 100% interchangeable with an AKM selector stop plate. I'm making a Yugo template but the receiver stub doesn't have the section where the four rivets go at the rear of the magwell.

I am using a standard AK-Builder AKM flat for my milled Yugo kit from CFS that came with the trigger guard. Everything fit fine. I did have to do a bit of tuning for lockup but that was the build where I made the front trunnion out of a stub. As a twist, I used a Romy pistol grip nut and bolt instead of the Yugo unit.

For the Yugo trigger guard to fit the AKM flat, it must have the same rivet spacing and I simply used a short rivet and put the Yugo guard straight to the receiver's rear hole.

Let me see if I can find and compare a Yugo to a Romy selector plate. I'm not sure if I can find a spare Romy TG assembly right now.

Thanks. I mainly need to know if all four front rivet holes are exactly the same between the Yugo and an AKM trigger guards. It may or may not matter but I want to compare the stamped Yugo M70 receiver parts to the standard AKM.

ronin · 04-20-2010, 06:30 PM

I can only compare of the milled M70 kit. Do you want to wait and see if someone with a M70B series can answer your question?

allesennogwat · 04-20-2010, 06:33 PM

Thanks. I'm expecting them to all be the same. I don't think milled or stamped or Yugo would change those rivet locations. Did you milled receiver Yugo trigger guard go right on the AK-Builder flat?

allesennogwat · 04-20-2010, 06:42 PM

Well I just found the rivet spacing the Russian manuals. It looks like all Russian AK's have the same trigger guard rivet spacing. I hope Yugo's are the same. I don't think that would be something they would change but the Chinese did to use fewer rivets.

I just compared a virgin Yugo TG and and an East German AKM TG. The hole spacing is the same in all respects. Hope that helps.

allesennogwat · 04-20-2010, 07:08 PM

Thanks. I thought they would be but that was one Yugo measurement I didn't have.

Hole spacing is the exact same...BUT the rear leg of the Yugo's is SHORTER(the thickness of the selector stop) than a standard AKM.

they'll work, but you might need to bend the TG slightly to get the hole to line up and the tang to sit flush to the Gripnut.

valleyrat · 04-21-2010, 11:45 AM

....or add a spacer.

the AKM trigger guard is LONGER, due to the rear tang matching up flush to the receiver.

Yugo's are like a milled TG, in that they are flat across the bottom, so when it's placed on top of the Pistol grip mount, it is level across the "bottom" The Grip mount rivet location is the same thickness of a Selector stop.

the AKM TG will be long the thickness of the Selector stop.

I'm just a picture nut I guess.
Anyway here's one for reference. Always helps me to get a grasp
on something with a pic.
Id say if needed go ahead and heat the trigger guard there at the rear
re-bend it and shuffle it to fit. It's not that thick in the M-70 nut plate
and may be tweakable.
If not , just do as ronin just did and put a regular AKM nut on.

Lamont · 04-21-2010, 03:12 PM

I"ve also had good luck relieving the BOTTOM (receiver side) of the PG mounts and placing the TG between the Mount and Rec. It't snot "Correct" but it's secure, and works just fine.

allesennogwat · 04-21-2010, 03:47 PM

I'm drawing a receiver template for the Yugo. I'm not trying to use a non-Yugo trigger guard on a Yugo. I needed to know if the front four rivet holes were the same because I have those specs already. I do have a Yugo rear stub but I gave away the trigger guard from it.

allesennogwat · 04-21-2010, 03:49 PM

Is there a reason for the two holes on each side of the pistol grip mount? Does the pistol grip have studs that go in these holes?

Lamont · 04-21-2010, 04:15 PM

yugo Rivet locations are the same as any other AK/AKM. EDIT: For TG.

the 2 holes in the Rec are for taking the underfolder apart. When installed correctly, the pins are flush with the underfolder stuff. Drilling those holes allows you to drive the pins out from under the rec.

allesennogwat · 04-21-2010, 04:31 PM

That explains why they retained the milled receiver pistol grip mount. Those holes would weaken the receiver too much for the square hole pistol grip nut.

I added a spacer under the "tang" rivet hole and it worked fine on an AKM receiver, didn't seem like a serious issue to me.

I think the two holes are there to help in removing the UF stock

AKBLUE · 04-26-2010, 05:30 PM

I do not think there is any difference in the trigger guard configuration. There are AKM's that use a reinforcemet plate at the rear (underfoklders in particular)as well as the grip screw trunnion on the Yugo and the trigger guards are the same.
