Default AK disconnector sizes (normal vs. narrow) ?

hello friends!

im looking to make my REPLICA (that's being used for instructions) a full auto - and for this i want to use a full auto disconnector (already checked for the laws etc).
it already has the auto sear and everything needed - the only thing that left is to replace the semi disconnector with a tailed one.

my question is (since the sizes might not be identical in the replica) - whats the thick of a regular ak disconnector, and whats the thick of a narrow one? i couldnt find the info about it and i dont know which of them should i get.

P.S my disconnector seems to be 7mm wide.

P.S.S - if someone has some full auto disconnector that he has no need for, i would be very happy to be its' new owner

thanks!

are you doing this on a chopped receiver middle section?

I think they may be the same

there are at least 9 disconnector options.

There is no way to legally instal the auto sear in an in-tact receiver, without registering it as a post-86 dealer sample machine gun, which you can only do as a licensed machine gun manufacturer. So saying "I checked the laws" and "I already have the auto sear" does raise some eyebrows. I am an instructor for the Forensic Firearms Examiner Association and use mock-ups from cut receivers for training aids. If this is what you're doing, fine. I also have registered full-autos. But if you have an in-tact receiver, don't drill that hole!

Within the context of your question, examine the inside of your trigger (trigger and disconnector must match). If the recess for the disconnector spring is centered, it uses an AK-47 type disconnector. This is the same width as the inside walls of the trigger.

If your hole is off-set to the left, it uses an AKM type disconnector with the rate reducer/anti-bounce device and is narrower to allow for the rate reducer. I don't have a dimension for you, and it doesn't matter - just look at the part. If there is relief cut on the tront right of the disconnector, it is the narrow one. No relief cut, and it is the wide one. You can also use a spacer/washer to fill this gap. Some make it from the coils of a spring. Dome from parting a center support (4mm dia).

There are two versions - large hole, like the late Romy, which uses a sleeve to hold the parts in place, and one that does use the sleeve - just the axle pin.

thank you for your time and answer, friend.
i do not live in the US, and the point is that this replica is a complete gun, that is being used for training for everything (from learning the FCG to full disassembly).

just to make sure:
the FCG is a little different from the regular, real AK ones (for being accepted by the laws) - the hooks and the trigger itself are not the same unit and the springs are different. other than this, it operates normally and disassbles almost the same. all the rest (besides bolt) is identical. also, the barrel is blocked and holed and some components are not in the exact size as the real thing (by milimeters), and the gun (which doesnt need to be registered at all) is fully legal to have, and no matter if it has / has no 3rd hole (btw, it has one rfom the factory, and also an auto sear pre-installed) - since it cant be converted to a real firearm and does not count as one.

anyway, for the question - ive asked about the sizes because the FCG in this replica is different, and this is why i have to get the sizes and can't trust identifying the FCG by its "type" - its not identical to the real one

ps - the fcg is large holed one, just like the romy.

attaching picture for reference (with no springs. the little shiny thing in buttom is the top notch of an axis pins retaining plate):

As you've seen previously here, nobody seems to know the country code for Israel, or expects an Israeli member.

Good luck with your project

IL is the country code for Israel, as well as the abbreviation for Illinois.

anonimi8989 has asked questions and made statements here before that would put him in an "interesting" position were he living in the USA.

nvm. not a big deal..

thanks nalioth, for wishing me luck with the project !
do you have some disconnector (out of a gun) that you can measure for me, please, and let me know the type of it (wide / narrow)? it seems no one actually have the sizes..
only if you have one out of a gun, and theres no need to take it out etc.

thank you!

Thus explaining the comment on country codes. I get it now. (grin)

at the widest part, the AKM narrow disconnector is 6.75mm.

sorry, bro, but I've been really busy.

The inside width of the trigger is 9.5mm.
This means that whatever goes inside the trigger cannot exceed 9.5mm. For AKMs equipped with the rate reducer, the narrow disconnector (6.75) + the portion of the rate reducer that straddles the trigger (2.75mm), total 9.5mm. The rate reducer is slotted and the majority or its mass sits to the right of the trigger.

I'm assuming that you only care about the part of the disconnector that sits inside the walls of the trigger. This is an important distinction, because the disconnector claw portion is the same width on both the AKM and the AK. The AK has a flaring at its base to fill the trigger width. The AKM is narrower and offset at its base to allow for the rate reducer to fit

Most Romanian are of the type that takes the rate reducer. I susp[ect that all of the "G" (civil guard) were. These simply had the tail of the disconnecotr shortened to fire semi in both semi and auto positions. But I have seen some older Romy ones w/o that the rate reducer and with a wider disconnector.

all the wide ones are the same width, although there are different contours to obtain that width. They fill the trigger.

I have an AKM trigger & narrow disconnector with 5mm hole, I need to find a spacer that is 2.75mm wide and a 5mm hole to use for a spacer. Does anyone have any suggestions or where I can find this?
