7.62x25 Parts Kits

[CleptoVapor]

I unknowing acquired a bundle of some Czech steel core 7.62x25 on 8 round stripper clips recently. Pretty sure this stuff will tear through most of the Tokarevs I own. I was thinking of building one the CZ 26 or PPSH kits that have been floating around. Ive heard the CZs are a real pain to build but as far as i know its what this ammo was meant to feed. Are these still worth while projects?

I do not recall ever reading anything plausible regarding any Czech 7.62x25 milsurp that is loaded hot enough to cause concern that it may damage a TT-33 or one of its Variants.

I vaguely recall some Bulgarian ammo that should be avoided.

I have 11 TT-33s and Variants (I bought my 1st in Jul'03). I have never fired any Czech milsurp, only Polish, Yugo and Romy.

There is a fellow by the name of Clark with whom I am familiar from another site and recently noticed him posting here. He is The Expert on this subject. Hopefully he will see this Thread or I will recall his handle here.

I did a little searching to find out the why of this 8-round pistol stripper and came across this video:



This shows the 9x19 version of this subgun; it was also made in 7.62x25 for Warsaw Pact compatibility.

Thanks for the warm welcome, Im glad to be here finally

I have heard things going both ways on this Czech ammo some swear its perfectly fine to shoot others are claiming it cracked their slide and or firing pin but with the way C&R Milsurp goes who knows what condition the firearm was in.

I think building a sub gun for this ammo would be best I just don't know if its even a feasible project anymore with the ATF going after 80% or if its even safe to reweld one of those torch cut receivers.

My only experience in that regard involves building/assembling AKs, FALs on new-made semiauto receivers.

I imagine that the BATFE would not be very happy with you welding-up, "reactivating", a machine pistol receiver. As I understand it, their default has long been "Once a machinegun, always a machinegun".

In addition, if the CZ26 is designed as an OpenBolt device, you would probably have the devil's own time converting it to semiauto-only.

I couldn't find the post that I had read very recently from Clark. I will keep searching. <fingers crossed>

I’ve never built one of these, but my understanding is that open bolt SMG kits tend to be more difficult than your standard kit like an AK or HK type rifle.

The biggest problem is that unless you’re a 07/02 SOT you can’t build the gun back to its original open bolt configuration. Instead you have to take the open bolt internals and then figure out a way to convert it into a closed bolt operating system. This generally includes building/adding either a hammer and firing pin or a separate striker. Depending on availability of semi auto conversion parts, you may actually have to machine some of them yourself.

So in order to build one of these parts kits, you’re not really just looking at putting together a new receiver and throwing all the existing parts back in. You’re going to have to make some fundamental changes to how the gun operates. This is also why some of the commercially available semi auto clones don’t have a great reputation for reliability - tube gun SMGs are simple, but because of our laws around machine guns you end up adding a lot of complexity in order to build a legal semi auto.

Unless you’re knowledgable about those specific guns and the conversion process (and willing to jump into a build like that) I would probably recommend just buying an already assembled gun that shoots 7.62x25.

Oh well. As I understand it the ampersand prefix will alert him to this Thread.

At least for the CZ there are conversion kits to change it to semi with some modification to the standard bolt. Im currently working on getting 07/02 SOT status to switch out my 03 FFL but who knows how long its going to take that process to complete if ever so maybe one day they can be restored to their former glory. Ive been having issues with finding new receivers for either of those builds as last i heard they were being discontinued. so the thought process was weld it up if possible to safely and install semi auto conversion kit until full auto can be legally restored.

Yugo m57 will shoot them just fine.

I only shoot Bulgarian late 50's ammo out of my Polish Tokarev. I have clocked a lot of 85gr bullets at 1,880fps. 1 out of 3 have cracked necks. But, the pistol shoots them without any issues. This is one of my favorite guns to shoot.
