Just Wondering

[lobo]

Has anyone attempted a MAC in 7.62x25 Tokarev? Ballisticaclly it's about the same as a .357 mag and is a rimless and bottle neck case. I like the round and it's cheap. Just asking if anyone has been dumb or venturous enough to try it.

I'm pretty confident I've heard about this before. might have been on the ar15.com board though. seems like someone did it exactly for your reasoning. like they had a shit ton of it or something.
I know that doesnt help much, but maybe give you hope and someone with more specific knowledge will chime in?

You'll not only need an upper with a Tokarev barrel, you need a way to feed the cartridges to it, and that means modifying your lower. You'll need a Sten magwell and modified Sten mags. Do a search... it's been discussed here before. The round isn't *that* cheap... it's certainly more than 9mm.

Interesting. I was just discussing that today with the guy who made a half dozen of the barrels. Perhaps he’ll weigh in.

Concorde is absolutely correct on all counts. To start, you’ll need a Sten mag well conversion and Sten mags for the longer 7.62x25 round. You’ll also need an appropriate barrel. There was a time not many years ago that surplus ammo was widely available and cheap. That’s no longer the case, and I can’t imagine this conversion would be worthwhile today.

I agree that it is an interesting round. I bought a conversion kit for my BRP because I thought it would be fun in a FA. Since all the cheap surplus ammo has disappeared, I have never even put it on the weapon. Perhaps someone will import a bunch of cheap surplus ammo and I'll take it out, but for now it just sits on the shelf. And before anyone starts PMing me, no it is not for sale.

I asked this question to someone on another board a long time ago. For a M-10 cz 26 mags work. They fit in the magwell and there is very little adjustment needed. With those mags you need to find a tok barrel to fit in an upper then make feed ramp right

The guy used the set up. I found the mags and didn't find source for barrel, then quit looking due to the surplus ammo drying up. Without the surplus ammo people were trying getting rid of M16 conversions in tok but never saw anyone else with a Mac conversion. I would recommend not doing unless you know where a large stash of cheap ammo is.

There have been a lot of threads on this, but I plan to seriously investigate the possibility of a 7.62x25 upper for my 45 M10 when the transfer is approved. I was also told that sa24/sa26 magazines will fit in them, and I have several from sa26 parts kits.

Hmmmm

Cz26 mags will work with tinkering in the m10. You will also need a TASK or Lage max10 upper. The round is to hot forthe standard bolt weight (at least the eastern european stuff).

Shameless promotion...
The two pound CF-W bolt for the M-11/9 would be worth looking at for use with the 7.62x25 round. No TASK conversion required.

You guys are right, the cheapest I found the Tok was 0.37 a round. I have a ton of it, but once that runs out it's not cost effective for a conversion to be developed.
Here's a semi (yes, closed bolt not open bolt) tube tok pistol I built from a kit using some PPS-43, PPSH-41 parts and an AR-15 fire control group. The kit called for all PPS-43 parts, but 43s won't take a drum and I had tons of 41 parts sets laying around so I bastardized it to take both sticks and drums. Haven't even range test fired it yet but did test fire it in my house through 4, 3" phone books at point blank...went thru three of them and into the 4th. Cycles manually good on drums and sticks so if it passes the range test I at least have something to burn up my ammo. The exquisite finish is Home Depot BBQ grille paint lol.

Max-31 should be viable with tabbed Sten mags, but the cheap ammo dried up long ago. I remember royal tiger when they first opened had it for .05c a shot. Always regretted not buying.

So this thread got me thinking and I realized I have an old Tokarev barrel for M11/9, a Max31 Mk1 upper, and a bunch of old Sten mags in addition to some unused Concorde tabs.

Hmm...

Looks like 7.62x25 would fit in a Sten mag if you removed the rear reinforcing rib and brazed/spot welded on a flat backplate. I don't have any PPsH mags in my possession, I wonder if one could thin out the front-to-rear dimensions enough to fit the 1.5" magwell on the Max31 similar to Concorde's Sten mag conversion. Anyone tried either of these?

Hmm...

Good, creative thinking. There's a lot of talent on this site.

Ppsh mags will not fit, they are 1/8 or 1/4" to large

In the max31 the standard bolt is to light. You will need to use the cfw bolt. I ran some 30tok through the max31 and it was pretty hard on it

 

[DistalRadius]

Sounds like it wouldn't be possible to remove enough material. What mags did you end up using for running Tokarev in the Max31?

 

[chili17]

STEn

 

[DistalRadius]

Got any tips you'd like to share on converting a Sten mag to 7.62x25 before I start hacking?

 

[chili17]

I just milled through the spot welds on the on the top part of the mag cover. Once the mag cover was removed I inserted a tapered support in the body of the mag, threw it in the vice and milled out the center rib from the last witness hole to the top. Put the mag cover back on and weld in place

Thanks Chili.
