Tokarev SVT40

HELP !!!! Please !!!

Once upon a time there was a ridiculous regulation here in Mauserland called the "Kriegswaffenkontrollgesetz" which was intended to prevent military rifles from looking like - yes, you guessed it - military rifles.

As a result, things like the flash hider and bayonet lugs were cut off Enfield no.5s, No. 4s had the bayonet lugs on the barrel sawn off -etc. etc.

And the SVT40 had the barrel brake removed.

This nonsense is now past, and the barrel brake was put back on again some time ago, but only secured with a grub screw (weak) which was not even secured with Locktite or something similar (bad mistake).

Well, the inevitable happened - the grub screw must have loosened, and two weeks ago, when my friend arrived home: no barrel brake!

Needless to say, all plausible and even a number of implausible corners of his home and the range were searched. No luck.

So the appeal for help is thus: has anyone out there got a dimensioned drawing of the SVT40 muzzle brake? We could machine a replacement, if only we knew the dimensions. Tokarev spares are strictly unobtanium here.

Even the length and diameter would help in scaling up a good photo.

Thanks for reading this, and extra thanks to anyone who can produce dimensions or a drawing.

Wish I could help...
But maybe it would be important to know which type you’re looking for.
The one with 2 or with 6 chambers?

"The one with 2 or with 6 chambers?"

??? Its a rifle, it only has one chamber.

If you mean the slits on the muzzle brake, I think there were 6.

Muzzle brakes usually have expansion chambers inside as part of the design. The holes and slots are additional to the braking effect, directing the gases.

Yes sorry, I was meaning the slits.
There are two versions, one with two big ones and one with 6 thinner ones.

Aw, c'mon guys. I realize that probably nobody has a drawing of the thing, but couldn't someone at least measure the outside diameter of the muzzle brake? Please!!!

Patrick, I’ll ask the guys from my Italian collector’s forum. Maybe they can help.

Patrick,
What’s the drawing worth to you? I see these available for $40 or so.
I’d be happy to purchase one and put together a drawing for you.
I’m a draftsman by trade and this would be a pretty quick project for me.

Just reimburse my purchase cost and I’d be happy.

Let me know!

If some rough dimensions will do you any good, my six port has an OD of .746". the OAL of the wide part comes to about 1.922" if you don't count the .064" flange of the cap at the muzzle end, and the taper where the barrel flares to meet the increased diameter of the brake. The flare begins at about .421" forward of the front sight base. Reduced diameter section of the cap ahead of the flange is .352" long, and about .549" in diameter, not considering the flats for unscrewing it. ID of the muzzle end of the cap comes at .353". Distance from the front of the front sight base to end of muzzle cap is about 2.794". This may not add up perfectly, but I'm just working with the old calipers after a beer or two. Hope this can get you ballpark.

SUPER !!!!

With those dimensions I think I can turn up a plausible replacement.

Many, many thanks,
Patrick

Any time, amigo.

To my knowledge the SVT40 flash hider is an integral part of the front sight assembly and also includes bayonet lug, etc. Could it be that this part was cut off, the front part then threaded and a self-made flash hider fitted which is now missing?

Promo, the flash hider was indeed removed at one stage, in conformance with a ridiculous regulation (now repealed) that was intended to stop military rifles looking like ... military rifles.

Patrick, did you get some photos sent to you of a flash hider? I can take some photos of either my two port or 6 port if you wish, with a caliper next to it to show different thicknesses of the ports, etc.

Don't know about your import laws, but Liberty Tree Collectors currently has an SVT40 "flash hider muzzle extension" for sale for $35.00 US.

Thanks for the offer, but I found a very clear photo of the entire assembly that, together with the measurements from Low & Slow, enabled me to make a scaled sketch that should be quite adequate for the purpose.

I would then suggest you to buy a full replacement instead of making a DIY Bubba solution. A full replacement will cost less than to make the flash hider only yourself, and if you are patient, they are on eGun from time to time. Plus it is original.
