Muzzle brake?

[DJokr]

What has to be done to replace the barrel extension with a muzzle break?
Has anyone had it done?

DJokr -

As I understand it, 58's with detachable muzzle breaks are illegal in the USA because of Federal barrel length restrictions.

Additionally, a Czech made muzzle brake may (and I'm not sure of this) run afoul of 922r.

If a muzzle brake passes the Federal barrel sniff test, it would have to be pemanently

Attached to the barrel.

Whatever.  I would call up Czechpoint and get the down and dirty, or send an email to Our Man Dan,

On the sub-board here.

ps -  Look up at the lead thread on the VZ58 mother thread here.  It is all about 922r and other good stuff,

and, yes, the muzzle extension is required by 922r.

ORF has a US made copy of the muzzle brake.

I understand the muzzle breaks must be permanently attached, I just need to know how to remove the extension so I can tell my gunsmith.
Thanks for the link tf34mech.

I checked out the thread and it list the barrel extension ( non US made part) but doesn't say anything about the break.
Thanks salskov

The muzzle attachment (or muzzle break) is a part counted for 922r.  There are two welds through the muzzle attachment and into the threads of the barrel.  Once the paint is removed on the muzzle attachment, the weld areas will be visible.

what everyone already said.  A friendly grammar note.  It's a muzzle brake. Your rifle is not broken. 

[DJokr]

Thanks dusty10, on the grammar note, I noticed some web sites spelled it "break" not "brake".
Now that I know the extension is welded on, how do I get it off? Do the welds have to be drilled out?

[dusty10]

I am no gunsmith by any means but I think you would need to sand paint off to reveal welds through brake into barrel threads then drill out welds and hopefully the extension would twist off.  Why not just by a new barrel and replace the old one.  Or buy a build kit and build one from the ground up as you like.  Be careful you don't get into any 922r issues.  What does Dan at CZechpoint-USA say about all this?

[CzechPoint]

The weld areas need to be carefully removed down to the threads.  A rotary tool with a grinding stone is a good way to do it.  The threads will need to be cleaned up so the new muzzle attachment screws on easily (of course it will have to be permanently attached to avoid illegal SBR issues). 

I would not swap barrels as it is usually extremely difficult to remove the barrel from a D-Technik receiver.  More difficult to remove than from original receivers.

I would take that to mean it is extremely well built.

[dusty10]

My first inclination was to take a grinder to it but I guess I was assuming he wanted to save the original barrel extension.  And yes, these CZ-USA vz-58's  are built like a tank. 

[CzechPoint]

It would be extremely difficult to save the original muzzle attachment.  After you're done, it'll be trashed. 

D-Technik/Czech Small Arms uses a special technique to press the barrels into their receivers - I can't reveal the "secret sauce"

Funny!

Does modifying your break or site base void the 5 year warranty? To bad there wasn't a shop to install a bayo lug site base in the states after they were imported. Wonder why the Czech army choose a 15 inch barrel if they chose a 16in we would all be happy. A vz58 in the us with lug and removable breaks/ silencers/ hiders mmmm.... vzzzzzzzzzzz  owell cant have it all, still the best and lightest 7.62x39 rifle available, i cant stress how much of a plus it being light is.

[DJokr]

I was wondering about the warranty too, if it does then I can wait. It's starting to sound like a pricey modification.
