VZ2008 SBR

[ncz]

Hi guys.  Came over from the files due to recommendation of a few members there.  I've bought a couple of these rifles, love them, and want to turn one into a sbr.  Have read a few threads from seanc and others.  Guess I want the cliff notes version. I guess the cliff notes of the cons.  What's the optimal length?  Looks like forced march welds combo FS/GB's, any sources for those?  I want to tackle it myself as I am fairly handy and have access to machining equipment and someone who knows how to run it.  It will also get a can, anything to worry about there?  Please throw any other advice.  Thanks for the help in advance

Buy a Czechpoint pistol and go from there...  Chromed barrels are a dicey to cut down, requiring expensive and costly tooling, and require removing the barrel from the receiver anyways...  So there are no cost savings w/ DIY.

I believe their pistol/CSA carbine has no changes to gas system, though it might -- especially at the gas block/gas port diameter.  And you'd need to disassemble the carbine's gas block to measure those anyways...

CSA has pics of the various lengths they use/make the VZ58 on their website -- Czechpoint has at least the rifle and carbines on theirs.   

Jim Fuller at rifle dynamics (principal of THE ak experts) doesn't recommend 7.62x39 out of anything less than 10" -- see his 10" 7.62x39 Krink listing for why; the youtube is no longer where he discusses an 8" 7.62x39 misfiring into his truck bed, penetrating that, but denting and not penetrating his cab body led to that conclusion (a lot of his customers are private security guys in the middle east and other trouble spots)...  So that leaves the 12" carbine configuration as best that's available.

Also a good read about SBRing 7.62x39s: http://demigodllc.com/articles/7.62x39-improving-the-military-standard/

CNCWarrior also just made their VZ available again. If I had the money I would buy one, but that is not the case. They have their fake suppressor attached to make it 16". By what I hear they make a good product.

Thanks guys, this is what I am looking for!  So conscientious is that I should buy a pistol and go up from there.  I had hoped to cut down one of my 2008's, crown it, thread it and be gtg.   And add the combo block, looks like not so, anyone done this?

Sorry, missed your post before today.   If you are going to keep your rifle in its original configuration and not start swapping parts out, then cutting the barrel down (after getting your ATF Form 1 Tax Stamp) is prob the easiest and cheapest path.

As far as length:  If your sticking with 7.62x39 (and not looking for .223) then cutting the barrel down does not dramatically effect the bullet velocity like other calibers. Check out the barrel lengths offered on Czechpoint USA for the pistols to get an idea.  Personally I would go with the carbine length short barrel.  I recently sold a Bulgarian milled AK pistol with a under 10" short barrel because it was unruly and a flame thrower. Hated it.

From my research, 12.5 inches seems to be the optimum barrel length.
