Anyone have experience with CNC Warrior VZ.58 barrel extension - NFA compliance?

[CitizenPete]

Does any one have first hand experience with the CNC Warrior Barrel Extension?

I would really like to know if this device causes any issues or interacts with the crown and affects anything such as the accuracy or ease of cleaning, etc.  It's kinda a commitment to pin/weld this on the end of your barrel.

For those of us with SA VZ.58 builds that include the original Czech chrome lined "SBR" barrel this little piece could be a great addition to permanently pin to the muzzle, and because its US made it does not effect 922R compliance and it brings the barrel to legal length for NFA Compliance.  (What else could it be for?)  This would allow us Czech barrel toting shooters to switch muzzle attachments easily at will, like we do with our VZ2008 rifles.

For a testing it myself,  I probably will temporarily screw it on to a VZ2008 (very tightly,  with a crush washer for the attachment, monitoring for loosening) to see what issues crop up and if accuracy or shot placement is effected. 

Just hoping someone else has done this already.

This thread from last year shows that Sheepdog was looking into it, but I don't see any followup on site. http://www.czfirearms.us/index.php?topic=66019.msg448549#msg448549

There are a few of people on this forum and one or two on the VZ Facebook group that have these and have not reported any issues.

I don't think the extension itself counts as an NFA part as its somewhat ambiguous as to whether it would be considered part of the barrel or a muzzle device.  I would think the md definition would only apply if the extension was all that was on the terminal end of the barrel...

1. The extension enables the owner to avoid an SBR violation, if permanently pinned on. -- Enables you to add or remove muzzle devices at will.

2. If the original pinned on muzzle adapter was US made, and not one of 10 listed foreign 922r parts on a firearm, then by removing the muzzle device and replacing it by pinning on a foreign threaded adapter to extend past 16" then you would immediately be in 922R violation.  forget about what may or may not be screwed on to it.

Good points.

But is the following strike what you meant to say?

B/c if it's not one of the compliance parts used, then it doesn't matter.  Right?

Good to hear.  I'm going to eventually remove the extender on two of my OOW rifles and replace with these.  Already ordered two.

Think of it this way... could it be any more detrimental than the muzzle extension that Czechpoint/CSA attaches to bring it to NFA compliance?  I was one of the first group of people to contact CNC warrior about these... they were made specifically to avoid an NFA violation, and allow muzzle devices, suppressors, etc.. to be attached.  I would have installed one on my original vz.58, if it wasn't for the bottom-feeding scum-bag that stole it.  Now I have a new CSA build with the NFA compliant barrel and threads.
