We all know that there are steel AK mags modified to fit the VZ (but no BHO).
Well, apparently there are all also VZ 58 steel mags that activate the BHO. They are made by KCI and Wolverine up in Canada sells (but they dont' ship to the US so forget about it...).
http://www.wolverinesupplies.com/details/9057/KCI-CZ-858-762x39-530-Mag-Newly-Manufactured.aspxThe mags are made by KCI (Korean) and as you may know they get a variety of reviews, some bad, some positive, some good enoughs... Glock and M1 carbine are the areas where I'm familiar w/ their reputation. Possibly different on other platforms...
Regardless, the Canadians have some reviews over on Canada gun nuts. I created an account to follow their VZ content and their full feature thread regarding steel VZ58 mags is here:

If you can't access, this should work:

*I wanted to mention as I learned all of this while researching a steel magazine that matches the KCI profile on gunbroker. It's listed at $200, but prob not actually worth that much...
My guess is that KCI probably originally created the mags for a gov't contract -- likely related to supplying indigenous forces in Iraq/Afghanistan with the Czech's gifting so many of their old VZ58s due to the transition to mixed review Bren, but that's just a guess... If not through Canada, possibly the GB mag made its way back through US military or embassy personnel?
