"March, I'm about to purchase a VZ2008. Just to be sure, you can tab these bolts as well, correct? If so, I'll have one headed your way as soon as I can get my hands on it."
Yes I can
"On the tabbed carrier, someone on gunboards made the comment that perhaps the tab should be slanted in front. See text below. From what I can tell the CSA design was squared in front so I suppose that is what people are following and report that it works. But I wonder why it is squared in front like it is. Can anyone offer perspective on why it is typically squarish, or which shape would seem like it should be optimal according to the carrier/disconnect geometry?"
Mine end up rounded and at a slight angle.
"Can we get some more pics of the gas block/front sight combo? Maybe one finished and installed? Thanks... "
I never installed it, however here is a link to someone else's who has:
