Does anyone know of anywhere someone could find one? I've looked and I can't find them anywhere

The closest I've gotten was experimenting on an FSB I cut off to fit under a FF tube.

A bunch of grinding, filing, and sanding got the tower to resemble a cast piece - but it's a lot of work.

Might be worth a try? At least you get rid of those scuzzy forging lines.

DPMS used to use cast FSB.  I had a DCM upper that had one but it didn't have a bayo lug.  But it was a sand casting and the edges were more rounded like a forging versus the cast or injected type of the early ones as evident by the ejector pin marks.  Were the early Armalite FSB even metal or were they die cast out of some sort of alloy?

Sounds like they really are hard to find I figure someday when I least expect it I'll come across one.

Your best bet is to hold out for one mounted on a bbl.,

they show up at shows every now and then.

I can promise you that if you take an existing FSB off a bbl, then try to fit another FSB to it, you'll see why most people (and even 'smiths) don't like FSB swaps.....

Thanks for the info I was wondering how much of a bear it was to change one. I guess the pin holes would have to be redone, and then hope the base seals up right......I'll just hold out till I come across a barrel assembly.
