I bought a barrel from psa and it wasn't drilled for a fsb and needs to be drilled at the same time as a fresh FSB.

Anyone know where to get one?

E-mail the boys at ADCo and see if they can help...

you can always buy a clamp on FSB for an easier install, beats the the hell out of having to drill but is considered not as sturdy by some. still would be plenty durable enough though. The plus side to this is that you can eliminate an cant in your FSB to have your rear sight zeroed on the windage. check out armalite and fulton armory, they both make clamp on FSBs but i'm not sure if they're F marked or not.

Thought about it, but I'm looking for as much strength as possible. Would suck to lose a FSB when I needed it the most

If it is a virgin barrel, it doesn't matter if the FSB has been previously drilled or not.

pretty sure this one is not f height - call them first to verify before ordering: http://jtdistributing.net/store/product210.html

eta: that one is .625 - i assumed you wanted pure a-1

My gunsmith said it needed to be virgin, something about the jig and the drilling process. .750 under the gas block as well

if this is not a retro project, get a f-fsb it will work just fine with A1/A2 receiver.
you could fill the F marking later.

I'm quite sure ArmaLite doesnt use F-FSB on their rifles and they sell just the FSB but it's a bit pricey
