ok guys, I guess I'll do it. I can always re-thread the barrel to standard AR dia./pitch if I don't like the Fal break as it uses 9/16 dia thread.
I hope to pick up a barrel at knob creek next week and I'll get the hider there too and hand it to my machinest while I'm there since we're riding there together.
I will post pics when it's done.
Thanks,
Jason
