I was trying to install a FSB on my new DD 16inch/pencil barrel and noticed that the underside of the barrel does not have a flat area for the FSB pins to go through....What type of Front Site Base do i need....
Thanks,

I think those were intended for gas blocks, not FSB towers.  To install a standard FSB you need a jig to make sure the base is top dead center, otherwise it will end up canted.  Drill and ream with a 2/0 reamer and insert taper pins.  For a low profile or set screw gas block you would just have to dimple the barrel for set screws.  There are also gas blocks that clamp onto the barrel.

see how to install a FSB here: www.brdengineering.com

Bravo should have the jigs available anytime.
