[ARCHIVED THREAD] - which front sight base

Posted: 10/5/2007 12:31:02 PM EDT

I'm looking at getting a CMMG upper and for the front sight base they have 2 options. F marked FSB and standard FSB. If i'm planning to put an ARMS #40L as the rear sight, what FSB would be better? Howabout if I were to get an A2 upper?

F marked is for a flat top

The regular one is for A1,A2 uppers.
