Another FSP/FSB thread - Colt 6720
I can't find this anywhere here or on the web, so if you know of a thread that already answers the question, feel free to post a link to it.
So...Colt 6720...is the front sight "F" height or not? I have a hard time believing it's not. All my tools are packed up and I'd like to know. Also, for educational purposes, can someone tell me what the existing markings mean? Is this just a Colt thing and is it common to all their rifles?
