What is a "F" marked front sight?

sovietak474u · Feb 20, 2012

F marked front sight bases are just a bit taller than standard bases. They are used on flat top uppers.

We're talking 0.04 taller. Lol it's hard to notice unless you really look.

I say its not noticeable at all unless your using a micrometer...lol

Ok thanks, I have seen it in several posts and I have one that is, and one that is not marked. Just curious, figgured y'all would know.
