Okay, so I recently had an A2 style FSB installed on my AR and I thought it was F height but it does not marked. How tall is an F marked FSB compared to an A2?

Not to hijack or anything, but is there any real advantage/disadvantage in using one over the other? The reason I ask is that I'm probably going to get an armalite flat top upper sooner or later, but their FSBs are not F marked. I'd probably end end up replacing it with a railed gas block anyways, but it's been on my mind a while now.
it will matter when you attempt to zero @50 yards
