Removing pinned F2 Sight and installing Vltor pinned flipup

[Gramps]

IF, I remove my pinned F2 front sight, will the pins on a Vltor pinned fsb line up with the stock ones on my CD Defense Carbine? Or are they done per sight/gb/barrel. I'm hoping they are a standard spacing, but would rather ask, than be unhappy. A question asked, could be $ saved.
Thanks, Gramps

Your new gas block will not line up. They never do. It's best if you have a shop install it.
