anything with an A3 should have the F marked front sight base, but it it not required.

You can usualy just jack the front sight out until its sighted in or just buy and extended front sight from Bushmaster.

Get the F marked, you have to have it for aftermarket sights like Trijicon glow posts and such. Its what is designed to be used with a removable carry handle, the regular FSB you need the taller front post if you want to use it with a flattop.
