On the gas block BUIS configuration, the front sight post is about 1/4 ” higher than the rear sight aperture so that it could make up for the reason that the front sight is mounted 1/4 ” lower compared to the upper receiver to where the rear sight is being mounted. It is very important to remember that the gas block sights are just for mounting on gas blocks that are lower than its upper receiver. Some of the gas blocks are of the same height as the receiver to where you want the same-plane sight. The same-plane sights are made for the front sight post will be on the same height as the rear aperture if the sights are going to be placed on a flat surface.
