I'm looking to do something different with my sights.  I currently have a carry handle rear sight on my BCM flatop upper reciever with the fixed front sight.

Im wanting to go with a non folding BUIS and then an optic.  There is a group buy on a aimpoint comp m2 and I thought that would be a good start for a optic and then I need to put a BUIS behind that.  My questions are:

Are there different heights on the rear sights?

I was looking at the Danial Defense A1.5 Fixed Rear Sight or the LaRue Tactical B.U.I.S. QD LT-103.  Am I looking at the correct equipment for what Im trying to accomplish?



Thanks in advance for the help.

Both of those sights will work, the front sight post has enough travel to compensate for a potential height change.  Taller front sight posts are available from Bushmaster if you have excessive adjustment.  I prefer the DD 1.5 because it has a fixed mount so I know it will stay put.

The BCM uppers have the taller front sight post, i just wasnt sure if the rear sight had to be taller or if there were different sizes to work with the taller front sights.

Thanks

The front sight is taller on carbines to compensate for the shorter sight radius and barrel, to match the standard length trajectory.  The rear sights are the same.
