Pop up sights for ar-15. Can they be mounted on each end the receiver picatinny rail?

They should go on...but not much sight radius there. Why not just use the optic? Why doesn't the front sight fit? Maybe it's not such a good deal then...

What he said.

Or get a free-float fore-end with a top rail and do it properly.

free-float fore-end

You can even get a full length rail to consolidate the upper and front rail so there's no possibility of movement after zeroing.
