I look around assorted catalogs and see open (iron) sights that can be mounted on a "mil spec 1913" Picatinny rail for AR15s. Is the Picatinny rail for an AR platform different size due to the larger frame, or can AR15 sights fit on an AR10. I am looking to mount back up flip up sights on a Bushmaster 308 ORC which has a Picatinny rail on top.
