Pop up sights for ar-15. Can they be mounted on each end the receiver picatinny rail?
Fellow Grunts: I GOT A GREAT DEAL ON A BUSHMASTER C15 WITH BUSHNELL RED DOT SIGHT. I ALSO GOT A NICE SET OF POP UP TACTICAL SIGHTS. The front sight won't fit the gas block tube. Will I have any problems if I mount them BOTH on the receiver picatinny rail, at either end, about 9'" ins. apart. They went on good and SIGHT PICTURE LOOKS FINE but the short sighting distance, might cause a problem. Does anyone know? HELP!
THANKS AND GOD BLESS
Jerry
