This is our high quality, 6061-T6 aluminum flat top A2 style Carry Handle. It has a long range Mil-Spec rear sight with windage and elevation adjustment. The full-length bar mount clamps tightly with 2 large thumb nuts to any Picatinny flat top receiver.
Features: This carry handle tightens down via an allen wrench, which IMHO secures it much better than the big knobs with flat screwdriver slot that sticks out on other carry handles!
