KAC-Knight's Armament 200-600 Meter Flip-Up Rear Sight

KAC-Knight's Armament 200-600 Meter Flip-Up Rear Sight (98474)

Mounts to flat top upper. Flip-up sight stays down out of the way when using optics, yet is easily flipped up. Windage and elevation adjustable.

Older, classic style.  A cloner's must have for the MK12 build.  Essentially does the same job as KAC 25650 with a bigger base and knob.  Great for when you're keeping it old school.
