Set of Front and Rear Flip-Up Sights by ASG, Fiber Optic

These flip up sights make a great backup to any optical sight you may be using. They maintain a low profile when folded down, and flip up at the touch of a button. They are clearly visible due to the built in fiber optic illumination. This set includes both the front and rear sights. These will fit on any 21mm picatinny rail.
