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.
