Serpent arms exclusive iron sights utilize a flip-up design and fiber optic dots for both front and rear sights. This electronic free and easy to adjust sight also includes two different sized peep holes for faster sight picture acquistion or finer accuracy. The iron sight directly attaches to any picatinny rail and works great for both our Air Shotgun and our Air Rifle.  The iron sights are colored in olive green to match our awesome airgun color.
