The Geissele Folding Rear Back Up Iron Sight is made from 6061-T6 aluminum and is Type 3 hard coat anodized to ensure extreme durability.
For optimal aiming precision, the sight can be adjusted at ½” increments at 100 yards. The adjustments are captive to ensure that once sighted-in, there won’t be any adjustments that weren't intended by the user.
The sight has no buttons or mechanisms to accidentally bump that will activate or fold down your sights when you least expect it, simply move them up to lock into position, or apply sideward pressure to the vertical tower to lock them down.
These sights are accurate enough for precision use during competition, and rugged enough for duty and personal defense use. The peep aperture is 0.10”.
