The Knights Armament 45 Degree Offset Tactical Rear folding sight allows the operator to transition from magnified optics to an offset iron sight by simply tilting the weapon. This rear sight can be adjusted without need for tools, and folds away when it is not in use. They can be used on any rifle equipped with a top Mil-Std 1913 Picatinny rail. This is also a great way to add a backup rear iron sight to your scope-equipped rifle.
