The GG&G A2 AR 15 Spring Flip-Up Rear Sight is one of the best-selling Back Up Iron Sights (BUIS) on the market today! Many operators have been craving a GG&G A2 BUIS Rear Flip Sight that would deploy with just a push of a button, and now GG&G has fulfilled that wish. The unique and proprietary design of the spring site mechanism allows the actuator spring and mechanical components to be captivated, so the mechanisms are not open to the elements. The GG&G Flip Up Sight not only springs into an on target position with just the push of the actuator button, but it also locks solidly into the upright on target position. Another push of the button and the lock is released allowing you to set the spring sight into the locked down position. This totally eliminates the possibility of accidentally lowering the A2 flip sight. The sights are equipped with the GGG tactile grip windage knob, so adjustments are easy and precise. These iron sights provide the operator with an easy-to-install and easy-to-operate low-profile BUIS that's ready to go when you need it.
The GG&G A2 Spring Actuated BUIS Sight provides the operator with an easy-to-install push button operated AR 15 flip up sight. The GGG Spring Actuated A2 BUIS can be used as a stand-alone sight or in conjunction with a GG&G Rail. It can also be used as a co-witness iron sight with most red dot sighting systems. Weighing in at just over 2.4 ounces, this flip sight features the standard military A2-style double peep aperture which allows for end user known point of impact. The GGG AR15 Flip Up Rear Sight has full windage adjustment with standard military windage knob and windage screw - meaning there's no need to retrain. One click of the windage knob provides approximately 0.48 MOA change when mounted on the M16A2E4 rifle and about 0.65 MOA on the AC carbine. Initial zero is set by adjusting the weapons front sight post. It is low profile so that when in the down position, it will clear most optics. The mount body and sight stem are manufactured from solid billet 6061 T6 aluminum alloy and Type III hard coat anodized in a non-reflective black mil-spec finish to provide combat durability. All steel components are black manganese phosphated per mil-spec.
Available options for the GG&G Folding Spring Rear Sight include the XS same plane aperture, or Trijicon Tritium aperture. Except for these optional apertures, all components are standard M16A2 sight components.
