The GG&G A2 Spring Actuated BUIS (Back Up Iron Sight) is the latest evolution to the BUIS product line. The unique and proprietary design of the spring site mechanism allows the actuator spring and mechanical components to be captivated and therefore not be open to the environmental elements. The 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. The flip rear sight cannot be folded down without depressing the actuator button located on the left side of the sight base. This totally eliminates the possibility of accidentally lowering the A2 flip sight. Equipped with the GG&G tactile grip windage knob, adjustments are easy and precise.
The GG&G A2 Spring Actuated BUIS provides the operator with an easy-to-install push button operated AR 15 flip up sight and can also be used as a co-witness iron sight with most red dot sighting systems. Weighing in at just over 2.4 ounces, it features the standard military A2-style double peep aperture which allows for end user known point of impact. The AR15 flip up rear sight has full windage adjustment with standard military windage knob and windage screw. 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 M4 carbine. 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 |
