The A2 Spring Actuated Back Up Iron Sight (BUIS) represents GG'G's latest innovation in BUIS products. The design of the spring-actuated mechanism captivates the actuator spring and mechanical components, preventing adverse environmental contact. The design also provides the operator the ability to activate the push button with the non-fire control hand ensuring the user a tactical advantage under any condition. The locking mechanism functions for both the raised and lowered position, completely eliminating the potential of accidentally raising or lowering the sight and providing a low-profile stance when lowered to allow the use of most optics.
