GG&G Tactical's Spring Actuated Flip Up Front Sight For Tactical Forearms has been redesigned to be lighter in weight and quicker in deployment. Although specifically designed to provide the correct sight height when mounted on a tactical forearm, the sight can also be installed on gas blocks that are the same height as the upper receiver. With the push of a button the front flip up sight can be quickly deployed on target. The sight not only springs into an on target position, but solidly locks into the deployed position, preventing accidental depression of the sight during a tactical situation. Another push of the button and the sight is free to be folded into the locked down position. The sight actuator button has been located on the left side of the sight, facilitating easy operation with the off hand, leaving your fire control hand in the proper tactical position-near the trigger. The sight is set for use on the AR-15 but will also co-witness when mounted to the tactical forearm of an AR-10. The sight stem has been designed to fold rearward.
