GG&G 1281SA Flip-Up Front Sight for Gas Blocks

The unique and proprietary design of the mechanism allows the actuator spring and mechanical components to be captivated and therefore not be open to environmental elements. The 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 sight into the locked down position. The 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 sight.
