From the manufacturer

Heavy-duty, steel construction makes these emergency front flip sights the tactical shooter's choice for LE and military tasks requiring a compact, backup, sight system of superior strength and dependability. Deploys easily with the flick of your thumb; disengages down, out of your sight path when not in use by depressing the spring-loaded pushbutton. Extra thick, protective ears guard against blows that could potentially bend or break the sight post or aperture. Solid clamp with large crossbolt provides rock solid attachment to Picatinny rail systems. Knurled and slotted, quick-release thumbscrew makes sight easy to install/remove.
