Heavy-duty, steel construction makes these emergency rear 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 Weaver or Picatinny rail systems. Knurled and slotted, quick-release thumbscrew makes sight easy to install/remove. Rear Flip Sight's low-profile design attaches to A4 flattop receivers and regulates correctly with standard, M16/M4 front sights, as well as all Yankee Hill front sights. Rugged, steel base features an aluminum stem to keep weight to a minimum. Deploys instantly with thumb pressure. Large, knurled, screw head provides 1⁄2 M.O.A. windage adjustment. Includes flip-style aperture with .065" and .200" diameter peepholes for short- and long-range accuracy.
