NcStar Picatinny High Profile Front and Rear Sight Set Features The NcStar Picatinny High Profile Front and Rear Sight Set pairs a dual aperture peep rear sight with an adjustable post front sight to give shooters a complete backup sighting solution. The rear sight s dual aperture design gives shooters a choice between a larger aperture for fast target acquisition and a smaller one for finer precision work at distance. An adjustable windage knob lets the shooter dial in horizontal zero without tools while the front sight s elevation knob handles vertical adjustment so both sights work together for an accurate point of impact. Each sight mounts directly to a standard 1913 MIL-STD Picatinny rail making installation straightforward on any AR-15 platform rifle already equipped with rail sections and the flip-up design means both sights can be folded down out of the way when a magnified optic is the primary sighting system. Heavy duty springs drive the flip-up mechanism giving the sights a positive reliable deployment every time they are needed in a hurry. Precision machined metal parts reinforce the critical moving components adding strength and consistency beyond what an all-polymer sight could offer. At just 2 oz combined and finished in a non-reflective black the set measures a compact 1.30 inches in both height and width keeping the rifle s profile low and balanced. Built from impact resistant high quality polymer paired with metal internals this set is a durable lightweight backup sighting solution for duty range and general AR-15 use.
