NC Star AR-15 Picatinny Low Profile Front and Rear Sight Set Features The NcStar Picatinny Low Profile Front and Rear Sight Set mounts directly onto a 1913 MIL-STD Picatinny rail giving AR-15 owners a quick tool assisted installation on any compatible receiver or rail section. The rear sight incorporates a dual aperture peep design letting the shooter choose between a larger aperture for close range target acquisition and a smaller one for more precise aiming at distance. An adjustable windage knob on the rear sight allows the shooter to fine tune horizontal zero without needing additional tools. The front sight pairs an adjustable post with an elevation knob giving the shooter control over vertical zero to match the rear sight s windage adjustment. Both sights use a flip up design folding down flush with the rail when not needed and popping up quickly thanks to heavy duty internal springs. This low profile height keeps the sights out of the way when running a magnified optic or red dot while remaining ready as a backup sighting system when needed. Precision machined metal internal parts are paired with a durable impact resistant polymer housing balancing durability with a lightweight overall package at just 1.60 ounces. All necessary mounting hardware is included making this set a simple and effective upgrade for any Picatinny equipped AR-15 platform.
