The Nightforce Rear Sight Peep Aperture Insert 300 Meter Black is a compact accessory designed to refine the sight picture on compatible flip-up rear sights. Snapping into the existing 300 meter rear sight aperture, this insert constricts the opening to provide a cleaner, more defined view of your target at intermediate distances.

This insert is ideal for shooters who want more precision from their backup iron sights during range sessions or training without adding bulk or weight to the rifle. By tightening the peep aperture, it helps the eye naturally center the front sight for more consistent shot placement. It is a simple, drop-in upgrade that leverages the manufacturer’s attention to detail and proven sight design.
