Rear Back Up Polymer Sight flip up with Windage Adjustment

The Mission First Tactical Rear Back Up Polymer Sight flip up with Windage Adjustment (BUPSWR) is a dedicated secondary aiming system designed for rifles equipped with 1913 Picatinny rails. Built from military-grade reinforced polyamide and manufactured in the USA, this backup sight delivers reliable target acquisition when primary optics fail or require removal. The polymer construction keeps weight minimal while providing the durability operators depend on in high-stress environments.

Windage adjustment is controlled via flathead screwdriver with infinite MOA capability, allowing precise zero compensation without switching sight models. The protective shroud design shelters the aperture from debris, impact damage, and environmental contamination when the sight remains folded—a critical feature for rifles stored in vehicles, carried in tactical gear, or deployed in dusty or wet conditions. The slim profile permits operation under all current magnified optics and red dot sights without interference or cowitness obstruction, enabling users to select backup aiming without sacrificing primary sight picture.

This sight is purpose-built for patrol rifles, tactical carbines, and duty weapons where redundant aiming systems are non-negotiable. LEOs, military personnel, and serious sport shooters rely on flip-up backup sights to maintain functional rifles after optic loss or during transition-based shooting drills. The BUPSWR bridges the gap between lightweight backup optics and co-mounted iron sight systems, offering compact, dependable secondary targeting without the bulk of traditional fixed rear sight installations.
