Samson True Backup Sight Features The Samson True Backup Sight uses a single .160 aperture rather than the dual apertures found on many backup sights a deliberate choice that keeps the sight picture fast and simple for a sight that is meant to back up a primary optic rather than replace it. That single aperture is small enough to support accurate shooting at distance yet large enough to remain usable in low-light conditions when speed matters more than precision. The sight accepts all aftermarket front sight post replacements built to mil-spec dimensions giving shooters the flexibility to fine-tune zero or swap in a preferred post design. A windage-adjustable rear sight lets shooters dial in horizontal zero without needing to adjust the front post. Both the front and rear sights fold flat against the rail when not in use and lock securely in both the folded and deployed positions eliminating the snag points and accidental deployment issues seen on lesser backup sights. The durable aluminum construction keeps weight low while the solid mounting system and stainless steel clamp guarantee the sight holds zero under recoil and rough handling. Designed to sit at a perfect M4 co-witness height the True Backup Sight lines up correctly behind a red dot or low power optic for an immediate backup sighting option if the primary optic fails. Mounting to any Picatinny rail the Samson True Backup Sight is a dependable addition to any AR-15 build for sale at GrabAGun.
