The ERA-TAC Backup-Sight with Red Fiber-Optic Insert (MPN: T0953-0016) is a mechanical, scope-mounted emergency sighting system engineered by Recknagel in Germany. Designed to integrate directly onto the top surfaces of ERA-TAC one-piece and two-piece tactical mounts via the proprietary UNIVERSAL-interface, it enables an immediate transition to open sights without requiring the removal or uncoupling of the primary riflescope. Operating entirely via ambient light, the system pairs a protected front red fiber-optic bead with a rear ghost ring sight, providing reliable sighting redundancy during optical lens occlusion, battery depletion, or primary optic failure.

Key Features

• Direct Interface Integration: Fastens directly to ERA-TAC mounts featuring the proprietary UNIVERSAL-interface, preserving rifle scope zero while co-existing above standard scope tubes.
• Calibrated Mechanical Adjustments: Features click adjustments calibrated to 1 MOA (3 cm at 100 m) across a total elevation and windage range of 240 cm at 100 m.
• Ambient Red Fiber-Optic Aiming: Utilises a passive red fiber-optic front insert enclosed by protective side wings for high-contrast target acquisition without batteries or electronics.
• Heavy Recoil Rating: Shockproof and recoil-proof across heavy tactical and magnum hunting calibres up to .50 BMG when installed to factory specifications.
• Corrosion-Resistant Mil-Spec Construction: Machined with protective raised sidewalls designed to shield the front post and rear aperture against mechanical impacts.

Who is the Era-Tac Backup-Sight With Red Fiber-Optic-Insert for?

• Tactical shooters running ERA-TAC mount systems — Requires the proprietary ERA-TAC UNIVERSAL-interface to bolt this scope-mounted backup iron sight directly over the primary optic, clearing turrets up to 11 mm on the front interface and 15 mm on the rear interface without additional risers.
• Hunters pursuing dangerous game needing redundant sighting — Delivers emergency mechanical sighting with 240 cm of total adjustment range at 100 m, allowing zeroing retention across heavy-recoil platforms up to .50 BMG without removing the primary glass.
• Duty rifle operators operating in harsh weather environments — Provides non-electronic optical redundancy via calibrated 1 MOA (3 cm at 100 m) clicks and a passive ambient-light fiber-optic post when primary optical scopes are occluded by snow, mud, or moisture.

Less suitable for: Standard Picatinny receivers without ERA-TAC UNIVERSAL-interface hardware (which require standard rail-mounted backup iron sights), scope setups where turret heights exceed 11 mm front or 15 mm rear without dedicated interface spacers, or long-range target engagements beyond typical iron-sight thresholds of 200 to 300+ metres, which are better served by primary magnified riflescopes.
