Product Description

This 4-16X42 SFIRF Rifle Scope combines tactical precision with versatile performance for long-range shooting, featuring a Side Focus (SF) mechanism for parallax correction from 50m to infinity and an Illuminated Reticle (IR) with 6-level red/green brightness. The Mil-Dot reticle supports ballistic calculations for windage and elevation, ideal for 300–1000m engagements, while multi-layer broadband coating enhances light transmission by 95% for clear, high-contrast imagery in dawn/dusk conditions. The 42mm objective lens balances light gathering with a compact profile (13.8" length, 22oz weight), mounting seamlessly on Picatinny/Weaver rails. Crafted from rugged 6061-T6 aircraft aluminum, the scope withstands heavy recoil from .308 Win to 6.5 Creedmoor, with nitrogen-purged fogproofing and IP67 waterproofing (1m submersion) for all-weather reliability. 1/4 MOA finger-adjustable turrets offer precise windage/elevation corrections with audible clicks, while the side focus wheel enables one-handed parallax adjustments for rapid target acquisition. The illuminated reticle eliminates aiming errors in low-light environments, with an auto-shutoff function after 2 hours to conserve battery life. Whether zeroing at the range or engaging targets in tactical scenarios, this SFIRF scope’s combination of optical clarity, rugged construction, and tactical features makes it essential for precision shooters. The hard-anodized finish resists corrosion and scratches, while the fast-focus eyepiece ensures rapid reticle clarity—delivering reliable performance for competitive shooting, hunting, or professional tactical operations.
