Viridian EON Rifle Scope 4-12x42 1" SFP AO FMC Duplex Black

The Viridian EON Rifle Scope 4-12x42 1" SFP AO FMC Duplex Black delivers precision optics for tactical shooters, hunters, and law enforcement professionals who demand reliability in variable-distance engagements. This mid-range magnification riflescope bridges the gap between close-quarter speed and extended-range accuracy, making it ideal for hunters working diverse terrain, 3-gun competitors, and duty operators running intermediate to long-range carbines. Weighing just 1.42 lbs, the compact 17.4-inch profile balances optical performance with minimal impact to rifle balance and maneuverability.

The 4-12x magnification range provides low-power versatility for rapid target acquisition and shooting on the move, while the 12x top end resolves distant targets with clarity for precision shots beyond 300 yards. The 42mm objective lens gathers sufficient light for dim-light shooting while remaining compact enough for standard-height scope rings, a critical balance for weapons that must transition between variable lighting conditions. The single-plane focal plane (SFP) reticle scales proportionally with magnification, simplifying holdover calculations across the power range, while the fully multi-coated (FMC) optics maximize light transmission for edge-to-edge clarity. The 1-inch tube diameter ensures broad compatibility with modern tactical mounts and rings while the adjustable objective (AO) eliminates parallax error—essential for precision work at distance where even minor sight picture shifts degrade accuracy.

This scope performs best on AR-platform rifles, bolt-action hunting rifles, and precision carbines firing intermediate or rifle-class cartridges from .223 Remington through .308 Winchester and beyond. The duplex reticle and fixed 1-inch tube diameter integrate seamlessly with standard Picatinny rails via conventional scope rings—no special adapters required. Law enforcement and military users will appreciate the rugged all-black matte finish that resists reflection, while hunters benefit from the optical clarity and compact form factor that won't bind with modern furniture or create unnecessary weight penalty. Installation requires only a torque wrench and basic gunsmithing knowledge to ring and level; professional mounting is always recommended to ensure proper zero retention and reliability under recoil.
