The Winchester Optics Supreme 6-18x50mm Rifle Scope (model 6-18x50SFIR) is a versatile, second focal plane (SFP) riflescope designed for hunting, varmint shooting, and general range use. It combines solid optical performance, an illuminated reticle, and durable construction at a budget-friendly price.
Key Highlights
- Side Focus Parallax: Unlike many budget scopes that use a front-adjustable objective, this model features a side dial, allowing you to adjust for parallax and image clarity from 10 yards to infinity without breaking your shooting position.
- Illuminated Etched Reticle: Most models in the Supreme line use wire reticles, but the 6-18x and 1-4x models upgrade to an etched glass reticle with an adjustable red center dot, which is much more durable under heavy recoil.
- Zero-Reset Turrets: The turrets are capped to prevent accidental movement in the field but can be easily reset to "zero" using a coin or screwdriver once you've sighted in your rifle.
- Recoil Rating: It is specifically tested to withstand up to 800 Gs of recoil, making it suitable for magnum calibers (like .300 Win Mag) and muzzleloaders.
