Product Description The Athlon Argos HMR 4-20x50mm Riflescope is a compact and versatile hunting and long-range shooting optic designed with practicality in mind. Featuring a Second Focal Plane (SFP) layout and an illuminated BDC 600A reticle, this scope delivers precise holdover references for bullet drop compensation and wind drift at extended ranges. Built around a one-piece, heat-treated aircraft-grade aluminum main tube and finished with Advanced Fully Multicoated lenses, the Argos HMR provides a bright, clear sight picture across its full 4-20x magnification range. Argon purging keeps the interior fog-free and waterproof under demanding field conditions, while capped elevation and windage turrets protect zero settings during transport and use. Product Highlights BDC 600A Illuminated Reticle - Features hold-over points for bullet drop and wind drift compensation, compatible with a wide range of popular hunting cartridges including .308 Win, .270 Win, 7mm Rem Mag, and more. Advanced Fully Multicoated Lenses - Reduces light reflection and maximizes light transmission for a brighter, crystal-clear image in all lighting conditions. One-Piece Heat Treated Aircraft-Grade Aluminum Tube - Provides superior strength, moisture protection, and recoil resistance compared to multi-piece tube designs. Argon Purged and Waterproof - Internal argon gas purging ensures fog-proof and waterproof performance, keeping optics clear in rain, humidity, or extreme temperature changes. Side Parallax Adjustment (10yds - Infinity) - Allows for precise parallax correction across a broad range of distances, ensuring a sharp and accurate sight picture at any range.
