Description
4-20x50 first focal plane riflescope with APRS6 illuminated reticle, for precision competition and long-range shooting.
The Helos BTR GEN2 4-20x50 is a riflescope with advanced fully multi-coated glass for enhanced light transmission and true colour across the field of view. An XPL protective coating on the exterior lenses resists dirt, oil and scratches. A 30 mm one-piece aircraft-grade aluminium tube is argon purged and sealed for waterproof, fog proof, shockproof use in the field. The elevation turret carries a precision zero stop, and both turrets lock in place: pull up to dial, push down to lock.
The APRS6 illuminated reticle is designed for precision rifle series competition and other long-range shooting, with a floating 0.05 mil centre dot and 0.2 mil hash-mark increments in all four directions for fast ranging, holdover and wind correction.
