Description
1-4.5x24 second focal plane riflescope with ATSR3 illuminated reticle, for short-range hunting and tactical use.
The Helos BTR 1-4.5x24 is a low-power variable 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 has a rotation-limiting revolution lock: it is secured with side screws and travels a single full turn, so it returns to zero without second-guessing which revolution the turret is on.
The ATSR3 illuminated reticle has a large illuminated 12 MOA circle for fast target acquisition, a centre dot for precise aim, and 2 MOA hash marks for windage holdover.

- Waterproof, fog proof, shockproof — Sealed one-piece aircraft-grade aluminium tube for reliable use in the field.
