Athlon Optics Cronus BTR 4.5-29x56 Tactical Long-Range Riflescope (APRS1 FFP IR MIL Reticle)

Designed for long-range shooting, the Cronus BTR 4.5-29x56 Riflescope from Athlon Optics is suitable for both tactical and hunting. It offers a magnification range of 4.5-29x in a 56mm objective lens. It comes with an improved the parallax adjustment from 25 yards to infinity. At the heart of the scope are Extra Low Dispersion (ED) glass elements that are fully multicoated to produce bright, sharp image with true color reproduction. The riflescope comes with a new APRS1 illuminated reticle with MIL-based subtensions placed in the first focal plane.

Optical Construction

The Cronus BTR 4.5-29x56 Riflescope is equipped with Extra Low Dispersion glass lenses that reduce chromatic aberration giving you bright, high-contrast images with life-like colors. An advanced fully multicoating on the optics help in high light transmission to produce clear images even in low-lit environments. The outer surface of the lenses is coated with Anthon’s XPL coating that provides protection from dirt, oil and scratches.

APRS1 MIL First Focal Plane Reticle

Placed at the first focal plane, the APRS1 reticle is suitable for long-range shooting applications with accurate ranging capability. It offers quick target engagement at low power as well as precise holdover positions with finer details. This specially designed reticle shrinks or grows along with your target as you zoom in or out. It is illuminated to provide greater visibility in low light environments. Glass etching MIL subtensions provide high durability and shock resistance to recoil.

Ergonomic Controls

The Athlon Optics Cronus BTR 4.5-29x56 comes packed with features like precision zero stop system, high precision erector system, and an exposed tactical direct dial. Its heat-treated single-tube aluminum construction gives the scope extra stability more than multi-piece tubes. The one-piece tube construction also helps in keeping the internal optics free from moisture and dust.

Waterproof, Fogproof, and Shockproof

The Cronus BTR 4.5-29x56 Riflescope is designed to work in harsh environmental conditions. It is waterproof and Argon purged for complete fogproof performance in varying temperature ranges. The scope can also withstand up to 1000G recoil for 1000 times.
