Athlon Cronus BTR 4.5-29×56 FFP Illuminated Mil 34mm Riflescope

Whether you want to do precision long-range shooting and tactical applications, or extreme long range hunting adventures, the new Athlon Cronus BTR 4.5-29×52 riflescope is just what the doctor ordered.  With all of the same key features of the Cronus line, the new Athlon Cronus BTR 4.5-29×56 is redesigned to be even better!  We improved the parallax adjustment yard markings to go from 25 yards to infinity (added markings at 300, 500, 800 and 1600 yards), designed a new reticle as well as re-designed the battery compartment to make it easier to adjust the illumination.  The best just got better!

The Athlon Cronus BTR 4.5-29×56 Model has APRS first focal plane illuminated MIL reticle in it.  Please click the link for detailed reticle subtension…

Athlon BTR 4.5-29x56 APRS FFP IR Mil
Athlon Cronus BTR 4.5-29×56 FFP Illuminated Mil

Designed for precision rifle series competition and any other long range shooting applications with accurate ranging capability, APRS MIL reticle can help you quickly determine distance, holdover positions, windage correction and leads for a moving target. The unique design of fine .2 mil hash mark increments from centre to 6 mils at both directions of the horizontal base line helps the shooter set a quick windage holdover position after they dialled in elevation on their targets. The floating 0.4 mil span centre cross draws a shooter’s vision right on target enabling him or her to engage a target at a blink of an eye. The illuminated fine reticle provides excellent low light visibility and windage holdovers on the bullet droplines all the way up to 10 mils.
